1. Introduction - General recommendations

   This document is an extension to STD35, RFC 1006, a standard for the
   Internet community. The document does not duplicate the protocol

   implement ISO Transport Class 2 Non-use of Explicit Flow Control on
   top of TCP.

   The document should be used in conjunction with the RFC 1006 and ISO
   8073.
