Accord Odette FTP
 
The Accord Odette FTP is an open sourced - AGPL - Java library API that implements both {{{./rfc5024.html}RFC 5024}} and {{{http://ietfdocs.potaroo.net/idref/rfc2204}RFC 2204}} giving users and developers support for exchanging files with partners either running with OFTP server version 1.3, 1.4 or the new 2.0 version. This and many other features can be only found in Accord Odette FTP library. It is implemented under Java 5 and based on JBoss Netty.
 
 
[accord-oftp-1.png] Accord Architecture
 
 
* Key Benefits
 
* Support for OFTP 1.3, 1.4 and 2.0
 
* Auto backward compatibility
 
* Support for unique version mode
 
* Support for SSL client authentication
 
* File compression
 
* File restart
 
* Push and pull operations
 
* Support for sending End-to-End response (EERP) also know as file delivery receipt
 
* Digital signatures
 
* Certificates
 
* Support for TCP/IP transport
 
* Support for X.25 transport
 
* Secure transport over SSL
 
* Asynchronized and event-based architecture
 
* Open Sourced through the Affero GPL 3.0
 
* Java Integration
 
Because it is a Java library, it can be easily embedded within any Java software. This gives customers freedom and flexibility on how to build their own B2B solutions.
 
* Java 5
 
* Generified API
 
* Deployed on {{{http://oss.sonatype.org}Sonatype}}'s {{{http://maven.apache.org}Apache Maven}} repository
 
* Designed for developers and software architects
 
* Based on {{{http://www.jboss.org/netty}JBoss Netty}}
 
* Encryption and signatures
 
The Accord Odette FTP library supports the following encryption/hash algorithms, required by the Odette International organization:
 
* AES-256
 
* 3DES
 
* SHA-1
 
Other algorithms might be supported as well, through the {{{http://www.oracle.com/technetwork/java/javase/tech/index-jsp-136007.html}Java Cryptography Extension (JCE) layer}}.
 
* Apache Camel integration
 
If you are already using or considering to use {{{http://camel.apache.org}Apache Camel}} on your project, you can take advantage of the {{{camel.html}Camel OFTP}} component.
 
* Comparison to
 
The {{{http://oftp2.mendelson-e-c.com/}mendelson project}} only offers a Java client with support for OFTP 2.0. Because of that, it cannot be easily embedded to third-party software. Also it does not support older versions of the Odette FTP specification (1.3 and 1.4).
 
* Graphical User Interface for Accord Odette FTP
 
If you are looking for an end-user GUI for your desktop to connect to your b2B partners, go to the {{{../wire/index.html}Accord Wire}} project.
 
* Commercial Support
 
{{{http://www.neociclo.com}Neociclo}} is the company behind the Accord MFT Suite, also developing other projects designed to leverage and simplify the task of managing file transfers.

Quick Start
 
Reading the Javadocs won't get you started exchanging files through the OFTP protocol. So follow these instructions on how to start developing your own OFTP-enabled Java program. This is a library that implements the OFTP protocol so from here, you have to develop your own GUI interface, either console or desktop.
 
[[2]] Check-out the Odette FTP library
 
+------------------------------------------+
$ svn co svn checkout svn://svn.forge.objectweb.org/svnroot/accord/odetteftp/trunk odetteftp
+------------------------------------------+
 
[[3]] Build and install the Core API on your local repository
 
+------------------------------------------+
$ cd odetteftp/core
$ mvn install
+------------------------------------------+
 
[[4]] Create a Maven quickstart project
 
+------------------------------------------+
$ cd ~/
$ mvn archetype:generate -B -DarchetypeGroupId=org.apache.maven.archetypes
\ -DarchetypeArtifactId=maven-archetype-quickstart
\ -DgroupId=com.mycompany -DartifactId=myproject
+------------------------------------------+
 
[[5]] Edit the file <<myproject/pom.xml>> and add the following dependency:
 
+------------------------------------------+
<dependency>
<groupId>org.neociclo.accord.odetteftp</groupId>
<artifactId>core-oftp</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
+------------------------------------------+
 
[[6]] Configure the project for your IDE
 
[[a]] Eclipse:
 
+------------------------------------------+
$ cd myproject
$ mvn eclipse:eclipse
+------------------------------------------+
 
[[7]] Import the project to your IDE's workspace
 
[[8]] Edit <<src/main/java/com/mycompany/App.java>> and start coding!
 
Examples
 
These are snippets of examples found on the {{{./examples-oftp/index.html}examples}} module. You may look the source code for more details. Although the Accord OFTP has server feature, these examples were coded to validate the library by sending commands to a remote server running (probably) some other implementation. You must know one OFTP server up and running to run these tests.
 
* Connect and Disconnect
 
This gives you a "Hello Odette!" snippet that connects and then disconnects from the remote OFTP server.
 
+------------------------------------------+
String server = "10.0.0.1";
int port = 33005;
String odetteid = "MYODETTEID";
String password = "MYODETTEPWS";
 
SessionConfig conf = new SessionConfig();
conf.setUserCode(odetteid);
conf.setUserPassword(password);
 
OftpletFactory factory = new DefaultOftpletFactory(conf);
TcpClient oftp = new TcpClient(server, port, factory);
 
oftp.connect(true);
+------------------------------------------+
 
* Sending File
 
Sending a file is the most important task the API must accomplish, right? See how it goes:
 
+------------------------------------------+
conf.setTransferMode(SENDER_ONLY);
 
File payload = new File(args[4]);
DefaultVirtualFile vf = new DefaultVirtualFile();
vf.setFile(payload);
 
Queue<OdetteFtpObject> filesToSend = new ConcurrentLinkedQueue<OdetteFtpObject>();
filesToSend.offer(vf);
 
OftpletFactory factory = new InOutSharedQueueOftpletFactory(conf, filesToSend, null, null);
TcpClient oftp = new TcpClient(host, port, factory);
 
oftp.connect(true);

Accord Odette FTP Camel Component
 
The Camel OFTP Component is an adaptor for the {{{http://camel.apache.org}Apache Camel}} framework that enables developers to leverage Odette FTP support on scenarios of file transfer between B2B applications. It is well suited for projects that need to have support for OFTP 1.3, 1.4 and OFTP2 on ESBs (Enterprise Service Bus) like {{{http://servicemix.apache.org}Apache ServiceMix}}., JEE-based applications and any route-enabled architectures.
 
Quick Start
 
To enable OFTP2 support on a Camel project, it is required to add a Maven dependency for the Accord Camel OFTP component:
 
+-------------------------------+
<dependency>
<groupId>org.neociclo.accord.odetteftp</groupId>
<artifactId>camel-oftp</artifactId>
<version>1.2-SNAPSHOT</version>
</dependency>
+-------------------------------+
 
We hardly recommend to use {{{http://maven.apache.org}Apache Maven}} to integrate this component within your application. If you are not using Maven, you can download Apache Camel's distribution and then download Accord Odette Camel from Maven repository. We are not planing on releasing
 
Example
 
+-------------------------------+
from("oftp://odetteid:password@10.10.1.1?workpath=odette/work")
.to("file:odette/inbox");
+-------------------------------+
 
You can check more examples on project's unit tests.
 
How it works
 
Each endpoint connects to a remote OFTP server. It is possible to send and receive files, as well delivery notifications (EERPs). To receive anything, one must configure the endpoint as consumer, like in the example above.
 
To send files or Delivery Notifications, the endpoint must be configured as producer. If you want to send and receive files, two routes are needed.
 
The component will use the same OFTP session to both send and receive data if applicable. This means outgoing data sent to an OFTP endpoint will be actually delivered when a connection is estabilished, saving resources. An internal queue is used to store this outgoing data. In the mean time, incoming data will be sent to endpoint's consumer.
 
It is, however, possible to have an endpoint with both consumer and producer, but on specific OFTP transfer modes. This is necessary to be able to send Delivery Notifications on different sessions. For instance, when a file arrives but no EERP is sent back automatically.
 
Reference
 
The Camel OFTP component's URI follows the pattern below:
 
+-------------------------------+
oftp[s]://[oid[:pass]@]hostname[:port]?param=value
+-------------------------------+
 
<<Observation:>>
 
<<<If URI is preffixed with 'oftps' scheme, then SSL will be enabled>>>

OFTP2 Protocol Overview
 
The Odette File Transfer Protocol was originally designed by the Odette International organization, formed by the automotive industry, aimed to set a standard on EDI exchange between business partners. The first version was specified to support file transfer over X.25 networks and later over ISDN. Now the OFTP2 specification adds, among other features, support for transport over TCP/IP, TLS for session encryption, file encryption and authentication based on digital signature.
 
One might put OFTP side-by-side with FTP or SFTP, but these are pure file transfers, without any business model applied on the file transfer process. What developers accomplish by writting many scripts to achieve file receipt, OFTP has this in its core.
 
The main difference between OFTP and S/FTP is that OFTP leverages the B2B scenario over file transfers. Also, from the OFTP user's perspective, there's no client/server nor folders to access, files to list. A partner basically connects to another and notifies it of a file delivery request or is notified about an incoming file request. The protocol does not specify where files should be put or where they should come from to be sent. The application implementing the protocol is responsible for that.
 
A key benefit of the protocol is that it has file delivery receipt. This is important, again, on the B2B scenario. Today system admins and developers have to define on both sides of a B2B integrated solution a way to inform that transfered files were correctly processed. This is defined as <End to End Response> and is described on {{{./rfc5024.html#section-3.3.5}section 3.3.5}} of the {{{./rfc5024.html}RFC 5024}}.
 
Below you will find diagrams and better explanations that might help you to understand how OFTP works.
 
* The first big picture
 
[oftp-file-transfer-scheme.png] First big picture
 
Here, two partners have estabilished a 2-way connection (explained later), to both receive and send files. Usually, applications implementing OFTP offer a way to specify inbox and outbox folders. These are represented here. The protocol does not access these folders. It is applications' responsibility to pull the outbox folder to send files, and to write incoming data to a file in the inbox. The sender has no control on how or where its sent files will be placed.
 
One important thing: before any transfer, both partners must agree with it. Before a file transfer beggins, one might check the file name and if it is invalid, sends to the other partner a command rejecting the file transfer. This works on both sides, when the partner is receiving a file.
 
* Virtual File
 
[oftp-virtual-file.png] Virtual File Diagram
 
As OFTP does not specify a file system to navigate through remote files, these have to be mapped to <<Virtual Files>>. There's no virtual folder too. On the Core API of the Odette FTP Library, you will find a class with that name to map between <<java.io.File>> and a <<VirtualFile>> object.
The reason OFTP specifies a virtual file is to make it possible to have a different file name. It also has a list of options to set, for example, the partner who will receive that file. This works this way because sometimes the remote partner is not the one who must process it, but he will only forward the file to the destination.
 
* Peer-to-peer Transfers
 
[oftp-peer-to-peer.png] Peer-to-peer
 
The first and obvious scenario is a peer-to-peer, or in better words, partner-to-partner. For any file sent from partner A to partner B, the second must send an {{{./rfc5024.html#section-3.3.5}End-to-End Response}}. If something goes wrong, it will send a {{{./rfc5024.html#section-3.3.6}Nevagite End Response}}. This feature is one of the most important of the Odette FTP. If partner A gets a NERP, it might schedule the file to be send again in a later time.
 
Partner B has the control of which files will accept coming from Partner A. The application must acknowledge incoming files before they are transfered by replying an {{{./rfc5024.html#section-5.3.3}SFID}}.
 
* The Huge Picture
 
[oftp-huge-picture.png] The Huge Picture
 
Now this is the <<huge>> picture. The {{{http://en.wikipedia.org/wiki/Value-added_network}Value-added Network (VAN)}} in the middle is what's more important to note here. In the same session between partner A and the VAN, two or more files can be sent to different partners. This is where the <<Virtual File>> is so important. In it, partner A can set for file Ba that the destination is partner B and do the same thing for Ca. The VAN will look at that information and forward those files correctly to their end destinations. Also, the VAN will forward back to partner A an EERP only when partner B/C send their receipts.

Abstract
 
This memo updates the ODETTE File Transfer Protocol, an established
file transfer protocol facilitating electronic data interchange of
business data between trading partners, to version 2.
 
The protocol now supports secure and authenticated communication over
the Internet using Transport Layer Security, provides file
encryption, signing, and compression using Cryptographic Message
Syntax, and provides signed receipts for the acknowledgement of
received files.
 
The protocol supports both direct peer-to-peer communication and
indirect communication via a Value Added Network and may be used with
TCP/IP, X.25, and ISDN-based networks.

<a name="section-1">1</a>. Introduction
 
<a name="section-1.1">1.1</a>. Background
 
The ODETTE File Transfer Protocol (ODETTE-FTP) was defined in 1986 by
working group four of the Organisation for Data Exchange by Tele
Transmission in Europe (ODETTE) to address the electronic data
interchange (EDI) requirements of the European automotive industry.
 
ODETTE-FTP allows business applications to exchange files on a peer-
to-peer basis in a standardised, purely automatic manner and provides
a defined acknowledgement process on successful receipt of a file.
 
ODETTE-FTP is not to be confused as a variant of, or similar to, the
Internet FTP [<a href="#ref-FTP">FTP</a>], which provides an interactive means for
individuals to share files and which does not have any sort of
acknowledgement process. By virtue of its interactive nature, lack
of file acknowledgements, and client/server design, FTP does not
easily lend itself to mission-critical environments for the exchange
of business data.
 
