RTP Control Protocol (RTCP) Extended Report (XR) Block
for Independent Reporting of Burst/Gap Discard Metrics
Abstract
This document defines an RTP Control Protocol (RTCP) Extended Report
(XR) block that allows the reporting of burst/gap discard metrics
independently of the burst/gap loss metrics for use in a range of RTP
applications.

RFC 8015 RTCP XR Burst/Gap Discard November 2016
1. Introduction
1.1. Independent Burst/Gap Discard Metrics Block
This document defines a new block type that extends the metrics
defined in [RFC7003]. The new block type reports the proportion of
packets discarded in a burst by the de-jitter buffer at the receiver.
The number of packets discarded depends on the de-jitter buffer
algorithm implemented by the endpoint.
