Introduction 1.1. Burst/Gap Discard Metrics Block This document defines a new block type to augment those defined in [RFC3611] for use in a range of RTP applications. The new block type supports the reporting of the proportion of packets discarded by the jitter buffer at the receiver, using packet discard logic according to the jitter buffer algorithms. The discards during discard bursts are reported, together with the number of bursts. This block is intended to be used in conjunction with [RFC7002], which provides the total packets discarded and on which this block therefore depends. However, the metric in [RFC7002] may be used independently of the metrics in this block. This block provides information on transient IP problems. Burst/gap metrics are typically used in cumulative reports; however, they also may be used in interval reports (see the Interval Metric flag in Section 3.2). The burstiness of packet discard affects userShow full document text
