RTP provides end-to-end network transport functions suitable for
applications transmitting real-time data, such as audio, video or
simulation data, over multicast or unicast network services.  RTP
does not address resource reservation and does not guarantee
quality-of-service for real-time services.  The data transport is
augmented by a control protocol (RTCP) to allow monitoring of the
data delivery in a manner scalable to large multicast networks, and
to provide minimal control and identification functionality.  RTP and
RTCP are designed to be independent of the underlying transport and
network layers.  The protocol supports the use of RTP-level
translators and mixers.
