The draft defines a IANA registry with a list of identifiers for the WebRTC's statistics API with a set of RTCP SR, RR, and XR metrics related to the transport of multimedia flows. https://datatracker.ietf.org/doc/draft-ietf-xrblock-rtcweb-rtcp-xr-metrics/ <https://datatracker.ietf.org/doc/draft-ietf-xrblock-rtcweb-rtcp-xr-metrics/> Gist from the introduction of the draft: "The WebRTC Stats API currently lists metrics reported in the RTCP Sender and Receiver Report (SR/RR) [RFC3550] to fulfill this requirement. However, the basic metrics from RTCP SR/RR are not sufficient for precise quality monitoring, or diagnosing potential issues. In this document, we provide some guidelines on choosing additional RTP metrics for the WebRTC [W3C.WD-webrtc-20150210]. Furthermore, we create a registry containing metrics reported in RTCP XR." Any comments from the W3C WebRTC WG participants are welcome, they can be provided directly to the WG by sending your comments to xrblock@ietf.org <mailto:xrblock@ietf.org>. S.