Over the last ten years, ODETTE-FTP has been widely deployed on
systems of all sizes from personal computers to large mainframes
while the Internet has emerged as the dominant international network,
providing high-speed communication at low cost. To match the demand
for EDI over the Internet, ODETTE has decided to extend the scope of
its file transfer protocol to incorporate security functions and
advanced compression techniques to ensure that it remains at the
forefront of information exchange technology.
 
The protocol now supports secure and authenticated communication over
the Internet using Transport Layer Security, provides file
encryption, signing, and compression using Cryptographic Message
Syntax, and provides signed receipts for the acknowledgement of
received files.
 
The protocol supports both direct peer-to-peer communication and
indirect communication via a Value Added Network and may be used with
TCP/IP, X.25 and ISDN based networks.
 
ODETTE-FTP has been defined by the ODETTE Security Working Group
which consists of a number of ODETTE member organisations. All
members have significant operational experience working with and
developing OFTP and EDI solutions.

<a name="section-1.2">1.2</a>. Summary of Features
 
This memo is a development of version 1.4 of ODETTE-FTP [<a href="#ref-OFTP">OFTP</a>] with
these changes/additions:
 
Session level encryption
File level encryption
Secure authentication
File compression
Signed End to End Response (EERP)
Signed Negative End Response (NERP)
Maximum permitted file size increased to 9 PB (petabytes)
Virtual file description added
Extended error codes
 
Version 1.4 of ODETTE-FTP included these changes and additions to
version 1.3:
 
Negative End Response (NERP)
Extended Date and Time stamp
New reason code 14 (File direction refused)
 
<a name="section-1.3">1.3</a>. General Principles
 
The aim of ODETTE-FTP is to facilitate the transmission of a file
between one or more locations in a way that is independent of the
data communication network, system hardware, and software
environment.
 
In designing and specifying the protocol, the following factors were
considered.
 
<a name="section-1">1</a>. The possible differences of size and sophistication of file
storage and small and large systems.
 
<a name="section-2">2</a>. The necessity to work with existing systems (reduce changes to
existing products and allow easy implementation).
 
<a name="section-3">3</a>. Systems of different ages.
 
<a name="section-4">4</a>. Systems of different manufactures.
 
<a name="section-5">5</a>. The potential for growth in sophistication (limit impact and avoid
changes at other locations).

<a name="section-1.4">1.4</a>. Structure
 
ODETTE-FTP is modelled on the OSI reference model. It is designed to
use the Network Service provided by level 3 of the model and provide
a File Service to the users. Thus, the protocol spans levels 4 to 7
of the model.
 
The description of ODETTE-FTP contained in this memo is closely
related to the original 'X.25' specification of the protocol and in
the spirit of the OSI model describes:
 
<a name="section-1">1</a>. A File Service provided to a User Monitor.
 
<a name="section-2">2</a>. A protocol for the exchange of information between peer
ODETTE-FTP entities.
 
<a name="section-1.5">1.5</a>. Virtual Files
 
Information is always exchanged between ODETTE-FTP entities in a
standard representation called a Virtual File. This allows data
transfer without regard for the nature of the communicating systems.
 
The mapping of a file between a local and virtual representation will
vary from system to system and is not defined here.

A Virtual File is described by a set of attributes identifying and
defining the data to be transferred. The main attributes are
detailed in Sections 1.5.1 to 1.5.4.
 
<a name="section-1.5.1">1.5.1</a>. Organisation
 
Sequential
 
Logical records are presented one after another. ODETTE-FTP must
be aware of the record boundaries.
 
<a name="section-1.5.2">1.5.2</a>. Identification

Dataset name of the Virtual File being transferred, assigned by
bilateral agreement.

<a href="http://ietfdocs.potaroo.net/idref/rfc5024">RFC 5024</a> ODETTE FTP 2 November 2007
 
 
Time stamp (HHMMSScccc)
 
A file qualifier indicating the time the Virtual File was made
available for transmission. The counter (cccc=0001-9999) gives
higher resolution.
 
Date stamp (CCYYMMDD)
 
A file qualifier indicating the date the Virtual File was made
available for transmission.
 
The Dataset Name, Date, and Time attributes are assigned by the
Virtual File's originator and are used to uniquely identify a file.
They are all mandatory and must not be changed by intermediate
locations.
 
The User Monitor may use the Virtual File Date and Time attributes in
local processes involving date comparisons and calculations. Any
such use falls outside the scope of this protocol.
 
<a name="section-1.5.3">1.5.3</a>. Record Format
 
Four record formats are defined:
 
Fixed (F)
 
Each record in the file has the same length.
 
Variable (V)
 
The records in the file can have different lengths.
 
Unstructured (U)
 
The file contains a stream of data. No structure is defined.
 
Text File (T)
 
A Text File is defined as a sequence of ASCII characters,
containing no control characters except CR-LF that delimit
lines. A line will not have more than 2048 characters.
 
<a name="section-1.5.4">1.5.4</a>. Restart
 
ODETTE-FTP can negotiate the restart of an interrupted Virtual File
transmission. Fixed and Variable format files are restarted on
record boundaries. For Unstructured and Text files, the restart
position is expressed as a file offset in 1K (1024 octet) blocks.

<a name="page-9"> </a>
<a href="http://ietfdocs.potaroo.net/idref/rfc5024">RFC 5024</a> ODETTE FTP 2 November 2007
 
 
The restart position is always calculated relative to the start of
the Virtual File.
 
<a name="section-1.6">1.6</a>. Service Description
 
ODETTE-FTP provides a file transfer service to a User Monitor and in
turn uses the Internet transport layer stream service to communicate
between peers.
 
These services are specified in this memo using service primitives
grouped into four classes as follows:
 
Request (RQ) An entity asks the service to do some work.
Indication (IND) A service informs an entity of an event.
Response (RS) An entity responds to an event.
Confirm (CF) A service informs an entity of the response.
 
Services may be confirmed, using the request, indication, response,
and confirm primitives, or unconfirmed using just the request and
indication primitives.
 
<a name="section-1.7">1.7</a>. Security
 
ODETTE-FTP provides a number of security services to protect a
Virtual File transmission across a hostile network.
 
These security services are as follows:
 
Confidentiality
Integrity
Non-repudiation of receipt
Non-repudiation of origin
Secure authentication
 
Security services in this specification are implemented as follows:
 
Session level encryption
File level encryption
Signed files
Signed receipts
Session level authentication
ODETTE-FTP Authentication
 
Session level encryption provides data confidentiality by encryption
of all the protocol commands and data exchanged between two parties,
preventing a third party from extracting any useful information from
the transmission.
 
 
 
 
Friend Informational [Page 9]
<a name="page-10"> </a>
<a href="http://ietfdocs.potaroo.net/idref/rfc5024">RFC 5024</a> ODETTE FTP 2 November 2007
 
 
This session level encryption is achieved by layering ODETTE-FTP over
Transport Layer Security [<a href="#ref-TLS">TLS</a>], distinguishing between secure and
unsecure TCP/IP traffic using different port numbers.
 
File encryption provides complementary data confidentiality by
encryption of the files in their entirety. Generally, this
encryption occurs prior to transmission, but it is also possible to
encrypt and send files while in session. File encryption has the
additional benefit of allowing a file to remain encrypted outside of
the communications session in which it was sent. The file can be
received and forwarded by multiple intermediaries, yet only the final
destination will be able to decrypt the file. File encryption does
not encrypt the actual protocol commands, so trading partner EDI
codes and Virtual File names are still viewable.
 
Secure authentication is implemented through the session level
authentication features available in [<a href="#ref-TLS">TLS</a>] and proves the identity of
the parties wishing to communicate.
 
ODETTE-FTP Authentication also provides an authentication mechanism,
but one that is integral to ODETTE-FTP and is available on all
network infrastructures over which ODETTE-FTP is operated (this is in
contrast to [<a href="#ref-TLS">TLS</a>] which is generally only available over TCP/IP-based
networks). Both parties are required to possess certificates when
ODETTE-FTP Authentication is used.
 
The security features in ODETTE-FTP 2 are centred around the use of
[<a href="#ref-X.509">X.509</a>] certificates. To take advantage of the complete range of
security services offered in both directions, each party is required
to possess an [<a href="#ref-X.509">X.509</a>] certificate. If the confidentiality of data
between two parties is the only concern, then [<a href="#ref-TLS">TLS</a>] alone can be
used, which allows the party accepting an incoming connection (the
Responder) to be the only partner required to possess a certificate.
 
For businesses, this means that session level encryption between a
hub and its trading partners can be achieved without requiring all
the trading partners to obtain a certificate, assuming that trading
partners always connect to the hub.
 
With the exception of [<a href="#ref-TLS">TLS</a>], all the security services work with X.25
and ISDN as transport media. Although nothing technically precludes
[<a href="#ref-TLS">TLS</a>] from working with X.25 or ISDN, implementations are rare.

<a name="section-2">2</a>. Network Service
 
<a name="section-2.1">2.1</a>. Introduction
 
ODETTE-FTP peer entities communicate with each other via the OSI
Network Service or the Transmission Control Protocol Transport
Service [<a href="#ref-RFC793">RFC793</a>]. This is described by service primitives
representing request, indication, response, and confirmation actions.
 
For the Internet environment, the service primitives mentioned below
for the Network Service have to be mapped to the respective Transport
Service primitives. This section describes the Network Service
primitives used by ODETTE-FTP and their relationship to the TCP
interface. In practice, the local transport service application
programming interface will be used to access the TCP service.
 
<a name="section-2.2">2.2</a>. Service Primitives
 
All network primitives can be directly mapped to the respective
Transport primitives when using TCP.
 
<a name="section-2.2.1">2.2.1</a>. Network Connection
 
N_CON_RQ ------&gt; N_CON_IND
N_CON_CF &lt;------ N_CON_RS
 
This describes the setup of a connection. The requesting ODETTE-FTP
peer uses the N_CON_RQ primitive to request an active OPEN of a
connection to a peer ODETTE-FTP, the Responder, which has previously
requested a passive OPEN. The Responder is notified of the incoming
connection via N_CON_IND and accepts it with N_CON_RS. The requester
is notified of the completion of its OPEN request upon receipt of
N_CON_CF.
 
Parameters

<a name="section-2.2.2">2.2.2</a>. Network Data
 
N_DATA_RQ ------&gt; N_DATA_IND
 
Data exchange is an unconfirmed service. The requester passes data
for transmission to the Network Service via the N_DATA_RQ primitive.
The Responder is notified of the availability of data via N_DATA_IND.

In practice, the notification and receipt of data may be combined,
such as by the return from a blocking read from the network socket.
 
Parameters

Data ------------------&gt; same
 
<a name="section-2.2.3">2.2.3</a>. Network Disconnection
 
N_DISC_RQ ------&gt; N_DISC_IND
 
An ODETTE-FTP requests the termination of a connection with the
N_DISC_RQ service primitive. Its peer is notified of the CLOSE by a
N_DISC_IND event. It is recognised that each peer must issue a
N_DISC_RQ primitive to complete the TCP symmetric close procedure.
 
<a name="section-2.2.4">2.2.4</a>. Network Reset
 
------&gt; N_RST_IND
 
An ODETTE-FTP entity is notified of a network error by a N_RST_IND
event. It should be noted that N_RST_IND would also be generated by
a peer RESETTING the connection, but this is ignored here as N_RST_RQ
is never sent to the Network Service by ODETTE-FTP.
 
<a name="section-2.3">2.3</a>. Secure ODETTE-FTP Session
 
[<a name="ref-TLS">TLS</a>] provides a mechanism for securing an ODETTE-FTP session over
the Internet or a TCP network. ODETTE-FTP is layered over [<a href="#ref-TLS">TLS</a>],
distinguishing between secure and unsecure traffic by using different
server ports.
 
The implementation is very simple. Layer ODETTE-FTP over [<a href="#ref-TLS">TLS</a>] in
the same way as layering ODETTE-FTP over TCP/IP. [<a href="#ref-TLS">TLS</a>] provides both
session encryption and authentication, both of which may be used by
the connecting parties. A party acts as a [<a href="#ref-TLS">TLS</a>] server when
receiving calls and acts as a [<a href="#ref-TLS">TLS</a>] client when making calls. When
the [<a href="#ref-TLS">TLS</a>] handshake has completed, the responding ODETTE-FTP may
start the ODETTE-FTP session by sending the Ready Message.
 
<a name="section-2.4">2.4</a>. Port Assignment
 
An ODETTE-FTP requester will select a suitable local port.
 
The responding ODETTE-FTP will listen for connections on Registered
Port 3305; the service name is 'odette-ftp'.

The responding ODETTE-FTP will listen for secure TLS connections on
Registered Port 6619; the service name is 'odette-ftps'.
 
<a name="section-3">3</a>. File Transfer Service
 
The File Transfer Service describes the services offered by an
ODETTE-FTP entity to its User Monitor (generally an application).
 
NOTE: The implementation of the service primitives is an application
issue.

Note: Unlike other commands, where the F_XXX_CF signal is a result of
a corresponding F_XXX_RS command, in this case, the local entity

In a positive Close File response (F_CLOSE_FILE_RS(+)) the current
Listener may either:
 
<a name="section-1">1</a>. Set Speaker to "Yes" and become the Speaker or
2. Set Speaker to "No" and remain the Listener.
 
The File Transfer service will ensure that the setting of the speaker
parameter is consistent with the capabilities of the peer user.
 
The turn is never exchanged in the case of a negative response or
confirmation.
 
Only the Speaker is allowed to issue F_XXX_FILE_RQ primitives.

