Abstract

This document is an extension to STD35, RFC1006, a standard for the Internet community. The document does not duplicate the protocol definitions contained in RFC1006 and in International Standard ISO 8073. It supplements that information with the description of how to implement ISO Transport Class 2 Non-use of Explicit Flow Control on top of TCP. This memo provides information for the Internet community. This memo does not specify an Internet standard of any kind.

1. Introduction - General recommendations

This document is an extension to STD35, RFC1006, a standard for the Internet community. The document does not duplicate the protocol definitions contained in RFC1006 and in International Standard ISO 8073. It supplements that information with the description of how to implement ISO Transport Class 2 Non-use of Explicit Flow Control on top of TCP.

The document should be used in conjunction with the RFC1006 and ISO 8073.

The RFC1006 standard defines how to implement ISO 8073 Transport Class 0 on top of TCP. This memo defines how to implement ISO 8073 Transport Class 2 Non-use of Explicit Flow Control on top of TCP. Like ISO Transport Class 0, Class 2 Non-use of Explicit Flow Control provides basic connection with minimal overhead.

A Transport protocol class is selected for a particular Transport connection based upon the characteristics of the lower layers and the

requirements of the upper layer. Use of class 2 Non-use of Explicit Flow Control is suitable when the use of separate virtual data channels for normal and expedited Data are desirable or when an explicit disconnection of the Transport connection is desirable.

Hosts which choose to implement this extension are expected to listen on the well-known TCP port number 399.

It is recommended that the well-known RFC1006 TCP port 102 not be used. This recommendation is done to minimise impact to an existing RFC1006 implementation.

The memo also describes the use of this extension within the DIGITAL Network Architecture (DNA).

2. The protocol

The protocol specified by this memo is fundamentally equivalent to the protocol ISO 8073 Transport Class 2 Non-use of Explicit Flow Control, with the following extensions:

- Expedited Data service is supported.

- Splitti...
