Session Description Protocol Offer/Answer Clarifications for RTP/RTCP Multiplexing
RFC 8035, “Session Description Protocol Offer/Answer Clarifications for RTP/RTCP Multiplexing”, is a Proposed Standard document published in November 2016 by C. Holmberg. It updates RFC 5761. The canonical text is published by the RFC Editor.
Abstract
This document updates RFC 5761 by clarifying the SDP offer/answer negotiation of RTP and RTP Control Protocol (RTCP) multiplexing. It makes it clear that an answerer can only include an "a=rtcp-mux" attribute in a Session Description Protocol (SDP) answer if the associated SDP offer contained the attribute.
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.