<a name="section-3.3.4.1">3.3.4.1</a>. Initial Turn (First Speaker)

Responder).
 
<a name="section-3.3.4.2">3.3.4.2</a>. Following Turns
 
Rules:
 
<a name="section-1">1</a>. At each unsuccessful End of File, the turn is not exchanged.
 
<a name="section-2">2</a>. At each successful End of File, the turn is exchanged if requested
by the Listener:
 
- The current Listener receives F_CLOSE_FILE_IND (Speaker =
choice).
 
- If the Listener answers F_CLOSE_FILE_RS(Speaker = YES), it
becomes the Speaker, the Speaker receives F_CLOSE_FILE_CF
(Speaker = NO) and becomes the Listener.
 
- If the Listener answers F_CLOSE_FILE_RS(Speaker = NO), it
remains as the Listener, and the Speaker receives
F_CLOSE_FILE_CF (Speaker = YES) and remains as the Speaker.
 
<a name="section-3">3</a>. The Speaker can issue a Change Direction request (F_CD_RQ) to
become the Listener. The Listener receives a Change Direction
indication (F_CD_IND) and becomes the Speaker.
 
<a name="section-4">4</a>. In order to prevent loops of F_CD_RQ/IND, the Speaker may not send
an F_CD_RQ after receiving an unsolicited F_CD_IND. If the
Listener receives a solicited F_CD_IND as a result of sending
EFPA(Speaker=Yes), it is acceptable to immediately relinquish the
right to speak by sending an F_CD_RQ.
 
<a name="section-3.3.5">3.3.5</a>. End to End Response
 
This service is initiated by the current Speaker (if there is no file

date ---------------&gt; same
time ---------------&gt; same
destination --------&gt; same
originator ---------&gt; same
hash ---------------&gt; same
signature ----------&gt; same
------------------------------------
 
Relationship with Turn:
 
- Only the Speaker may send an End to End Response request.
 
- Invoking the EERP service does not change the turn.
 
- If an F_CD_IND has been received just before F_EERP_RQ is issued,
this results in leaving the special condition created by the
reception of F_CD_IND; i.e., while it was possible to issue
F_RELEASE_RQ and not possible to issue F_CD_RQ just after the
reception of F_CD_IND, after having issued F_EERP_RQ the normal
Speaker status is entered again (F_CD_RQ valid, but F_RELEASE_RQ
not valid).
 
Notes:
 
<a name="section-1">1</a>. The F_EERP_RQ (and also F_NERP_RQ) is confirmed with an F_RTR_CF
signal. The F_RTR_CF signal is common to both F_EERP_RQ and
F_NERP_RQ. There should be no ambiguity, since there can only be
one such request pending at any one time.
 
<a name="section-2">2</a>. The signature is optional and is requested when sending the
F_START_FILE_RQ.
 
<a name="section-3">3</a>. If it is not possible to sign the EERP, then an unsigned EERP
should still be sent.

<a name="section-4">4</a>. It is an application implementation issue to validate the contents
of the EERP and its signature and to decide what action to take on
receipt of an EERP that fails validation or is not signed when a
signed EERP was requested.
 
<a name="section-3.3.6">3.3.6</a>. Negative End Response
 
This service is initiated by the current speaker (if there is no file
transfer in progress) to send a Negative End Response when a file
could not be transmitted to the next destination. It is sent only if
the problem is of a non-temporary kind.
 
This service may also be initiated by the final destination instead
of sending an End to End Response when a file could not be processed,
after having successfully received the file.

<a name="section-4">4</a>. Protocol Specification
 
<a name="section-4.1">4.1</a>. Overview
 
ODETTE-FTP is divided into five operating phases.
 
Start Session
Start File
Data Transfer
End File
End Session
 
After the End File phase, an ODETTE-FTP entity may enter a new Start
File phase or terminate the session via the End Session phase.
 
ODETTE-FTP peers communicate by sending and receiving messages in
Exchange Buffers via the Network Service. Each Exchange Buffer
contains one of the following commands.
 
SSRM Start Session Ready Message
SSID Start Session
SECD Security Change Direction
AUCH Authentication Challenge
AURP Authentication Response
SFID Start File
SFPA Start File Positive Answer
SFNA Start File Negative Answer
DATA Data
CDT Set Credit
EFID End File
EFPA End File Positive Answer
EFNA End File Negative Answer
ESID End Session
CD Change Direction
EERP End to End Response
NERP Negative End Response
RTR Ready To Receive
 
The remainder of this section describes the protocol flows. Section
five details the command formats.
 
<a name="section-4.2">4.2</a>. Start Session Phase
 
The Start Session phase is entered immediately after the network
connection has been established.

<a name="section-4.2.1">4.2.1</a>. Entity Definition
 
The ODETTE-FTP entity that took the initiative to establish the
network connection becomes the Initiator. Its peer becomes the
Responder.
 
<a name="section-4.2.2">4.2.2</a>. Protocol Sequence
 
The first message must be sent by the Responder.
 
<a name="section-1">1</a>. Initiator &lt;-------------SSRM -- Responder Ready Message
-- SSID ------------&gt; Identification
&lt;------------ SSID -- Identification
 
<a name="section-4.2.3">4.2.3</a>. Secure Authentication
 
Having exchanged SSIDs, the Initiator may optionally begin an
authentication phase, in which each party proves its identity to the
other.
 
<a name="section-4.2.4">4.2.4</a>. Protocol Sequence
 
The first authentication message must be sent by the Initiator.
 
<a name="section-1">1</a>. Initiator -- SECD ------------&gt; Responder Change Direction
&lt;------------ AUCH -- Challenge
-- AURP ------------&gt; Response
&lt;------------ SECD -- Change Direction
-- AUCH ------------&gt; Challenge
&lt;------------ AURP -- Response
 
The Initiator sends a Security Change Direction (SECD) to which the
Responder replies with an Authentication Challenge (AUCH).
 
The Responder looks up the public certificate that is linked to the
purported identity of the Initiator (located in the SSID). If the
Responder is unable to locate a suitable certificate then
authentication fails. The Responder uses the public key contained in
the certificate to encrypt a random challenge, unique for each
session, for the Initiator. This encrypted challenge is sent as a
[<a href="#ref-CMS">CMS</a>] envelope to the Initiator as part of the AUCH.
 
The Initiator decrypts the challenge using their private key and
sends the decrypted challenge back to the Responder in the
Authentication Response (AURP).
 
The Responder checks that the data received in the AURP matches the
random challenge that was sent to the Initiator.

<a href="http://ietfdocs.potaroo.net/idref/rfc5024">RFC 5024</a> ODETTE FTP 2 November 2007
 
 
If the data matches, then the Initiator has authenticated
successfully and the Responder replies with a Security Change
Direction (SECD) beginning the complementary process of verifying the
Responder to the Initiator. If the data does not match, then the
Initiator fails authentication.
 
<a name="section-4.3">4.3</a>. Start File Phase
 
<a name="section-4.3.1">4.3.1</a>. Entity Definition
 
The Initiator from the Start Session phase is designated the Speaker
while the Responder becomes the Listener. The roles are reversed by
the Speaker sending a Change Direction command to the Listener.
 
<a name="section-4.3.2">4.3.2</a>. Protocol Sequence
 
<a name="section-1">1</a>. Speaker -- SFID ------------&gt; Listener Start File
&lt;------------ SFPA -- Answer YES
 
<a name="section-2">2</a>. Speaker -- SFID ------------&gt; Listener Start File

Note: The User Monitor should take steps to prevent a loop
situation occurring.

<a name="section-4.3.3">4.3.3</a>. Restart Facilities
 
The Start File command includes a count allowing the restart of an

<a name="section-4.3.4">4.3.4</a>. Broadcast Facilities
 
The destination in a Start File command can be specified as follows.
 
<a name="section-1">1</a>. An explicitly defined destination.
 
<a name="section-2">2</a>. A group destination that allows an intermediate location to
broadcast the Virtual File to multiple destinations.

<a name="page-31"> </a>
<a href="http://ietfdocs.potaroo.net/idref/rfc5024">RFC 5024</a> ODETTE FTP 2 November 2007
 
 
The Listener will send a negative answer to the Speaker when the
destination is not known.
 
<a name="section-4.3.5">4.3.5</a>. Priority
 
The prioritisation of files for transmission is left to the local
implementation. To allow some flexibility, a change direction
mechanism is available in the End File phase.
 
<a name="section-4.3.6">4.3.6</a>. End to End Response (EERP)
 
The End to End Response (EERP) command notifies the originator of a
Virtual File that the Virtual File has been successfully delivered to
its final destination. This allows the originator to perform house
keeping tasks such as deleting copies of the delivered data.
 
If the originator of the Virtual File requested a signed EERP in the
SFID, the EERP must be signed. Signing allows the originator of the
file to prove that the EERP was generated by the final destination.
If the final destination is unable to sign the EERP, it may send back
an unsigned EERP. It is an implementation issue to allow the
acceptance of an unsigned EERP if a signed EERP is requested.
 
A Response Command must be sent from the location performing the
final processing or distribution of the data to the originator. The
Response is mandatory and may be sent in the same or in any
subsequent session.
 
When an intermediate location broadcasts or distributes a Virtual
File, it must receive a Response command from all the locations to
which it forwarded the data before sending its own Response. This
ensures that the Response received by the Virtual File's originator
accounts for all the destination locations. An intermediate location
therefore needs to track the status of files it processes over time.
 
The requesting of a signed EERP is incompatible with the use of
broadcast facilities because an EERP can be signed by only one
destination. If this scenario occurs, the intermediate broadcast
location may continue and ignore the request for a signed EERP or
send back a NERP.
 
Example: Point to Point
 
Location A sends file Ba to location B, which will send an EERP to
location A after it successfully receives the file.

Example: Data distribution
 
Location A sends a Virtual File containing data for distribution
to locations B and C via clearing centres E1 and E2. Clearing
centre E1 must wait for a response from E2 (for file Ba) and
location C before it sends its response, R8, to location A.
Clearing centre E2 can only send response R7 to E1 when location B
acknowledges file Ba with response R6.

Example: Data collection
 
Locations A and B send files Ca and Cb to clearing centre E1,
which forwards both files to location C in a single Virtual File.

response R5 to location A and R6 to location B.

<a name="section-4.3.7">4.3.7</a>. Negative End Response (NERP)
 
In addition to the EERP, which allows control over successful
transmission of a file, a Negative End Response signals that a file
could not be delivered to the final destination or that the final
destination could not process the received file.
 
It may be created by an intermediate node that could not transmit the
file any further because the next node refuses to accept the file.
The cause of the refusal has to be non-temporary, otherwise the
intermediate node has to try the transmission again.
 
It may also be created by the final node that is unable to process
the file because of non-recoverable syntax or semantic errors in the
file, or because of the failure of any other processing performed on
the file.
 
The NERP will be sent back to the originator of the file.
 
The parameters are equal to the ones of the EERP, but with additional
information about the creator of the NERP and the abort reason.
Where the NERP is created due to a failure to transmit, the abort
reason is taken from the refusal reason that was sent by the node
refusing the file. Because of the NERP, it is possible for the
intermediate node to stop trying to send the non-deliverable file and
to delete the file.
 
The NERP allows the originator of the file to react to the
unsuccessful transmission or processing, depending on the reason code
and the creator of the NERP.
 
If the originator of the Virtual File requested a signed EERP in the
SFID, the NERP must be signed. Signing allows the originator of the
file to prove by whom the NERP was generated. If the location

unsigned NERP. It is an implementation issue to allow the acceptance
of an unsigned EERP if a signed NERP is requested.
 
<a name="section-4.3.8">4.3.8</a>. Ready To Receive Command (RTR)
 
In order to avoid congestion between two adjacent nodes caused by a
continuous flow of EERPs and NERPs, a Ready To Receive (RTR) command
is provided. The RTR acts as an EERP/NERP acknowledgement for flow
control but has no end-to-end significance.

To avoid congestion at the protocol level, a flow control mechanism
is provided via the Set Credit (CDT) command.
 
A Credit limit is negotiated in the Start Session phase; this
represents the number of Data Exchange Buffers that the Speaker may
send before it is obliged to wait for a Credit command from the
Listener.
 
The available credit is initially set to the negotiated value by the
Start File positive answer, which acts as an implicit Credit command.
The Speaker decreases the available credit count by one for each data
buffer sent to the Listener.

Error detection and handling should be done as close as possible to
the problem. This aids problem determination and correction. Each
layer of the reference model is responsible for its own error
handling.
 
ODETTE-FTP can detect protocol errors by virtue of its state machine
and uses activity timers to detect session hang conditions. These
mechanisms are separate from the End to End controls.
 
<a name="section-4.7.1">4.7.1</a>. Protocol Errors
 
If a protocol error occurs, the session will be terminated and
application activity aborted. Both locations enter the IDLE state.
 
<a name="section-4.7.2">4.7.2</a>. Timers
 
To protect against application and network hang conditions, ODETTE-
FTP uses activity timers for all situations where a response is
required. The timers and actions to be taken if they expire are
described in <a href="#section-9">Section 9</a>, "Protocol State Machine".
 
<a name="section-4.7.3">4.7.3</a>. Clearing Centres
 
The use of clearing centres introduces the possibility of errors
occurring as a result of data processing activities within the
centre. Such errors are not directly related to ODETTE-FTP or the
communication network and are therefore outside the scope of this
specification.

ODETTE-FTP entities communicate via Exchange Buffers. The Command
Exchange Buffers are described below. Virtual File data is carried
in Data Exchange Buffers, which are described in <a href="#section-7">Section 7</a>.
 
