ISO Transport Service on top of TCP (ITOT)
Status of the Memo
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state
and status of this protocol. Distribution of this memo is unlimited.
Abstract
This document is a revision to STD35, RFC 1006 written by Marshall T.
Rose and Dwight E. Cass. Since the release of RFC 1006 in May 1987,
much experience has been gained in using ISO transport services on
top of TCP. This document refines the protocol and will eventually
supersede RFC 1006.
This document describes the mechanism to allow ISO Transport Services
to run over TCP over IPv4 or IPv6. It also defines a number of new
features, which are not provided in RFC 1006.
The goal of this version is to minimise the number of changes to
RFC 1006 and ISO 8073 transport protocol definitions, while maximising
performance, extending its applicability and protecting the installed
base of RFC 1006 users.
