RFC 8079 Title: Guidelines for End-to-End Support of the RTP Control Protocol (RTCP) in Back-to-Back User Agents (B2BUAs) Author: L. Miniero, S. Garcia Murillo, V. Pascual Status: Standards Track Stream: IETF Date: February 2017 Mailbox: lorenzo@meetecho.com, sergio.garcia.murillo@gmail.com, victor.pascual.avila@oracle.com Pages: 16 Characters: 41687 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-straw-b2bua-rtcp-17.txt URL: https://www.rfc-editor.org/info/rfc8079 DOI: 10.17487/RFC8079 SIP Back-to-Back User Agents (B2BUAs) are often designed to also be on the media path, rather than just to intercept signalling. This means that B2BUAs often implement an RTP or RTP Control Protocol (RTCP) stack as well, thus leading to separate multimedia sessions that the B2BUA correlates and bridges together. If not disciplined, this behaviour can severely impact the communication experience, especially when statistics and feedback information contained in RTCP messages get lost because of mismatches in the reported data. This document defines the proper behaviour B2BUAs should follow when acting on both the signalling plane and media plane in order to preserve the end-to-end functionality of RTCP. This document is a product of the Sip Traversal Required for Applications to Work Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol.
