End-to-End Session Identification in IP-Based Multimedia Communication Networks
RFC 7989, “End-to-End Session Identification in IP-Based Multimedia Communication Networks”, is a Proposed Standard document published in October 2016 by P. Jones, G. Salgueiro, C. Pearce, P. Giralt. It obsoletes RFC 7329. The canonical text is published by the RFC Editor.
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 the Session Initiation Protocol (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.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
