              Session Identification Registration (SESSID)

Status of this Memo

      This document is an Internet-Draft and is in full conformance with
   all provisions of Section 10 or RFC 2026.  Internet-Drafts are
   working documents of the Internet Engineering Task Force (IETF), its
   areas, and its working groups.  Note that other groups may also
   distribute working documents as Internet-Drafts.

      Internet-Drafts are draft documents valid for a maximum of six
   months and may be updated, replaced, or obsoleted by other documents
   at any time.  It is inappropriate to use Internet-Drafts as reference
   material or to cite them other than as 'work in progress'.

Abstract

      This memo describes Session Id Registration that provides the
   ability for one (listening) Application Server to indicate that a
   session should be established with another (accepting) Application
   Server for connection- and transaction-oriented messaging the in SS7
   Signalling User Adaptation Layers [M3UA, SUA09, TUA01].  Extension
   parameters and procedures are added by this memo in extension to
   those of the User Adaptation layers to provide a closer model to that
   of the XNS/XTI interfaces, where one interface may be designated as a
   `listener' and another designated as an `acceptor'.  This permits ISO
   compliant interfaces for SCCP to maintain the same semantic for SUA
   and TUA.