<a name="section-5.1">5.1</a>. Conventions
 
<a name="section-5.1.1">5.1.1</a>. Representation Unit
 
The basic unit of information is an octet, containing 8 bits.
 
<a name="section-5.1.2">5.1.2</a>. Values and Characters
 
The ISO 646 IRV 7-bit coded character set [<a href="#ref-ISO-646">ISO-646</a>], according to
Appendix B, is used to encode constants and strings within Command
Exchange Buffers except where [<a href="#ref-UTF-8">UTF-8</a>] is explicitly indicated against
a field.
 
<a name="section-5.2">5.2</a>. Commands
 
A Command Exchange Buffer contains a single command starting at the
beginning of the buffer. Commands and data are never mixed within an
Exchange Buffer. Commands cannot be compressed. Variable-length
parameters may be omitted entirely if not required and the associated
length indicator field set to zero.
 
Components:
 
<a name="section-1">1</a>. Command identifier:
 
The first octet of an Exchange Buffer is the Command Identifier
and defines the format of the buffer.
 
<a name="section-2">2</a>. Parameter(s):
 
Command parameters are stored in fields within a Command Exchange
Buffer. Where variable-length fields are used, they are preceded
with a header field indicating the length. All values are
required except where explicitly indicated.

SFIDFMT File Format Character
 
Value: 'F' Fixed format binary file
'V' Variable format binary file
'U' Unstructured binary file
'T' Text
 
Virtual File format. Used to calculate the restart
position (<a href="#section-1.5.4">Section 1.5.4</a>).
 
Once a file has been signed, compressed, and/or encrypted,
in file format terms it becomes unstructured, format U.
The record boundaries are no longer discernable until the
file is decrypted, decompressed, and/or verified. SFID
File Format Field in this scenario indicates the format of
the original file, and the transmitted file must be treated
as U format.
 
SFIDLRECL Maximum Record Size Numeric(5)
 
Maximum: 99999
 
Length in octets of the longest logical record that may be
transferred to a location. Only user data is included.
 
If SFIDFMT is 'T' or 'U', then this attribute must be set
to '00000'.
 
If SFIDFMT is 'V' and the file is compressed, encrypted, or
signed, then the maximum value of SFIDRECL is '65536'.
 
SFIDFSIZ Transmitted File Size Numeric(13)
 
Maximum: 9999999999999
 
Space in 1K (1024 octet) blocks required at the Originator
location to store the actual Virtual File that is to be
transmitted.
 
For example, if a file is compressed before sending, then
this is the space required to store the compressed file.
 
This parameter is intended to provide only a good estimate
of the Virtual File size.
 
Using 13 digits allows for a maximum file size of
approximately 9.3 PB (petabytes) to be transmitted.

SFIDOSIZ Original File Size Numeric(13)
 
Maximum: 9999999999999
 
Space in 1K (1024 octet) blocks required at the Originator
location to store the original before it was signed,
compressed, and/or encrypted.
 
If no security or compression services have been used,
SFIDOSIZ should contain the same value as SFIDFSIZ.
 
If the original file size is not known, the value zero
should be used.
 
This parameter is intended to provide only a good estimate
of the original file size.
 
The sequence of events in file exchange are:
 
(a) raw data file ready to be sent
SFIDOSIZ = Original File Size
 
(b) signing/compression/encryption
 
(c) transmission
SFIDFSIZ = Transmitted File Size
 
(d) decryption/decompression/verification
 
(e) received raw data file for in-house applications
SFIDOSIZ = Original File Size
 
The Transmitted File Size at (c) indicates to the receiver
how much storage space is needed to receive the file.
 
The Original File Size at (e) indicates to the in-house
application how much storage space is needed to process the
file.

SFIDREST Restart Position Numeric(17)
 
Maximum: 99999999999999999
 
Virtual File restart position.
 
The count represents the:
- Record Number if SSIDFMT is 'F' or 'V'.
- File offset in 1K (1024 octet) blocks if SFIDFMT is
'U' or 'T'.
 
The count will express the transmitted user data (i.e.,
before ODETTE-FTP buffer compression, header not included).
 
After negotiation between adjacent locations,
retransmission will start at the lowest value.
 
Once a file has been signed, compressed, and/or encrypted,
in file format terms, it has become unstructured, like
format U. The file should be treated as format U for the
purposes of restart, regardless of the actual value in
SFIDFMT.
 
SFIDSEC Security Level Numeric(2)
 
Value: '00' No security services
'01' Encrypted
'02' Signed
'03' Encrypted and signed
 
Indicates whether the file has been signed and/or encrypted
before transmission. (See <a href="#section-6.2">Section 6.2</a>.)
 
SFIDCIPH Cipher suite selection Numeric(2)
 
Value: '00' No security services
'01' See <a href="#section-10.2">Section 10.2</a>
 
Indicates the cipher suite used to sign and/or encrypt the
file and also to indicate the cipher suite that should be
used when a signed EERP or NERP is requested.

Value: '0' No compression
'1' Compressed with [<a href="#ref-ZLIB">ZLIB</a>] algorithm
 
Indicates the algorithm used to compress the file.
(See <a href="#section-6.4">Section 6.4</a>.)
 
SFIDENV File enveloping format Numeric(1)
 
Value: '0' No envelope
'1' File is enveloped using [<a href="#ref-CMS">CMS</a>]
 
Indicates the enveloping format used in the file.
 
If the file is encrypted/signed/compressed or is an
enveloped file for the exchange and revocation of
certificates, this field must be set accordingly.
 
SFIDSIGN Signed EERP request Character
 
Value: 'Y' The EERP returned in acknowledgement of the file
must be signed
'N' The EERP must not be signed
 
Requests whether the EERP returned for the file must be
signed.
 
SFIDDESCL Virtual File Description length Numeric(3)
 
Length in octets of the field SFIDDESC.
 
A value of 0 indicates that no description is present.
 
SFIDDESC Virtual File Description [<a href="#ref-UTF-8">UTF-8</a>](n)
 
May be used by ODETTE-FTP in any way. If not used,
SFIDDESCL should be set to zero.
 
No general structure is defined for this attribute, but it
is expected that a bilateral agreement exists as to the
meaning of the data.
 
It is encoded using [<a href="#ref-UTF-8">UTF-8</a>] to support a range of national

'99' Unspecified reason.
 
Reason why transmission cannot proceed.
 
SFNARRTR Retry Indicator Character
 
Value: 'N' Transmission should not be retried.
'Y' The transmission may be retried later.
 
This parameter is used to advise the Speaker if it should
retry at a later time due to a temporary condition at the
Listener site, such as a lack of storage space. It should
be used in conjunction with the Answer Reason code
(SFNAREAS).
 
An invalid file name error code may be the consequence of a
problem in the mapping of the Virtual File on to a real
file. Such problems cannot always be resolved immediately.
It is therefore recommended that when an SFNA with Retry =
Y is received the User Monitor attempts to retransmit the
relevant file in a subsequent session.

<a name="section-6">6</a>. File Services
 
<a name="section-6.1">6.1</a>. Overview
 
ODETTE-FTP provides services for compressing, encrypting, and signing
files. These services should generally be performed off line,
outside of the ODETTE-FTP communications session for performance
reasons, although this is not a strict requirement.
 
ODETTE-FTP requires that the following steps must be performed in
this exact sequence, although any of steps 2, 3, or 4 may be omitted.
Step 1 is required only if any of steps 2, 3, or 4 are performed:
 
<a name="section-1">1</a>. Insert record length indicators (V format files only; see Section
6.5)
2. Sign
3. Compress
4. Encrypt
 
The cipher suite for the encryption and signing algorithms is
assigned by bilateral agreement.
 
Secured and/or compressed files must be enveloped. The envelope
contains additional information about the service used that is
necessary for a receiving party to fully process the file.
 
The [<a href="#ref-CMS">CMS</a>] content types used are:
 
EnvelopedData - Indicates encrypted data
CompressedData - Indicates compressed data
SignedData - Indicates signed content
Data - Indicates unstructured data
 
For signed or encrypted data, the encapsulated content type
(eContentType field) is id-data.
 
<a name="section-6.2">6.2</a>. File Signing
 
Files that are to be signed are enveloped according to the file
enveloping format (SFIDENV). Generally, this will be as a [<a href="#ref-CMS">CMS</a>]
package.
 
A file may be signed more than once to ease the changeover between
old and new certificates.
 
 
 
 
 
 
 
Friend Informational [Page 69]
<a name="page-70"> </a>
<a href="http://ietfdocs.potaroo.net/idref/rfc5024">RFC 5024</a> ODETTE FTP 2 November 2007
 
 
It is recommended that the envelope does not contain the public
certificate of the signer. Where files are sent to the same
recipient continuously, it would serve no benefit to repeatedly send
the same certificate. Both the original file data and signature are
stored within the [<a href="#ref-CMS">CMS</a>] package.
 
<a name="section-6.3">6.3</a>. File Encryption
 
Files that are to be encrypted are enveloped according to the file
enveloping format (SFIDENV). Generally, this will be as a [<a href="#ref-CMS">CMS</a>]
package.
 
It is recommended that encryption should be performed before the
ODETTE-FTP session starts because a large file takes a long time to
encrypt and could cause session time outs, even on high-performance
machines.
 
Likewise, decryption of the file should occur outside of the session.
However, an application may choose to allow in-session encryption and
decryption for very small files.
 
<a name="section-6.4">6.4</a>. File Compression
 
Files that are to be compressed are enveloped according to the file
enveloping format (SFIDENV). Generally, this will be as a [<a href="#ref-CMS">CMS</a>]
package using the [<a href="#ref-CMS-Compression">CMS-Compression</a>] data type, which uses the [<a href="#ref-ZLIB">ZLIB</a>]
compression algorithm by default.
 
Unlike the buffer compression method, this method operates on a whole
file. Because of the increased levels of compression, file level
compression essentially deprecates the older buffer compression
inside ODETTE-FTP. The buffer compression is kept for backwards
compatibility.
 
<a name="section-6.5">6.5</a>. V Format Files - Record Lengths
 
A file that has been signed, compressed, and/or encrypted will have
lost its record structure, so ODETTE-FTP will not be able to insert
the End of Record Flag in subrecord headers in Data Exchange Buffers.
To preserve the record structure, V format files must have record
headers inserted into them prior to signing, compression, or
encryption. These 2-byte binary numbers, in network byte order,
indicate the length of each record, allowing the receiving system,
where appropriate, to recreate the files complete with the original
variable-length records. Note that the header bytes hold the number
of data bytes in the record and don't include themselves.

<a href="http://ietfdocs.potaroo.net/idref/rfc5024">RFC 5024</a> ODETTE FTP 2 November 2007
 
 
This is only applicable to V format files, which themselves are
typically only of concern for mainframes.
 
<a name="section-7">7</a>. ODETTE-FTP Data Exchange Buffer
 
<a name="section-7.1">7.1</a>. Overview
 
Virtual Files are transmitted by mapping the Virtual File records
into Data Exchange Buffers, the maximum length of which was
negotiated between the ODETTE-FTP entities via the Start Session
(SSID) commands exchanged during the Start Session phase of the
protocol.
 
Virtual File records may be of arbitrary length. A simple
compression scheme is defined for strings of repeated characters.
 
An example of the use of the Data Exchange Buffer can be found in
Appendix A.
 
<a name="section-7.2">7.2</a>. Data Exchange Buffer Format
 
For transmission of Virtual File records, data is divided into
subrecords, each of which is preceded by a 1-octet Subrecord Header.
 
The Data Exchange Buffer is made up of the initial Command Character
followed by pairs of Subrecord Headers and subrecords, as follows.
 
o--------------------------------------------------------
| C | H | | H | | H | | /
| M | D | SUBRECORD | D | SUBRECORD | D | SUBRECORD | /_
| D | R | | R | | R | | /

Bits
 
<a name="section-0">0</a> End of Record Flag
 
Set to indicate that the next subrecord is the last
subrecord of the current record.
 
Unstructured files are transmitted as a single record; in
this case, the flag acts as an end-of-file marker.
 
<a name="section-1">1</a> Compression Flag
 
Set to indicate that the next subrecord is compressed.
 
2-7 Subrecord Count
 
The number of octets in the Virtual File represented by the
next subrecord expressed as a binary value.
 
For uncompressed data, this is simply the length of the
subrecord.
 
For compressed data, this is the number of times that the
single octet in the following subrecord must be inserted in
the Virtual File.
 
As 6 bits are available, the next subrecord may represent
between 0 and 63 octets of the Virtual File.
 
<a name="section-7.3">7.3</a>. Buffer Filling Rules
 
A Data Exchange Buffer may be any length up to the value negotiated
in the Start Session exchange.
 
Virtual File records may be concatenated within one Data Exchange
Buffer or split across a number of buffers.
 
A subrecord is never split between two Exchange Buffers. If the
remaining space in the current Exchange Buffer is insufficient to
contain the next 'complete' subrecord, one of the following
strategies should be used:
 
<a name="section-1">1</a>. Truncate the Exchange Buffer, and put the complete subrecord
(preceded by its header octet) in a new Exchange Buffer.
 
<a name="section-2">2</a>. Split the subrecord into two, filling the remainder of the
Exchange Buffer with the first new subrecord and starting a new
Exchange Buffer with the second.

