Considerations for Selecting RTP Control Protocol (RTCP) Extended Report (XR) Metrics for the WebRTC Statistics API
draft-ietf-xrblock-rtcweb-rtcp-xr-metrics-10
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.
