RFC3605 · Real Time Control Protocol (RTCP) attribute in Session Description Protocol (SDP)

Real Time Control Protocol (RTCP) attribute in Session Description Protocol (SDP)

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.
