Technical Summary

This memo expands and clarifies the behavior of Real-time Transport 
Protocol (RTP) endpoints that use multiple synchronization sources 
(SSRCs).  This occurs, for example, when an endpoint sends multiple 
media streams in a single RTP session.  This memo updates RFC 3550 with 
regards to handling multiple SSRCs per endpoint in RTP sessions,  with a 
particular focus on RTCP behavior.  It also updates RFC 4585 to update 
and clarify the calculation of the timeout of SSRCs and the inclusion of 
feedback messages.
