ISO Presentation Services
on top of TCP/IP-based internets
Status of this Memo
This memo proposes a standard for the Internet community.
Distribution of this memo is unlimited.
1. Introduction
[RFC 1006] describes a mechanism for providing the ISO transport
service on top of the Transmission Control Protocol (TCP) [RFC 793]
and Internet Protocol (IP) [RFC 791]. Once this method is applied,
one may implement "real" ISO applications on top of TCP/IP-based
internets, by simply implementing OSI session, presentation, and
application services on top of the transport service access point
which is provided on top of the TCP. Although straight-forward,
there are some environments in which the richness provided by the OSI
application layer is desired, but it is nonetheless impractical to
implement the underlying OSI infrastructure (i.e., the presentation,
session, and transport services on top of the TCP). This memo
describes an approach for providing "stream-lined" support of OSI
application services on top of TCP/IP-based internets for such
constrained environments.
2. Terminology
In as much as this memo is concerned primarily with concepts defined
in the framework of Open Systems Interconnection (OSI) as promulgated
by the International Organization for Standardization (ISO), the
terminology used herein is intended to be entirely consistent within
that domain of discourse. This perspective is being taken despite
the expressed intent of implementing the mechanism proposed by this
memo in the Internet and other TCP/IP-based internets. For those
more familiar with the terminology used in this latter domain, the
author is apologetic but unyielding.
Although no substitute for the "correct" definitions given in the
appropriate ISO documents, here is a short summary of the terms used
herein.
