 RTP Control Protocol (RTCP) Extended Report (XR) Block for Independent
                 Reporting of Burst/Gap Discard Metric
          draft-ietf-xrblock-independent-burst-gap-discard-00

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 metrics in this report block can be used in
   a range of RTP applications.  The new block type reports the
   proportion of packets discarded by the jitter buffer at the receiver
   in a burst and number of packets discarded depends on the de-jitter
   buffer algorithm implemented by the endpoint.

   The new report block defined in this document is different from the
