Multicast Acquisition Report Block Type for
RTP Control Protocol (RTCP) Extended Reports (XRs)
Abstract
In most RTP-based multicast applications, the RTP source sends inter-
related data. Due to this interdependency, randomly joining RTP
receivers usually cannot start consuming the multicast data right
after they join the session. Thus, they often experience a random
acquisition delay. An RTP receiver can use one or more different
approaches to achieve rapid acquisition. Yet, due to various
factors, performance of the rapid acquisition methods usually varies.
Furthermore, in some cases, the RTP receiver can do a simple
multicast join (in other cases, it is compelled to do so). For
quality reporting, monitoring, and diagnostic purposes, it is
important to collect detailed information from the RTP receivers
about their acquisition and presentation experiences. This document
addresses this issue by defining a new report block type, called the
Multicast Acquisition (MA) report block, within the framework of RTP
Control Protocol (RTCP) Extended Reports (XRs) (RFC 3611). This
document also defines the necessary signaling of the new MA report
block type in the Session Description Protocol (SDP).
