Subject: New draft on "SIP/SDP Overlap with RTSP"
Hello,
A new draft has been uploaded titled "SIP/SDP Overlap with RTSP" (draft-lindquist-mmusic-sip-rtsp-00). The draft is co-signed by Jan Lindquist, Jouni Maenpaa, Priya Rajagopal and Xavier Marjou. A slot is requested in MMUSIC for the July Stockholm meeting to present the draft.

For your convenience here is the abstract taken from the draft.
The Session Initiation Protocol (SIP) is widely used for establishing
multimedia sessions, whereas the Real Time Streaming Protocol (RTSP)
is a protocol for use in streaming media systems. RTSP has a dual
role: it establishes a media session for the delivery of streaming
media as well as controls the streaming session once it has been set
up. Since RTSP is also used for session establishment, there exists
an overlap between the functionality provided by SIP and RTSP. In
this document, we analyze a model in which SIP and the SDP offer/
answer model are used to set up a streaming session with an RTSP
control channel and one or more media delivery streams. Such a model
is beneficial since it allows the reuse of current architecture and
functionality (e.g., authentication, charging, and QoS) established
around SIP also for RTSP-based streaming.
If there are any questions or comments on the new draft we will be glad to answer them.
Best Regards,
Jan Lindquist
