Due to lack interest from the working group, this draft will be allowed to expire. We may reconsider this work in the future, depending on how the WebRTC approach of sending multiple types of media in a single RTP session works in practice.

This document specifies how multiple RTP sessions are to be multiplexed on the same lower-layer transport, e.g. a UDP flow. It discusses various requirements that have been raised and their feasibility, which results in a solution with a certain applicability. A solution is recommended and that solution is provided in more detail, including signalling and examples.
