- 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.
