Multiplexing RTP Data and Control Packets on a Single Port

Colin Perkins and Magnus Westerlund

Internet Engineering Task Force, RFC 5761, April 2010.


This memo discusses issues that arise when multiplexing RTP data packets and RTP Control Protocol (RTCP) packets on a single UDP port. It updates RFC 3550 and RFC 3551 to describe when such multiplexing is and is not appropriate, and it explains how the Session Description Protocol (SDP) can be used to signal multiplexed sessions.
