RFC 6222: Guidelines for Choosing RTP Control Protocol (RTCP) Canonical Names (CNAMEs)

This RFC has been replaced. Do not implement against it for new work — it was formally obsoleted by RFC 7022.

Current version: RFC 7022Guidelines for Choosing RTP Control Protocol (RTCP) Canonical Names (CNAMEs)

In plain English — editorial summary, not part of the RFC

The RTP Control Protocol (RTCP) Canonical Name (CNAME) is a persistent transport-level identifier for an RTP endpoint. While the Synchronization Source (SSRC) identifier of an RTP endpoint may change if a collision is detected or when the RTP application is restarted, its RTCP CNAME is meant to stay unchanged, so that RTP endpoints can be uniquely identified and associated with their RTP media streams. For proper functionality, RTCP CNAMEs should be unique within the participants of an RTP session. However, the existing guidelines for choosing the RTCP CNAME provided in the RTP standard are insufficient to achieve this uniqueness. This memo updates those guidelines to allow endpoints to choose unique RTCP CNAMEs. [STANDARDS-TRACK]
