Kaplan Oracle May 2014 Requirements for an End-to-End Session Identifier in IP-Based Multimedia Communication Networks Abstract This document specifies the requirements for an end-to-end session identifier in IP-based multimedia communication networks. This identifier would enable endpoints, intermediate devices, and management and monitoring systems to identify a session end-to-end across multiple SIP devices, hops, and administrative domains.

Informational [Page 2] RFC 7206 Requirements for End-to-End Session ID May 2014 1. Introduction IP-based multimedia communication systems like SIP [1] and H.323 [2] have the concept of a "call identifier" that is globally unique. The identifier is intended to represent an end-to-end communication session from the originating device to the terminating device. Such an identifier is useful for troubleshooting, session tracking, and so forth. Unfortunately, there are a number of factors that mean that theShow full document text
