The IESG has approved the following document: - 'Considerations for Selecting RTCP Extended Report (XR) Metrics for the WebRTC Statistics API' (draft-ietf-xrblock-rtcweb-rtcp-xr-metrics-10.txt) as Informational RFC This document is the product of the Metric Blocks for use with RTCP's Extended Report Framework Working Group. The IESG contact persons are Adam Roach, Alexey Melnikov and Ben Campbell. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-xrblock-rtcweb-rtcp-xr-metrics/ Technical Summary: This document describes monitoring features related to media streams in Web real-time communication (WebRTC). It provides a list of RTCP Sender Report, Receiver Report and Extended Report metrics, which may need to be supported by RTP implementations in some diverse environments. For each of the metrics proposed, the document provides rational along with consideration when using them. Working Group Summary: A lot of effort went into how to ensure proposed metrics are referenced and used by WebRTC WG in W3C. There were no objection or questions about the usefulness of the metrics proposed but more so about ensuring implementors are aware and take full advantage of the metrics. Initially a registry was agreed to be the right way forward but after much debates, in order for better exposure to the implementing community, it was agreed that metrics defined in IETF are to be added to the specification within W3C and for this document to define initial proposed metrics along with how to add/expose future metrics useful to the WebRTC WG and surrounding community. The defined metrics here are already part of the W3C documents and the metrics proposed to be used by WebRTC are implemented and used in the wild. Personnel: The document shepherd is Shida Schubert. The responsible Area Director is Ben Campbell.
