It provides a list of RTP Control Protocol (RTCP) Sender Report (SR), Receiver Report (RR), and Extended Report (XR) metrics, which may need to be supported by RTP implementations in some diverse environments. It lists a set of identifiers for the WebRTC's statistics API. These identifiers are a set of RTCP SR, RR, and XR metrics related to the transport of multimedia flows. This document is a product of the Metric Blocks for use with RTCP's Extended Report Framework Working Group of the IETF. INFORMATIONAL: This memo provides information for the Internet community.
