1. Introduction
1.1. Burst and Gap Loss Report Block
This draft 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 lost by the
network. The losses during loss bursts are reported, together with
the number of bursts and additional data allowing the calculation of
statistical parameters (mean and variance) of the distribution of
