The IESG has approved the following document: - 'RTP Control Protocol (RTCP) Extended Report (XR) Block for Discard Count metric Reporting' (draft-ietf-xrblock-rtcp-xr-discard-15.txt) as Proposed Standard This document is the product of the Metric Blocks for use with RTCP's Extended Report Framework Working Group. The IESG contact persons are Gonzalo Camarillo and Richard Barnes. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-xrblock-rtcp-xr-discard/ Technical Summary This draft defines a new block type to augment those defined in [RFC3611] for use in a range of RTP applications. The new block type supports the reporting of the per-packet report metric capturing individual packets discarded from the jitter buffer after successful reception. Working Group Summary There were several points of debate within the working group; however, none were particularly rough and authors and commentators came up with the text that resolves any issues thus consensus was achieved in all cases. There was a long debate on discard type for "both" (discard type indicating a combination of different discard type). After long debate the WG concluded to remove this ambiguous discard type and clarified how one should report when there are multiple reasons why report packet was discarded. Document Quality This document has been reviewed by numerous people within XRBLOCK and through two rounds of WGLCs the document resolved any outstanding issues. The document has been reviewed by SDP directorate post WGLC for SDP extensions defined, some issues surrounding clarity of how the extension is used was raised but was resolved. The document has been submitted to performance metric directorate for a review prior to this draft being submitted for IESG review. Personnel Shida Schubert is the Document Shepherd. Gonzalo Camarillo is the Responsible Area Director.
