RTP Control Protocol (RTCP) Extended Report (XR) for Bytes Discarded
Metric
draft-ietf-xrblock-rtcp-xr-bytes-discarded-metric-02
Abstract
The RTP Control Protocol (RTCP) is used in conjunction with the Real-
time Transport Protocol (RTP) in to provide a variety of short-term
and long-term reception statistics. The available reporting may
include aggregate information across longer periods of time as well
as individual packet reporting. This document specifies a report
computing the bytes discarded from the de-jitter buffer after
successful reception.
