Technical Summary
This addition to the Session Description Protocol (SDP) allows an SDP offer to
contain more than one network address associated with a single offered media
stream. The motivation for this is IPv6 transition - it allows a dual-stack
client to offer both an IPv6 and an IPv4 address from which the answerer can
choose. It also allows these addresses to be prioritized, so an offerer can
indicate that they would prefer to connect via IPv6, if possible. This has
significant applicability to the Interactive Connectivity Establishment (ICE)
mechanism being developed in MMUSIC.
Working Group Summary
The MMUSIC working group supported the advancement of this document. A concern
was expressed that interaction of other media grouping semantics in SDP was
insufficiently specified, but the media grouping framework was authored by some
f the same individuals who wrote this document, and they seem to feel that the
distinction is clear enough.
Protocol Quality
This specification was reviewed for the IESG by Jon Peterson.
