Greetings MMUSIC Below you will find our proposed charter update for MMUSIC. Please let us know if you have any questions or comments. Thanks Flemming & Bo (MMUSIC co-chairs) <charter> The Multiparty MUltimedia SessIon Control (MMUSIC) Working Group was originally chartered to develop protocols to support Internet teleconferencing and multimedia communications. These protocols are now reasonably mature, and many have received widespread deployment. Currently, the group is focused on using and negotiating media streams with the Session Description Protocol (SDP), which is used as a common protocol to express media and session descriptions. The group also maintains the Real-time Streaming Protocol (RTSP) specifications. The group has revised these protocols in the light of implementation experience and additional demands that have arisen from other WGs (such as AVTCORE, CLUE, ICE, and RTCWEB). In particular, the many uses of SDP have led to requests for numerous extensions as well as a recognition of several limitations in the original protocol design. Today, the SDP protocol is widely deployed and continues to see extensions being defined. The current aims of the working group include the following: - Provide SDP signaling support for the Interactive Connectivity Establishment (ICE) protocol and its extensions. These were originally defined in MMUSIC, but are now handled by the ICE WG. - To support the establishment of multi-party multimedia sessions for RTCWEB based implementations, MMUSIC provides SDP signaling support for a number of extensions required by RTCWEB. The MMUSIC WG will seek a balanced trade-off between general applicability of such extensions versus RTCWEB specific usage. - Various other extensions to SDP may be pursued to remedy the most urgent of SDP's shortcomings. These include updates to the SDP specification itself and missing IANA registrations. - With the exception of the items listed above, only extensions within the existing SDP framework will be done. - Maintain the specification of the (revised) Real Time Streaming Protocol (RTSP) as needed. The MMUSIC work items will be pursued in close coordination with other IETF WGs including AVTCORE, CLUE, ICE, RTCWEB and SIPCORE, as well as others where appropriate.