<a name="section-8">8</a>. Stream Transmission Buffer
 
<a name="section-8.1">8.1</a>. Introduction
 
To utilise the TCP stream, a Stream Transmission Buffer (STB) is
created by adding a Stream Transmission Header (STH) to the start of
all Command and Data Exchange Buffers before they are passed to the
TCP transport service. This allows the receiving ODETTE-FTP to
recover the original Exchange Buffers.
 
Note: The Stream Transmission Buffer is not used when using ODETTE-
FTP over an X.25 network.
 
This is because ODETTE-FTP can rely on the fact that the Network
Service will preserve the sequence and boundaries of data units
transmitted through the network and that the Network Service will
pass the length of the data unit to the receiving ODETTE-FTP. TCP
offers a stream-based connection that does not provide these
functions.
 
The Stream Transmission Buffer is composed of an STH and an OEB.

The length of the Stream Transmission Buffer (STH+OEB).
 
The smallest STB is 5 octets consisting of a 4-octet header
followed by a 1-octet Exchange Buffer such as a Change Direction

The maximum Exchange Buffer length that can be negotiated is 99999
octets (<a href="#section-5.3.2">Section 5.3.2</a>) giving an STB length of 100003.
 
The length is expressed as a binary number in network byte order.
 
It is expected that implementations of this protocol will follow the
Internet robustness principle of being conservative in what is sent
and liberal in what is accepted.
 
<a name="section-9">9</a>. Protocol State Machine
 
<a name="section-9.1">9.1</a>. ODETTE-FTP State Machine
 
The operation of an ODETTE-FTP entity is formally defined by the
State Machine presented below. There are five State and Transition
tables, and for each table additional information is given in the
associated Predicate and Action lists.
 
The response of an ODETTE-FTP entity to the receipt of an event is
defined by a Transition table entry indexed by the Event/State
intersection within the appropriate state table.
 
Each Transition table entry defines the actions taken, events
generated, and new state entered. Predicates may be used within a
table entry to select the correct response on the basis of local
information held by the entity.

A Transition table contains the following fields:
 
Index (I) State transition index.
 
Predicate A list of predicates used to select between different
possible transitions. The predicates are defined in
the Predicate and Action lists.
 
Actions A list of actions taken by the entity. The actions are
defined in the Predicate and Action lists.
 
Events Output events generated by the entity.
 
Next State The new state of the entity.
 
<a name="section-9.2">9.2</a>. Error Handling
 
The receipt of an event in a given state may be invalid for three
reasons.
 
<a name="section-1">1</a>. The case is impossible by design of the state automata, denoted
'X' in the state tables. For example, a timer that has not been
set cannot run out.
 
<a name="section-2">2</a>. The event is the result of an error in the Network Service
implementation, also denoted 'X' in the state tables. The
Network Service implementation is considered to be correct.
 
<a name="section-3">3</a>. For all other cases, the event is considered to be a User Error,
denoted "U" in the state tables.
 
The state tables define the conditions under which a User event is
valid, thus preventing the generation of a protocol error by the
ODETTE-FTP entity as a result of a User Monitor error. The reaction
of the entity to such errors is undefined and regarded as a local
implementation issue.
 
The state tables also allow protocol errors due to the receipt of
invalid Exchange Buffers, to be detected. In such cases, the
reaction of the entity to the error is defined.

Note 1: Flow control in case of reception.
 
The ODETTE-FTP Listener must periodically send new
credit to the Speaker. The timing of this operation
will depend on:
 
<a name="section-1">1</a>. The User Monitor's capacity to receive data.
2. The number of buffers available to ODETTE-FTP.
3. The Speaker's available credit, which must be
equal to zero.
 
<a name="section-9.13">9.13</a>. Example
 
Consider an ODETTE-FTP entity that has sent a Start File (SFID)
command and entered the Open Out Pending (OPOP) state. Its response
on receiving a Positive Answer (SFPA) is documented in Speaker State
Table 1, which shows that transition 'K' should be applied and is
interpreted as follows:
 
if (I.SFPA.Restart-pos &gt; V.Restart-pos) then
begin // invalid restart
Actions: Stop inactivity timer, // reset timer
Start inactivity timer;
Output: ESID(R=02), // to peer ODETTE-FTP
F_ABORT_IND(R,AO=L); // to User Monitor
New State: WF_NDISC;
end
else begin
Actions: Stop inactivity timer, // reset timer
Start inactivity timer;
Build F_START_FILE_CF(+) from I.SFPA
V.Credit_S = V.Window // initialise credit
Output: F_START_FILE_CF(+); // to User Monitor
New State: OPO;
end

<a href="http://ietfdocs.potaroo.net/idref/rfc5024">RFC 5024</a> ODETTE FTP 2 November 2007
 
 
ODETTE-FTP checks the restart position in the received Start File
Positive Answer (SFPA) command. If it is invalid, it aborts the
session by sending an End Session (ESID) command to its peer and an
Abort indication (F_ABORT_IND) to its User Monitor. If the restart
position is valid, a Start File confirmation (F_START_FILE_CF) is
built and sent to the User Monitor, the credit window is initialised,
and the Open Out (OPO) state is entered.
 
<a name="section-10">10</a>. Miscellaneous
 
<a name="section-10.1">10.1</a>. Algorithm Choice
 
The choice of algorithms to use for security or compression between
partners is for bilateral agreement outside of ODETTE-FTP.
 
<a name="section-10.2">10.2</a>. Cryptographic Algorithms
 
The algorithms for symmetric and asymmetric cryptography and hashing
are represented by a coded value, the cipher suite:
 
Cipher Suite Symmetric Asymmetric Hashing
------------ ----------------- ------------ -------
 
<a name="section-01">01</a> 3DES_EDE_CBC_3KEY RSA_PKCS1_15 SHA-1
02 AES_256_CBC RSA_PKCS1_15 SHA-1
 
Support of all cipher suites listed here is mandatory.
 
The certificates used must be [<a href="#ref-X.509">X.509</a>] certificates.
 
TripleDES is using Cipher Block Chaining (CBC) mode for added
security and uses the Encryption Decryption Encryption (EDE) process
with 3 different 64-bit keys.
 
RSA padding is as defined in [PKCS#1].
 
AES is using a 256-bit key in CBC mode.
 
An extended list of optional cipher suites may be used (Section
10.3), but there is no guarantee that two communicating ODETTE-FTP
entities would both support these optional cipher suites.
 
<a name="section-10.3">10.3</a>. Protocol Extensions
 
The algorithms and file enveloping formats available in ODETTE-FTP
may be extended outside of this document.
 
 
 
 
 
Friend Informational [Page 97]
<a name="page-98"> </a>
<a href="http://ietfdocs.potaroo.net/idref/rfc5024">RFC 5024</a> ODETTE FTP 2 November 2007
 
 
An up-to-date list of cipher suite values for use in ODETTE-FTP is
maintained by ODETTE International, and published on their website at
www.odette.org.
 
<a name="section-10.4">10.4</a>. Certificate Services
 
Certificates and certificate revocation lists may be exchanged as
[<a href="#ref-CMS">CMS</a>] enveloped files. It is therefore valid to exchange a [<a href="#ref-CMS">CMS</a>]
file that is neither encrypted, compressed, nor signed. It is an
application implementation issue to determine the correct course of
action on receipt of such a file.
 
<a name="section-11">11</a>. Security Considerations
 
ODETTE-FTP security requires the use of [<a href="#ref-X.509">X.509</a>] certificates. If no
security options are agreed for use, the send and receive passwords
are sent in plain text. Whilst this is acceptable over X.25 and ISDN
networks, this is a risky practice over insecure public networks such
as the Internet.
 
All, some, or none of the security options available in ODETTE-FTP
may be used. No recommendations for the use of these options are
provided in this specification. Whilst use of the highest-strength
encryption algorithms may seem admirable, there is often a
performance tradeoff to be made, and signing all files and
acknowledgements has potential legal implications that should be
considered.
 
It should be noted that whilst the security measures ensure that an
ODETTE-FTP partner is authenticated, it does not necessarily mean
that the partner is authorised. Having proven the identity of a
partner, it is an application issue to decide whether that partner is
allowed to connect or exchange files.
 
Extracted from [<a href="#ref-RFC3850">RFC3850</a>]:
 
"When processing certificates, there are many situations where the
processing might fail. Because the processing may be done by a user
agent, a security gateway, or other program, there is no single way
to handle such failures. Just because the methods to handle the
failures have not been listed, however, the reader should not assume
that they are not important. The opposite is true: if a certificate
is not provably valid and associated with the message, the processing
software should take immediate and noticeable steps to inform the end
user about it.
 
 
 
 
 
 
Friend Informational [Page 98]
<a name="page-99"> </a>
<a href="http://ietfdocs.potaroo.net/idref/rfc5024">RFC 5024</a> ODETTE FTP 2 November 2007
 
 
Some of the many situations in which signature and certificate
checking might fail include the following:
 
No certificate chain leads to a trusted CA
No ability to check the Certificate Revocation List (CRL) for a
certificate
An invalid CRL was received
The CRL being checked is expired
The certificate is expired
The certificate has been revoked
 
There are certainly other instances where a certificate may be
invalid, and it is the responsibility of the processing software to
check them all thoroughly, and to decide what to do if the check
fails. See <a href="http://ietfdocs.potaroo.net/idref/rfc3280">RFC 3280</a> for additional information on certificate path
validation."
 
The push / pull nature of ODETTE-FTP means that a party can make an
outbound connection from behind a firewall to another party and
exchange files in both directions. There is no need for both
partners to open ports on their firewalls to allow incoming
connections; only one party needs to allow incoming connections.
 
See <a href="#section-1.7">Section 1.7</a> for a discussion of the benefits of session security
[<a href="#ref-TLS">TLS</a>] versus file security.

Appendix A. Virtual File Mapping Example
 
This example demonstrates the mapping of a Virtual File into a
sequence of ODETTE-FTP Data Exchange Buffers.
 
Each line in this extract from 'The Rime of the Ancient Mariner' by
Coleridge [<a href="#ref-RIME">RIME</a>] is separated by CR-LFs in a file that is being
transmitted as a T format file.
 
It is an ancient Mariner,
And he stoppeth one of three.
"By thy long grey beard and glittering eye,
Now wherefore stopp'st thou me?
 
"The Bridegroom's doors are opened wide,
And I am next of kin;
The guests are met, the feast is set:
May'st hear the merry din."
 
He holds him with his skinny hand,
"There was a ship," quoth he.
"Hold off! unhand me, grey-beard loon!"
Eftsoons his hand dropt he.
 
He holds him with his glittering eye--
The Wedding-Guest stood still,
And listens like a three years; child:
The Mariner hath his will.
 
The Wedding-Guest sat on a stone:
He cannot chuse but hear;
And thus spake on that ancient man,
The bright-eyed Mariner.
 
The ship was cheered, the harbour cleared,
Merrily did we drop
Below the kirk, below the hill,
Below the light-house top.
 
The Exchange Buffers below were built from the above. The top line
of each represents the ASCII code, while the two lines below give the
hexadecimal value.
 
Note that:
 
. The "D" at the beginning of each Exchange Buffer is the command
code.

Appendix C. X.25 Specific Information
 
The International Organization for Standardization (ISO) Open Systems
Interconnection (OSI) model is the basis for ODETTE-FTP.
 
ODETTE-FTP covers levels 4 to 7, and originally CCITT X.25 was the
only recommended telecommunication protocol for OSI's layers 1, 2, 3.
 
ISO Reference Model:
 
+------------------------------+ &lt;==== File Service
| Level-7 FTP application |
|------------------------------|
| Level-6 FTP presentation |
|------------------------------|
| Level-5 FTP session |
|------------------------------|
| Level-4 FTP transport |
|------------------------------| &lt;==== Network Service
| Level-3 X.25 |
|------------------------------|
| Level-2 X.25 |
|------------------------------|
| Level-1 X.25 |
+------------------------------+
 
C.1. X.25 Addressing Restrictions
 
When an X.25 call is made over a PSDN, the Network User Address (NUA)
of the destination must be specified in order that the PTT may route
the call. The call placed is directed to the termination equipment
upon the user's premises.
 
It is possible to provide extra information in the Call Request
Packet in addition to the mandatory NUA required by the PTT.
 
This extra information may be of 2 kinds:
 
(a) A subaddress:
 
It is simply an extension to the address and it is put into the
called address field of the Call Request Packet. This
information (Address + Subaddress) is taken from the destination
address field of the F_CONNECT_RQ; therefore, from the user's
point of view, there is no distinction between the main address
and subaddress parts.

<a href="http://ietfdocs.potaroo.net/idref/rfc5024">RFC 5024</a> ODETTE FTP 2 November 2007
 
 
(b) User data:
 
There is no standard for user data. Moreover, there is no
information in the F_CONNECT_RQ from which the ODETTE-entity may
derive user data to be put in the N_CONNECT_RQ; therefore, user
data shall not be used.
 
C.2. Special Logic
 
The SSID field SSIDSPEC specifies whether special logic must be
applied (Y (yes) or N (no)) to the Data Exchange Buffer before the
ODETTE-FTP moves the data into the NSDU (Network Service Data Unit)
and passes control to the Network Service.
 
C.2.1. When Special Logic Is Not To Be Used
 
This logic is not applied to SSRM and SSID commands.
 
C.2.2. The Need for "Enveloping" Exchange Buffers
 
The "special-logic" parameter was created in order to allow the use
of ODETTE-FTP over asynchronous links. The "special-logic" could be
needed to enable terminals to access an X.25 network via an
asynchronous entry (through a PAD: Packet Assembly / Disassembly).
The "special-logic" is not needed in case of a whole X.25 connection.
This "special-logic" realises a CRC function in order to detect
errors due to the asynchronous medium.
 
