Description of Working Group:
The Multiparty MUltimedia SessIon Control (MMUSIC) Working Group (WG) is
chartered to develop Internet standards track protocols to support
Internet teleconferencing sessions. MMUSIC's focus is on supporting the
loosely-controlled conferences that are pervasive on the MBone today.
However, the WG also will ensure that its protocols are general enough
to be used in managing tightly-controlled sessions.
To date, MMUSIC has drafted protocols for:
- distributing session descriptions -- Session Description Protocol
(SDP) and Session Announcement Protocol (SAP),
- providing security for session announcements -- SAP Security,
- controlling on-demand delivery of real-time data -- Real-Time Stream
Protocol (RTSP),
- initiating sessions and inviting users -- Session Initiation Protocol
(SIP), and
- managing tightly-controlled sessions -- Simple Conference Control
Protocol (SCCP).
In addition, the WG has drafted two informational documents: the first
describes the architectural framework for MMUSIC, and the second
describes interoperability scenarios for ITU- and Internet-based
teleconferencing systems.
The WG's protocols reflect coordination with other IETF efforts related
to multimedia conferencing (e.g., AVT, RSVP). In addition, the WG will
collaborate with liaisons to ITU standards bodies and industry
consortiums as appropriate to ensure interoperable standards (e.g.,
SIP/SAP/SDP with ITU H.323 and H.332).
The WG has defined two sets of goals -- immediate goals to be
accomplished over the next several months, and longer-term goals which
will be reviewed and possibly revised after the immediate goals are met.
The immediate goals include bringing several protocols to Proposed
Standard (SDP, RTSP), or Experimental RFC status (SAP), and to produce
Informational RFCs for the informational drafts listed above. The
longer-term goals are to bring the remaining protocols to Proposed
Standard status (SIP, SAP Security, SAP), to investigate the
requirements for a next-generation session description protocol, and to
continue the development of SCCP.
