This memo specifies how Explicit Congestion Notification (ECN) can be
used with the Real-time Transport Protocol (RTP) running over UDP,
using the RTP Control Protocol (RTCP) as a feedback mechanism. It
defines a new RTCP Extended Report (XR) block for periodic ECN
feedback, a new RTCP transport feedback message for timely reporting
of congestion events, and a Session Traversal Utilities for NAT
(STUN) extension used in the optional initialisation method using
Interactive Connectivity Establishment (ICE). Signalling and
procedures for negotiation of capabilities and initialisation methods
are also defined.
