Miscellaneous Capabilities Negotiation in the Session Description Protocol
RFC 7006, “Miscellaneous Capabilities Negotiation in the Session Description Protocol”, is a Proposed Standard document published in September 2013 by M. Garcia-Martin, S. Veikkolainen, R. Gilman. The canonical text is published by the RFC Editor.
Abstract
The Session Description Protocol (SDP) has been extended with a capability negotiation mechanism framework that allows the endpoints to negotiate transport protocols and attributes. This framework has been extended with a media capabilities negotiation mechanism that allows endpoints to negotiate additional media-related capabilities. This negotiation is embedded into the widely used SDP offer/answer procedures.
This memo extends the SDP capability negotiation framework to allow endpoints to negotiate three additional SDP capabilities. In particular, this memo provides a mechanism to negotiate bandwidth ("b=" line), connection data ("c=" line), and session or media titles ("i=" line for each session or media).
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
