The IESG has approved the following document: - 'Guidelines for Use of the RTP Monitoring Framework' (draft-ietf-avtcore-monarch-22.txt) as Informational RFC This document is the product of the Audio/Video Transport Core Maintenance Working Group. The IESG contact persons are Robert Sparks and Gonzalo Camarillo. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-avtcore-monarch/ Technical Summary This memo describes the extensible RTP monitoring framework for using RTP Control Protocol (RTCP) with new RTCP Extended Reports (XR) block type to report new metrics regarding media transmission or reception quality. In this framework, any new XR block should contain a single metric or a small number of metrics relevant to a single parameter of interest or concern, rather than containing a number of metrics which attempt to provide full coverage of all those parameters of concern to a specific application. Applications may then "mix and match" to create a set of blocks which covers their set of concerns. Where possible, a specific block should be designed to be re-usable across more than one application, for example, for all of voice, streaming audio and video. Working Group Summary This document was jointly last called with XRBLOCK WG, one of the primary consumer of these architectural considerations. It was significantly rewritten as the result of the AD review as it didn't meet the goals of an architecture specificaiton, and was more focused on the issues which the WG had come to consensus on. The changes has been WG last called and consensus exist for moving forward with these changes. Document Quality There are ongoing usage of the principles for extensions described in this document within the XRBLOCK WG. The document has been reviewed by a number of people in both AVTCORE and XRBLOCK WG. The AD found a significant scope problem which has been resolved. Personnel Magnus Westerlund is the Document Shepherd. The Responsible Area Director is Robert Sparks.
