This document defines the Extended Report (XR) packet type for the
RTP Control Protocol (RTCP), and defines how the use of XR packets
can be signaled by an application if it employs the Session
Description Protocol (SDP). XR packets are composed of report
blocks, and seven block types are defined here. The purpose of the
extended reporting format is to convey information that supplements
the six statistics that are contained in the report blocks used by
RTCP's Sender Report (SR) and Receiver Report (RR) packets. Some
applications, such as multicast inference of network characteristics
(MINC) or voice over IP (VoIP) monitoring, require other and more
detailed statistics. In addition to the block types defined here,
additional block types may be defined in the future by adhering to
the framework that this document provides.
This document is a product of the Audio/Video Transport Working Group
of the IETF.
This is now a Proposed Standard Protocol.
This document specifies an Internet standards track protocol for
