 RTP Control Protocol (RTCP) Extended Report (XR) Block for Independent
                 Reporting of Burst/Gap Discard Metric
          draft-ietf-xrblock-independent-burst-gap-discard-02

Abstract

   This document defines an RTP Control Protocol (RTCP) Extended Report
   (XR) block that allows the reporting of burst and gap discard metrics
   independently of the burst and gap loss metrics for use in a range of
   RTP applications.

1.  Introduction

1.1.  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 dejitter buffer at the receiver.
   The number of packets discarded depends on the dejitter buffer
