This memo defines a mechanism to allow multiple RTP sessions to be multiplexed onto a single lower-layer transport flow (e.g., onto a single UDP 5-tuple). Requirements for multiplexing RTP sessions are discussed, along with the trade-off between the different options. A shim-based multiplexing layer is proposed, along with associated signalling.