Negotiation of the "special-logic" parameter in the SSID command is
as follows:
 
SSID SSID
-----------------------------------------------
 
special-logic=yes ---------------------&gt;
 
&lt;------------------------------------ special-logic=yes
or
&lt;------------------------------------ special-logic=no
 
special-logic=no ----------------------&gt;
 
&lt;------------------------------------ special-logic=no
 
This logic is activated when the "special-logic" parameter in the
SSID specifies Y (yes).

<a name="page-106"> </a>
<a href="http://ietfdocs.potaroo.net/idref/rfc5024">RFC 5024</a> ODETTE FTP 2 November 2007
 
 
Special logic processing, when activated, will function within level
4 of the OSI model.

+------------------------------+
 
C.2.3. Responsibilities of Special Logic
 
When transmitting an Exchange Buffer and special logic is active,
layer 4 will wrap the Exchange Buffer in synchronization and
delineation characters, then protect the data integrity by means of a
block checksum (BCS). When receiving an Exchange Buffer and special
logic is active, layer 4 will remove such things as synchronization
and delineation characters, etc., before passing the Exchange Buffer
to the higher layers.
 
C.2.4. Extended Exchange Buffer Format
 
Each envelope has a 1-byte header prefixed to it, and a 2-byte
checksum appended to the end. The checksum is derived in a manner
specified in the ISO DIS 8073 TRANSPORT LAYER documentation.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Friend Informational [Page 106]
<a name="page-107"> </a>
<a href="http://ietfdocs.potaroo.net/idref/rfc5024">RFC 5024</a> ODETTE FTP 2 November 2007
 
 
The layout of the data buffer will be structured as follows:
 
+------------------------------------------------------------------+
| S | B | | B | C |
| T | S | COMPLETE EXCHANGE BUFFER (CEB) | C | / |
| X | N | | S | R |
+------------------------------------------------------------------+
A A A A
| | | |
| +------------- Block sequence number | |
| | |
+----------------- Synchronization character | |
| |
Block checksum -----------------------+ |
|
Delineation character --------------------+
 
The envelope is initialised with an STX and the checksum variables
are set to 0. The leading STX is not protected by the checksum
calculation but is explicitly protected by a character compare at the
receiver's end. The Exchange Buffer is processed character by
character. As each character is removed from the Exchange Buffer, it
is put through the checksum calculation and then, prior to its
insertion in the envelope, it is put through the Shift-out
transparency logic, which will result in either one or two characters
being inserted. When the contents of the Exchange Buffer have been
entirely processed, then the checksum variables are brought up to
date by inserting two X'00's through the checksum calculator and the
two resultant checksum characters forwarded to the Shift-out
transparency logic for insertion into the envelope. Finally, a
carriage return (CR) is appended to the envelope. The segment is now
ready for transmission to line.
 
Upon receipt of a valid envelope that has the correct sequence
number, the host should increment his sequence number register ready
for the next transmission.
 
The receiver will initialise his receiving buffer area upon receipt
of an STX character, place the STX at the beginning of the buffer,
and reset checksum variables. All subsequent characters are
processed using Shift-out logic before they are inserted into the
buffer, at which point they will NOT be processed by the checksum
calculator, although the character following the Shift-out (after
subtracting X'20') will be. The checksum characters themselves will
be processed by the checksum calculator by virtue of the design of
the checksum algorithm.

C.2.5. Error recovery
 
C.2.5.1. Mechanism
 
The error correction scheme is implemented by the definition of three
timers and the use of an ASCII NAK (Negative Acknowledgement)
character followed by a C/R. The &lt;NAK&gt;&lt;C/R&gt; will flow between the
two session partners, but only as a consequence of previous bad data.
 
A user of the error recovery correcting extension must always work
with a credit value of 1. This can be forced upon any session
partner at SSID negotiation. The effect will be to force a simple
half-duplex flip-flop protocol.
 
Upon receipt of a bad block, send &lt;NAK&gt;&lt;C/R&gt; to the session partner.
 
Upon receipt of a &lt;NAK&gt;&lt;C/R&gt;, a session partner should retransmit the
last block in its entirety.
 
C.2.5.2. Timers
 
The majority of error conditions will be detected by a bad BCS
sequence. However, certain conditions cannot be so detected. For
example, a corrupt C/R will mean that the receiver will not know that
the end of a block has been reached. No matter how long he waits, no
more data will come from the sender. Thus, a timer is the only way
to detect this type of corruption. There are three timers needed to
detect all possible malignant conditions of this type.
 
T1 - Exchange Buffer Time Out (Inactivity or Response)
T2 - Inter Character Time Out
T3 - Data Carrier Detect Loss Time Out
 
The three timers are in addition to the timer defined in the original
protocol.
 
TIMER T1 - RESPONSE TIME OUT (DEFAULT = 45 SECONDS):
 
Used to detect a high-level block Time Out, e.g., the Time Out
between an SFID and its associated SFPA or SFNA response.
 
Started - It is started after the last character of an exchange
buffer has been sent to the line.
 
Stopped - It is stopped when an STX has been received.
 
Expiry - Retransmit the whole block again, until such time as the
retry limit has been reached.

<a name="page-109"> </a>
<a href="http://ietfdocs.potaroo.net/idref/rfc5024">RFC 5024</a> ODETTE FTP 2 November 2007
 
 
TIMER T2 - INTER CHARACTER TIME OUT (DEFAULT = 7 SECONDS):
 
Used to detect errors in the reception of individual characters.
 
Started - For an asynchronous entity, it is started upon receipt
of each character while in synchronisation mode. For an
X.25 entity, it is started after a received block that
did not terminate an Exchange Buffer.
 
Stopped - Upon receipt of the next character.
 
Expiry - Send a &lt;NAK&gt;&lt;C/R&gt;, drop out of synchronised mode, and go
back and listen to line.
 
TIMER T3 - DATA CARRIER TEMPORARY LOSS (DEFAULT = 1 SECOND):
 
Used by an asynchronous entity only and is used to detect a
temporary carrier failure.
 
Started - When DCD (Data Carrier Detect) is lost.
 
Stopped - When DCD is regained.
 
Expiry - Disconnect the session.
 
C.2.5.3. Types of Error
 
Data corruption when it occurs can be categorised in one of five
ways:
 
(1) CORRUPT STX (START OF TEXT)
 
In this situation the STX is not seen and synchronisation is not
achieved. The terminating C/R is received out of synchronisation
and hence the block is not seen by the receiver. A &lt;NAK&gt;&lt;C/R&gt; is
transmitted to the sender to indicate this. The sender should then
retransmit the last block (each implementation will need to set a
retry limit to be used for the number of consecutive times it
attempts to retransmit a block -- a default limit of 5 is
recommended). All data received outside synchronisation (except
&lt;NAK&gt;&lt;C/R&gt;) are ignored.

(3) BAD DATA
(4) BAD BCS (BLOCK CHECK SUM)
 
In this situation, the receiver is unable to tell whether the error
is bad data or bad BCS. In either case, the response is to discard
the Exchange Buffer and send a &lt;NAK&gt;&lt;C/R&gt;.

(5) BAD BLOCK SEQUENCE NUMBER (BSN)
 
A circular sequential number (0 up to and including 9) is assigned
to transmitted Exchange Buffers. This is to aid detection of
duplicate or out-of-sequence Exchange Buffers. Once a duplicate
block is detected, the Exchange Buffer in question is discarded.
Once an out of sequence block is detected, this should result in a
protocol violation.

<a name="section-3">3</a>. Shift-out transparency (See TRANSMIT/RECEIVE logic.)
 
To avoid appearance of any control characters in the data stream,
all the characters of the extended Exchange Buffer (with exception
of the STX and carriage return characters enveloping the buffer)
are put through a Shift-out logic, which result in a character
being inserted (SO) and adding hex value '20' to the control
character.
 
<a name="section-4">4</a>. The carriage return is inserted at the end of the data buffer.
 
Note: After adding STX, BSN, BCS, CR, and SO-logic, the data buffer
may exceed the Data Exchange Buffer size.
 
C.2.7. Checksum Creation Algorithm
 
These follow the ISO DIS 8073 TRANSPORT LAYER standard.
 
SYMBOLS:
 
The following symbols are used:
 
C0,C1 Variables used in the algorithm
L Length of the complete NSDU
X Value of the first octet of the checksum parameter
Y Value of the second octet of the checksum parameter
 
ARITHMETIC CONVENTIONS:
 
Addition is performed in one of the two following modes:
 
a) modulo 255 arithmetic
b) one's complement arithmetic in which if any of the variables
has the value minus zero (i.e., 255) it shall be regarded as
though if was plus zero (i.e., 0).
 
ALGORITHM FOR GENERATING CHECKSUM PARAMETERS:
 
. Set up the complete NSDU with the value of the checksum parameter
field set to zero.
 
. Initialise C0 and C1 to zero.
 
. Process each octet sequentially from i=1 to L by
 
a) adding the value of the octet to C0, then
b) adding the value of C0 to C1.

. Calculate X and Y such that
 
X = C0 - C1
Y = C1 - 2*C0
 
. Place the values X and Y in the checksum bytes 1 and 2,
respectively.
 
C.2.8. Algorithm for checking checksum parameters
 
. Initialise parameters C0 and C1 to zero.
 
. Process each octet of NSDU sequentially from i=1 to L by
 
a) adding the value of the octet to C0, then
b) adding the value of C0 to C1.
 
. If, when all the octets have been processed, either or both C0
and C1 does not have the value zero, then the checksum formulas
have not been satisfied.
 
Note that the nature of the algorithm is such that it is not
necessary to compare explicitly the stored checksum bytes.

C.3. PAD Parameter Profile
 
Before an (ODETTE-FTP) asynchronous entity --&gt; Modem --&gt; PAD --&gt;
(ODETTE-FTP) native X.25 link can be established, the target PAD
parameters must be set such that correct communication is
established. It is strongly recommended that the PAD parameters are
set by the X.25 entity. CCITT recommendations X.3, X.28, and X.29
define the PAD parameters and procedures for exchange of control
information and user data between a PAD and a packet mode Data
Terminal Equipment (DTE).
 
Following is the Parameter list and values used to set the PAD for
ODETTE-FTP communication. For further detailed information see the
specification for CCITT X.25, X.28, X.29 and X.3.

- Parameters 1 - 12 are mandatory and available internationally.
- Parameters 13 - 22 may be available on certain networks and may
also be available internationally.
- A parameter value may be mandatory or optional.
 
The ODETTE profile refers only to parameter values which must be
internationally implemented if the parameter is made available
internationally.
 
The ODETTE-FTP "special-logic" parameter may be impossible on some
PADs because they do not support of some of the parameters (13 - 22).
(If the PAD is supporting parity check (21) by default, ODETTE-FTP
special logic would be impossible.)
 
It is a user responsibility to ensure special logic consistency when
making the PAD subscription.
 
Note 2:
 
Some parameters may have to be set differently depending on:
- Make and function of the start-stop mode DTE entity.
- Start-stop mode DTE entity ODETTE-FTP monitor function.
- PAD services implemented.
- Packet mode DTE entity ODETTE-FTP monitor function.

Appendix D. OFTP X.25 over ISDN Recommendation
 
This appendix describes the recommendation of ODETTE Group 4 (1) for
the use of OFTP (2) over X.25 over ISDN.
 
(1) ODETTE Group 4 is responsible for the specification of
Telecommunications standards and recommendations for use
within the Automotive Industry.
 
(2) OFTP (ODETTE File Transfer Protocol) is the communications
standard specified by ODETTE Group 4 designed for the transfer
of both EDI and non-EDI data.
 
This document offers an introductory overview of a technical subject.
It is structured to contain the ODETTE recommendation, together with
introductory information for the person not familiar with ISDN, and
notes on the issues associated with the implementation of the
recommendation.
 
The first section provides the detailed ODETTE recommendation, which
is followed by a general discussion. If you are not familiar with
the terminology, please read the subsequent sections first.
 
How far an existing X.25 Line adapter may be replaced by an ISDN line
adapter in an installation depends on the opportunities in view of
connections (X.25 or ISDN) of the involved partners for file
transfer.
 
Companies that keep many connections to external partners (for
example, car manufacturing companies) may use the OFTP file transfer
in view of compatibility, which must always be considered anyway only
in parallel to the X.25 network.
 
It is not the aim of this recommendation to remove the OFTP file
transfer generally from the X.25 network to the ISDN network. This
will not always be possible for international connections because of
technical reasons, and this does not always make sense for
connections with a low size of data to be transmitted.
 
Certainly, the use of ISDN, when exchanging a high volume of data
(for example, CAD/CAM files), is very much cheaper than the use of an
X.25 network. For such cases, this recommendation shall provide a
cost-effective possibility for file transfer.
 
This appendix is organized as follows. D.1 defines the ODETTE
recommendation in these terms, D.2 introduces the ISDN environment to
the unfamiliar reader, D.3 describes the various methods of
connecting to ISDN, and D.4 covers implementation issues.

include a timeout control.
 
An ISDN connection (B channel) should be released
if no X.25 packets have been transmitted on this
connection for a longer time. For flexibility a
variable user definable timer should be
incorporated into the adapter.

In the event of a timeout situation the adapter

D.2. Introduction to ISDN
 
The use of digital encoding techniques over such high-quality,
error-free backbone networks has allowed the PTTs to offer high
bandwidths to the end user. The service is named ISDN (Integrated
Services Digital Network).
 
