Metric Blocks for use with RTCP's Extended Report Framework (xrblock) --------------------------------------------------------------------- Charter Last Modified: 2011-12-09 Current Status: Active Working Group Chair(s): Charles Eckel Shida Schubert Real-time Applications and Infrastructure Area Director(s): Gonzalo Camarillo Robert Sparks Real-time Applications and Infrastructure Area Advisor: Gonzalo Camarillo Mailing Lists: General Discussion:xrblock@ietf.org To Subscribe: https://www.ietf.org/mailman/listinfo/xrblock Archive: http://www.ietf.org/mail-archive/web/xrblock/index.html Description of Working Group: RFC3611, "RTP Control Protocol Extended Reports (RTCP XR)" established a framework to allow new information to be conveyed in RTCP, supplementing the original report blocks defined in RFC 3550, "RTP: A Transport Protocol for Real-Time Applications". The XRBLOCK working group is chartered to work within this framework, evaluating proposals for report block definitions containing new metrics. The group will follow the guidelines established in RFC5968, "Guidelines for Extending the RTP Control Protocol (RTCP)" and RTP Monitoring Architecture being developed in the AVTCORE working group. The group will consider the guidelines for performance metric development currently being discussed in the PMOL working group. Goals and Milestones: Feb 2012 Submit RTCP XR Report Block for Measurement Identity Reporting to IESG Apr 2012 Submit RTCP XR Report Block for Delay metric Reporting to IESG Apr 2012 Submit RTCP XR Report Block for Packet Delay Variation Metric Reporting to IESG Jun 2012 Submit RTCP XR Report Block for Discard metric Reporting to IESG Jun 2012 Submit RTCP XR Report Block for Burst/Gap Discard metric Reporting to IESG Jun 2012 Submit RTCP XR Report Block for Burst/Gap Loss metric Reporting to IESG Aug 2012 Submit RTCP XR Report Block for Run Length Encodings of Discarded Packets to IESG Oct 2012 Submit RTCP XR Report Block for QoE Metrics Reporting to IESG Oct 2012 Submit RTCP XR Report Block for Concealed Seconds metric Reporting to IESG Dec 2012 Submit RTCP XR Report Block for Jitter Buffer Metric Reporting to IESG Dec 2012 Submit RTCP XR Report Block for Loss Concealment metric Reporting to IESG Internet-Drafts: Posted Revised I-D Title ------ ------- -------------------------------------------- Oct 2011 Dec 2011 RTCP XR Report Block for Packet Delay Variation Metric Reporting Oct 2011 Jan 2012 Measurement Identity and information Reporting using SDES item and XR Block Oct 2011 Dec 2011 RTCP XR Report Block for Delay metric Reporting Oct 2011 Jan 2012 RTCP XR Report Block for Burst/Gap Loss metric Reporting Oct 2011 Jan 2012 RTCP XR Report Block for Burst/Gap Discard metric Reporting Oct 2011 Dec 2011 RTCP XR Report Block for Discard metric Reporting Nov 2011 Feb 2012 Real-time Transport Control Protocol (RTCP) Extension Report (XR) for Run Length Encoding of Discarded Packets Feb 2012 Feb 2012 RTCP XR Blocks for QoE Metric Reporting Request For Comments: None to date.
