Connection-Oriented Media Transport in SDP draft-ietf-mmusic-sdp-comedia-01.txt David Yon
Changes since comedia-00 ! Removed SCTP from list of protocols (another draft) ! Added RFC 2119 definitions ! Expanded source information: nettype addr-type unicast-address port ! Added clarifications on connection setup rules ! Added clarifications on Bidirectional vs Unidirectional Media ! Added caveat about NAT and source information ! Added new “reuse” direction attribute David Yon - Dialout.Net, Inc. 2
Issues Is direction:reuse specified correctly? ! Routing of SIP INVITE can lead to ambiguity when renegotiating a session Possible Solutions: ! Endpoints assume that they are free to reuse an existing connection. ! Get rid of reuse. ! Make reuse be an optional qualifier of the direction rather than a type of direction. For example: direction:passive reuse direction:active reuse IN IP4 10.1.1.1 1892 David Yon - Dialout.Net, Inc. 3
Future Proposed Next Steps ! Ready for Last Call? David Yon - Dialout.Net, Inc. 4