The increasing need to transfer larger volumes of EDI data, in
particular CAD/CAM drawings, has focused attention upon high-speed,
low-cost communication. The traditional X.25 over a Packet Switched
Data Network (PSDN) has been a good general purpose communications
subsystem. Unfortunately, its cost and transfer speed make PSDN
expensive for the new requirement.
 
X.25 over the new ISDN provides both the transfer speed and cost
benefits to satisfy the new requirements.
 
We include the following terminology because for us to make sense of
ISDN and X.25, it is important that we use definitions precisely and
avoid the abuses of the past.
 
ISDN: Integrated Services Digital Network
 
X.25: X.25 is a communications protocol. It defines the
structure of data packets that comprise the protocol and
the manner in which they are used.
 
PSDN: A PSDN (Packet Switched Data Network) is a network over
which the X.25 protocol is operated.
 
PSPDN: A PSPDN (Packet Switched Public Data Network) is a PSDN
operated by the PTTs. PSPDNs are given trade names,
such as PSS in the UK, Datex-P in Germany, and Transpac
in France.
 
BRI: Basic Rate Interface, also known as Basic Rate Access,
defines an ISDN facility with 2 x 64 K B channels.
 
PRI: Primary Rate Interface, also known as Primary Rate
Access, defines an ISDN facility with 30 x 64 K B
channels.

Channels: ISDN is typically brought into a consumer's premises
using a twisted pair of wire. Over this wire, data can
be transmitted in frequency bands. These frequency
bands are allocated as channels.
 
B channels: The B channels are the data channels and operate at 64
Kb. The two end users of a connection will communicate
over a B channel.
 
D channel: Signalling on ISDN is performed over the D channel.
Signalling is used to set up and release connections on
the B channels. In some countries, the D channel can
also be used for limited X.25 access to the PTTs' PSDN.
 
The D channel operates at the lower speed of 16 Kb as it
is normally used only at the beginning and end of a
connection.
 
Bandwidth Allocation:
2 Wire B2 - 64 Kb
Twisted Pair B1 - 64 Kb
D Channel - 16 Kb
 
The standard for the operation of the D channel is
called ETSI and is used in most European countries.
However, some countries that started the introduction
very early used proprietary standards, for example:
 
1TR6 - Used in Germany
BTNR - Used in the UK
 
Although there are D channel variations, this will not
affect communications over the B channels as the
communication over the D channel is between the
subscriber and the ISDN service provider.
 
However, the consumer's equipment must be able to handle
the channel D signalling operated by the ISDN service
provider and so there may be a problem of equipment
availability and certification.
 
All the PTTs have committed to migrate to ETSI (also
known as EURO-ISDN and Q.931) and many are currently
supporting both their national variant and ETSI. It is
advisable that in this situation the subscriber select
the ETSI variant to avoid unnecessary equipment
obsolescence.

Services: The high-speed service is provided in two forms, Basic
and Primary.
 
Basic: 2+D, the D 2B channel operates at 16 Kb. The
Basic Rate access is normally provided to the subscriber
over simple twisted pair cable.
 
Primary: 30B+D, the D channel operates at 64 Kb.
Primary Rate access is normally provided to the
subscriber over shielded coaxial cable. Note that the
bandwidth for Primary is 2.048 Mbit/s.
 
Protocols: The B channel is a binary channel and is transparent to
the flow of data. Therefore, all of the currently
available protocols can operate over a B channel. The
most common protocol is X.25.
 
X.25: The X.25 protocol is a primary protocol for open
computer-to-computer communication.
 
Passive Bus: It is possible to have an ISDN service enter a building
and then have an 8-core cable laid within the building
with multiple ISDN junction points, in the same way as
one would have multiple telephone points (extensions)
for a particular external telephone line.
 
Connection Setup
 
The adapter is responsible for analysing the outgoing X.25 call
request and making an ISDN call to a derived ISDN address,
establishing a new X.25 level-2 and level-3, and then propagating
the X.25 Call Request Packet.
 
Connection Termination
 
The termination phase of the X.25 call is made with a Clear
Request and finalised with a Clear Confirmation. The recipient of
the Clear Confirm should then close down the ISDN connection.
 
The clear down of the ISDN connection should only be made if there
are no other Switched Virtual Circuits (SVCs) active on the ISDN
connection; note that the usage of multiple simultaneous SVCs is
only by virtue of bilateral agreement.

D.3. Equipment Types
 
There are a number of ways in which ISDN/X.25 access can be made.
 
Integrated Adapter
 
This is normally a PC-based ISDN adapter inside a PC. It is
normal in such an environment that the OFTP application has the
ability to manipulate the ISDN and X.25 aspects of the session
independently and therefore have complete control.
 
Equally important is that the speed of communication between the
adapter and the application are at PC BUS speeds. It is
therefore more likely that the effective transmission speed will
be nearer the 64K limit.
 
The other benefit of such a direct linkage is that both 64K B
channels may be used in parallel and both able to operate at
64Kb.
 
Elementary Terminal Adapter
 
In this scenario, the computer has an integral X.25 adapter
communicating X.21 with a Terminal Adapter that fronts the ISDN
network. This allows a host with a X.25 capability to interface
to ISDN, normally on a one-to-one basis.
 
The interface between the Terminal Adapter and the PC will
typically only support one 64K B channel. This is obviously an
inefficient usage of the ISDN service.
 
Because the linkage between the computer and the Terminal Adapter
is only X.25, then some modification/configuration may be needed
inside the Terminal Adapter when new users are added.
 
X.25 Switch
 
This solution is normally found inside the larger corporates
where an internal X.25 network is operated or where dual X.25 and
ISDN is required.
 
The main benefit of a switch is to support both PSDN and ISDN
simultaneously. Also, multiple X.21 lines may be implemented
between the X.25 switch and the computer.
 
This solution normally requires more effort to configure and may
require obligations to be placed upon how incoming callers
specify routing.

D.4. Implementation
 
The adoption of ISDN as an additional subsystem to support OFTP
communications has associated implementation problems, which can be
categorised as below:
 
X.25/ISDN Addressing
Making a Call
Receiving a Call
Logical Channel Assignment
Facilities Negotiation
ISDN Call Attributes
Homologation Issues
Growth
Performance
 
D.4.1. X.25/ISDN Addressing
 
The original OFTP was designed to work over the X.25 networks
provided by the PTTs (PSPDNs). The national X.25 networks were
interconnected to provide a global X.25 network, and a common
addressing scheme was adopted by all. Although there were a few
differences in addressing within a national network, the interface to
other countries was quite rigid and normalised.
 
PSPDN Numbering
 
The addressing scheme adopted in X.25 is a 15-digit number
(Network User Address, NUA) where the first three identify the
country, the fourth digit identifies the network within the
country, and the remainder specify the individual subscriber plus
an optional subaddress. In the UK where a full X.25 numbering
scheme is adopted, a NUA is, e.g., 234221200170, where 2342 is the
DNIC (Data Network Identification Code) and 21200170 is the
subscriber number.
 
ISDN Numbering
 
ISDN is an extension of the normal telephone system; consequently,
it adopts (or rather is) the same numbering scheme as the
telephone system (PSTN).
 
The Numbering Conflict
 
The PSDN and PSTN numbering schemes are two totally different
numbering schemes. There is no relationship between them. It is
this conflict that is at the heart of the matter.

<a href="http://ietfdocs.potaroo.net/idref/rfc5024">RFC 5024</a> ODETTE FTP 2 November 2007
 
 
D.4.2. Making a Call
 
It is a consequence of PSDN and PSTN being based upon different and
unconnected numbering schemes that the key problem arises.
 
For X.25 to work over ISDN, three main methods of addressing are
available:
 
Un-mapped: The X.25 called NUA is used as the PSTN number. Thus,
an X.25 call to 0733394023 will result in a PSTN call
to 0733394023 and the call request that consequently
flows will also be to 0733394023.
 
Manipulated: The X.25 called NUA is manipulated by the subtraction
and/or addition of digits to derive a resultant PSTN
number. Thus, 2394023 could be manipulated to derive
a PSTN number of 00944733394023, where the prefix 2 is
deleted and replaced by 00944733.
 
Mapped: The X.25 called NUA is used as a look-up into a table
of PSTN numbers. Thus, an X.25 call to 234221200170
could be mapped to and result in a PSTN call to
0733394023 and the call request that consequently
flows will remain as 234221200170.
 
Un-mapped Calls
 
Un-mapped calls are where the host-specified X.25 NUA is converted
directly to the corresponding ISDN number.
 
Thus, an X.25 call issued by the host to X.25 NUA 0733394023 will
result in an ISDN call to the PSTN number 0733394023. After the
call has been established, then HDLC/X.25 protocol setup will be
established after which an X.25 call request will be transferred
with the NUA 0733394023.
 
When a PSTN call is made, the number of digits in the called
number vary depending upon the location of the called party.
 
When a number is called, it may be local, national, or
international.
 
local: 394023
national: 0733 394023
international: 009 44 733 394023
 
Depending upon where a call originates, the corresponding X.25 NUA
in the call request packet will vary dramatically.
 
 
 
Friend Informational [Page 125]
<a name="page-126"> </a>
<a href="http://ietfdocs.potaroo.net/idref/rfc5024">RFC 5024</a> ODETTE FTP 2 November 2007
 
 
Such variation of X.25 NUA, in particular the changing prefix, can
be difficult to be accommodated by X.25 routing logic in many
products.
 
When an international PSTN call is being made, then it is likely
that the PSTN number exceeds 15 digits, which is the maximum
length of an X.25 NUA. Therefore, using un-mapped addressing may
make some international calls impossible to make.
 
Manipulated Calls
 
The X.25 called NUA is manipulated by the subtraction and/or
addition of digits to derive a resultant PSTN number.
 
Let us assume that by internal convention we have identified the
prefix '2' to indicate an international ISDN call. Thus, an X.25
call request of 244733394023 could be manipulated to derive a PSTN
number of 00944733394023, where the prefix '2' is deleted and
replaced by '009' (the international prefix).
 
The X.25 called NUA would typically be left in its un-manipulated
state. As individual internal conventions vary, the X.25 called
NUA will vary. In the case above, it would be 244733394023, but
another installation might have the convention where a prefix of
'56' specifies the UK and so the NUA will be 56733394023, where
the '56' is deleted and replaced with '00944' to derive the PSTN
number.
 
Mapped Calls
 
The mapped method offers maximum flexibility in that:
 
The PSTN number can exceed 15 digits.
 
The X.25 NUA and PSTN number can be totally different.
 
The problem with mapped calls is administrative. IBM mainframes
can't handle X.25 over ISDN at all, let alone support mapping.
For the mainframe solution to work, an external X.25/ISDN router
box is required and it is the responsibility of the external box
to provide any mapping necessary.
 
This means that any changes or addition of OFTP partners over ISDN
will require access to the computer room or special configuration
equipment to change the tables inside the external X.25/ISDN
router box.

D.4.3. Receiving a Call
 
We have seen from the previous section that the called X.25 NUA
from an ISDN incoming call may vary considerably. If ISDN/X.25 is
confined to a national boundary, then such variation will not be
so great as most calls will have matching called X.25 NUA and PSTN
numbers.
 
X.25 switches and X.25 adapters normally route/accept/reject calls
based upon their X.25 called NUA. In particular, routing is made
upon the X.25 called NUA subaddress.
 
To derive this subaddress, there are 2 methods:
 
1) the last 'n' digits are analysed.
 
2) the base X.25 NUA of the line is removed from the called NUA.
For example, if the called X.25 NUA is 23422120017010 and the
PSDN subscriber NUA is 234221200170, then the subaddress
derived from subtraction is 10.
 
Obviously, the second method will not work if the incoming NUA
varies.
 
ISDN Features
 
ISDN, like X.25, has a core set of features that are then enriched
with options. In the original OFTP X.25 specification, it was
decided that the Q-bit and D-bit options were not common to all
networks or applications; they were therefore positively excluded
from the specification.
 
It is proposed that apart from the core ISDN features necessary to
establish a call, no other features be used.
 
Subaddressing
 
There are two forms of ISDN subaddressing, overdialled and specific.
 
The overdial method allows an ISDN number to be artificially
extended. A typical case would be where a private exchange has been
installed in a larger company. Assume that the base number is
394023 and the computer is on internal extension 1234, then by
specifying an ISDN number of 3940231234, direct access may be made
to the internal extension.

<a name="page-128"> </a>
<a href="http://ietfdocs.potaroo.net/idref/rfc5024">RFC 5024</a> ODETTE FTP 2 November 2007
 
 
The problem with this method is that it extends to called number and
may, especially for international access, exceed the ISDN numbering
limits between countries.
 
The other method of subaddressing is where a discrete subaddress is
placed in a specific field in the ISDN call setup.
 
The problem with this method, is that it requires the caller to
place the subaddress in the ISDN call setup. Not all ISDN
implementations will allow this insertion.
 
In conclusion, subaddressing of any kind should be avoided.
 
D.4.4. Logical Channel Assignment
 
An X.25 dataline will have associated with it a number of logical
channels.
 
The number of channels is a part of the agreement between the PTT
and the subscriber. The number of channels subscribed to is
important; call failure and similar problems will result if the
number of logical channels defined at the two remote ends are
different.
 
If a DTE makes a call out, then the highest defined logical channel
number will be selected. If the remote Data Communications
Equipment (DCE) does not have the same number of logical channels
defined, then an invalid logical channel is being used from the
perspective of the recipient DCE and the call will be rejected.
 
