Real Time Control Protocol attribute in Session Description Protocol
RFC 3605, “Real Time Control Protocol attribute in Session Description Protocol”, is a Proposed Standard document published in October 2003 by C. Huitema. The canonical text is published by the RFC Editor.
Abstract
The Session Description Protocol (SDP) is used to describe the parameters of media streams used in multimedia sessions. When a session requires multiple ports, SDP assumes that these ports have consecutive numbers. However, when the session crosses a network address translation device that also uses port mapping, the ordering of ports can be destroyed by the translation. To handle this, we propose an extension attribute to SDP.
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.
