 End-to-End Session Identification in IP-Based Multimedia Communication
                                Networks
                    draft-ietf-insipid-session-id-26

Abstract

   This document describes an end-to-end Session Identifier for use in
   IP-based multimedia communication systems that enables endpoints,
   intermediary devices, and management systems to identify a session
   end-to-end, associate multiple endpoints with a given multipoint
   conference, track communication sessions when they are redirected,
   and associate one or more media flows with a given communication
   session.  While the identifier is intended to work across multiple
   protocols, this document describes its usage in SIP.

   This document also describes a backwards compatibility mechanism for
   an existing session identifier implementation (RFC 7329) that is
   sufficiently different from the procedures defined in this document.

   This document obsoletes RFC 7329.