D.4.5. Facilities Negotiation
 
In the PSPDN environment, it is possible to subscribe to negotiation
of window size and packet size. Although this negotiation requested
by the originator's DTE may be propagated to the remote DTE at the
discretion of the originator's DCE, it is a local responsibility
between the DTE and DCE pair.
 
In the ISDN scenario where it is a DTE-DTE type connection, the
window size and packet size may be left at the default value and
consequently the values may be omitted from the call request. If no
values are specified, then it is vital that both DTEs have
configured themselves to the recommended defaults.
 
The symptom of a window size mismatch is a hang situation without
any informational error codes.

The symptoms of a packet size mismatch could work in some scenarios,
but would otherwise issue error codes indicating invalid packet
sizes.
 
Window Size
 
The CCITT X.25 window size has a default value of '2', although
subscribers may have other default window sizes, e.g., '7', by
virtue of agreement with the PTT.
 
Window size negotiation can be explicitly requested by specifying
the requested window size in the Facilities fields in the Call
Request packet.
 
Packet Size
 
The CCITT X.25 packet size has a default value of '128' octets,
although subscribers may have other default values, e.g., '1024',
agreed with the PTT.
 
D.4.6. ISDN Call Setup
 
The initial setup of an ISDN call is initiated with the
transmission of a Q.931 SETUP command. Apart from requesting that
a call be established, the SETUP command can optionally carry
information about the calling party, the called party, routing
information, the type of circuit required (e.g., voice or data),
and information about the protocols that are requested to be
established.
 
Setup Parameters:
 
Bearer capability Information transfer and
access attributes
 
Called Party number Destination's network address
 
Called Party subaddress Destination's complete
address
 
Calling Party number Source's network address
 
Low-layer compatibility Layer 1-3 indication
 
High-layer compatibility Layer 4-7 indication

D.4.7. Homologation Issues
 
Homologation procedures were adopted and vigorously enforced by the
PTTs with respect to the quality and conformance of communications
equipment connected to the services provided by the PTTs.
 
In particular, commercial X.25 products had to be tested and approved
before they could be connected to the PTTs' PSPDN. The advantage of
this to the subscriber was that there was very little chance of the
approved equipment not working.
 
With ISDN, similar approval standards are still enforced. So the
subscriber has the same confidence in their ISDN equipment. Wrong,
the ISDN equipment itself is approved, but the X.15 protocol that
operates on top of ISDN is now outside of the scope of approval
services.
 
This means that quality of conformance to standards of X.25 over ISDN
is subject to the variable quality procedures within the various ISDN
equipment manufacturers.
 
Although it is likely that commercial reputation will place pressure
upon the manufacturers with a programming bug to correct such errors,
it still requires the subscribers that do not communicate well to put
time and effort into finding the party with the error.
 
So far, tests have shown a number of subtle errors, such as timing
problems, that have taken many days to find, prove, and fix.
 
D.4.8. Growth
 
Primary Rate Access
 
If a user decides to plan for growth from the beginning, then the
Primary Rate Access has apparent financial benefits. Such
apparent savings are usually lost due to the increased cost of
user hardware to support such an interface. The BRI for data
usage is very common and cards/adapters are low in cost, whereas
the PRI cards/adapters are few and far between and consequently
highly priced.
 
Basic Rate Access
 
One way to grow with ISDN is to buy multiple BRI lines, increasing
slowly in units of 2 x B channels. The PTTs will be able to
provide the same subscriber number for all the lines provided in a
similar way to the traditional hunting group associated with PSTN
type working.

D.4.9. Performance
 
The obvious benefit of ISDN is speed; unfortunately, the majority
of computer systems in use today have a finite amount of computing
power available. The attachment of multiple active high-speed
communication lines used in file transfer mode could take a
significant amount of CPU resource to the detriment of other users
on the system.
 
Connecting an ISDN line with the default 2 B channels to your
computer using an X.21 interface is going to give a consistent 64
Kb throughput only if one of the B channels is active at any one
time.
 
If there are two 64 Kb channels active and contending for a single
64 Kb X.21 interface, then effective throughput will be reduced
significantly to just over 50%.
 
Mainframe issues:
 
Users with a mainframe front-end are also going to find cost an
issue. The scanners that scan the communications interfaces are
based upon aggregate throughput. A 64 Kb interface takes up a lot
of cycles.
 
Determining 'DTE' or 'DCE' Characteristics
 
The following section is an extract from the ISO/IEC 8208
(International Standards Organization, International
Electrotechnical Commission) (1990-03-15) standard, which is an
ISO extension of the CCITT X.25 standard.
 
The restart procedure can be used to determine whether the DTE
acts as a DCE or maintains its role as a DTE with respect to the
logical channel selection during Virtual Call establishment and
resolution of Virtual Call collision.
 
When prepared to initialise the Packet Layer, the DTE shall
initiate the restart procedure (i.e., transmit a RESTART REQUEST
packet). The determination is based on the response received from
the data exchange equipment (DXE) as outlined below.
 
a) If the DTE receives a RESTART INDICATION packet with a
restarting cause code that is not 'DTE Originated' (i.e., it
came from a DCE), then the DTE shall maintain its role as a DTE.

<a href="http://ietfdocs.potaroo.net/idref/rfc5024">RFC 5024</a> ODETTE FTP 2 November 2007
 
 
b) If the DTE receives a RESTART INDICATION packet with a
restarting cause code of 'DTE Originated' (i.e., it came from
another DTE), then the DTE shall confirm the restart and act as
a DCE.
 
c) If the DTE receives a RESTART INDICATION packet with a
restarting cause code of 'DTE Originated' (i.e., it came from
another DTE) and it does not have an unconfirmed RESTART REQUEST
packet outstanding (i.e., a restart collision), then the DTE
shall consider this restart procedure completed but shall take
no further action except to transmit another RESTART REQUEST
packet after some randomly chosen time delay.
 
d) If the DTE issues a RESTART REQUEST packet that is subsequently
confirmed with a RESTART CONFIRMATION packet, then the DTE shall
maintain its role as a DTE.

GNU AFFERO GENERAL PUBLIC LICENSE
Version 3, 19 November 2007
 
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
 
Preamble
 
The GNU Affero General Public License is a free, copyleft license for
software and other kinds of works, specifically designed to ensure
cooperation with the community in the case of network server software.
 
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
our General Public Licenses are intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users.
 
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
 
Developers that use our General Public Licenses protect your rights
with two steps: (1) assert copyright on the software, and (2) offer
you this License which gives you legal permission to copy, distribute
and/or modify the software.
 
A secondary benefit of defending all users' freedom is that
improvements made in alternate versions of the program, if they
receive widespread use, become available for other developers to
incorporate. Many developers of free software are heartened and
encouraged by the resulting cooperation. However, in the case of
software used on network servers, this result may fail to come about.
The GNU General Public License permits making a modified version and
letting the public access it on a server without ever releasing its
source code to the public.
 
The GNU Affero General Public License is designed specifically to
ensure that, in such cases, the modified source code becomes available
to the community. It requires the operator of a network server to
provide the source code of the modified version running there to the
users of that server. Therefore, public use of a modified version, on
a publicly accessible server, gives the public access to the source
code of the modified version.
 
An older license, called the Affero General Public License and
published by Affero, was designed to accomplish similar goals. This is
a different license, not a version of the Affero GPL, but Affero has
released a new version of the Affero GPL which permits relicensing under
this license.
 
The precise terms and conditions for copying, distribution and
modification follow.
 
TERMS AND CONDITIONS
 
0. Definitions.
 
"This License" refers to version 3 of the GNU Affero General Public License.
 
"Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
 
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
 
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.
 
A "covered work" means either the unmodified Program or a work based
on the Program.
 
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
 
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
 
An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
 
1. Source Code.
 
The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.
 
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
 
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
 
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
 
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
 
The Corresponding Source for a work in source code form is that
same work.
 
2. Basic Permissions.
 
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
 
You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
 
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
 
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
 
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
 
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
 
4. Conveying Verbatim Copies.
 
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
 
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
 
5. Conveying Modified Source Versions.
 
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
 
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
 
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
 
c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
 
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
 
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
 
6. Conveying Non-Source Forms.
 
You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
 
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
 
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
 
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
 
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
 
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
 
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
 
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
 
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
 
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
 
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
 
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
 
7. Additional Terms.
 
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
 
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
 
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
 
a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
 
b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
 
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
 
d) Limiting the use for publicity purposes of names of licensors or
authors of the material; or
 
e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
 
f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions of
it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on
those licensors and authors.
 
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
 
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
 
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
 
8. Termination.
 
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
 
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
 
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
 
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
 
9. Acceptance Not Required for Having Copies.
 
You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
 
10. Automatic Licensing of Downstream Recipients.
 
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
 
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
 
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
 
11. Patents.
 
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
 
A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
 
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
 
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
 
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
 
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
 
A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
 
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
 
12. No Surrender of Others' Freedom.
 
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
 
13. Remote Network Interaction; Use with the GNU General Public License.
 
Notwithstanding any other provision of this License, if you modify the
Program, your modified version must prominently offer all users
interacting with it remotely through a computer network (if your version
supports such interaction) an opportunity to receive the Corresponding
Source of your version by providing access to the Corresponding Source
from a network server at no charge, through some standard or customary
means of facilitating copying of software. This Corresponding Source
shall include the Corresponding Source for any work covered by version 3
of the GNU General Public License that is incorporated pursuant to the
following paragraph.
 
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the work with which it is combined will remain governed by version
3 of the GNU General Public License.
 
14. Revised Versions of this License.
 
The Free Software Foundation may publish revised and/or new versions of
the GNU Affero General Public License from time to time. Such new versions
will be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
 
Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the GNU Affero General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU Affero General Public License, you may choose any version ever published
by the Free Software Foundation.
 
If the Program specifies that a proxy can decide which future
versions of the GNU Affero General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
 
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
 
15. Disclaimer of Warranty.
 
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
 
16. Limitation of Liability.
 
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
 
17. Interpretation of Sections 15 and 16.
 
If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.
 
END OF TERMS AND CONDITIONS
 
How to Apply These Terms to Your New Programs
 
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
 
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
 
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
 
This program is free software: you can redistribute it and/or modify
it under the terms of the GNU Affero General Public License as published by
the Free Software Foundation, either version 3 of the License, or
(at your option) any later version.
 
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU Affero General Public License for more details.
 
You should have received a copy of the GNU Affero General Public License
along with this program. If not, see <http://www.gnu.org/licenses/>.
 
Also add information on how to contact you by electronic and paper mail.
 
If your software can interact with users remotely through a computer
network, you should also make sure that it provides a way for users to
get its source. For example, if your program is a web application, its
interface could display a "Source" link that leads users to an archive
of the code. There are many ways you could offer source, and different
solutions will be better for different programs; see section 13 for the
specific requirements.
 
You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU AGPL, see
<http://www.gnu.org/licenses/>.

3. Grant of Patent License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
 
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
 
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
 
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and
 
(c) You must retain, in the Source form of any Derivative Works

distribution, then any Derivative Works that You distribute must
include a readable copy of the attribution notices contained
within such NOTICE file, excluding those notices that do not
pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
 
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
 
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
 
6. Trademarks. This License does not grant permission to use the trade
names, trademarks, service marks, or product names of the Licensor,
except as required for reasonable and customary use in describing the
origin of the Work and reproducing the content of the NOTICE file.
 
7. Disclaimer of Warranty. Unless required by applicable law or
agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

risks associated with Your exercise of permissions under this License.
 
8. Limitation of Liability. In no event and under no legal theory,
whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
 
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

the Work and Derivative Works thereof.
 
"Contribution" shall mean any work of authorship, including
the original version of the Work and any modifications or additions
to that Work or Derivative Works thereof, that is intentionally
submitted to Licensor for inclusion in the Work by the copyright owner
or by an individual or Legal Entity authorized to submit on behalf of
the copyright owner. For the purposes of this definition, "submitted"
means any form of electronic, verbal, or written communication sent
to the Licensor or its representatives, including but not limited to
communication on electronic mailing lists, source code control systems,
and issue tracking systems that are managed by, or on behalf of, the
Licensor for the purpose of discussing and improving the Work, but
excluding communication that is conspicuously marked or otherwise
designated in writing by the copyright owner as "Not a Contribution."
 
"Contributor" shall mean Licensor and any individual or Legal Entity
on behalf of whom a Contribution has been received by Licensor and
subsequently incorporated within the Work.
 
2. Grant of Copyright License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
copyright license to reproduce, prepare Derivative Works of,
publicly display, publicly perform, sublicense, and distribute the
Work and such Derivative Works in Source or Object form.
 
3. Grant of Patent License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
 
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
 
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
 
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and
 
(c) You must retain, in the Source form of any Derivative Works
that You distribute, all copyright, patent, trademark, and
attribution notices from the Source form of the Work,
excluding those notices that do not pertain to any part of
the Derivative Works; and
 
(d) If the Work includes a "NOTICE" text file as part of its
distribution, then any Derivative Works that You distribute must
include a readable copy of the attribution notices contained
within such NOTICE file, excluding those notices that do not
pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
 
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
 
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
 
6. Trademarks. This License does not grant permission to use the trade
names, trademarks, service marks, or product names of the Licensor,
except as required for reasonable and customary use in describing the
origin of the Work and reproducing the content of the NOTICE file.
 
7. Disclaimer of Warranty. Unless required by applicable law or
agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the
appropriateness of using or redistributing the Work and assume any
risks associated with Your exercise of permissions under this License.
 
8. Limitation of Liability. In no event and under no legal theory,
whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
 
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.
