Title : Marking and Selectively Retransmitting High-Priority Packets in the Real-Time Transport Protocol (RTP)
Author(s) : J. Lennox
Filename : draft-lennox-avt-recoverable-packets-00.txt
Pages : 15

In some circumstances, it is useful and desirable for the sender of
an RTP stream to be able to deliver a subset of its RTP packets
reliably. One example of this is a video codec which can encode a
video stream such that decoder state can be maintained using just a
subset of the packets encoded. However, existing RTP reliability
mechanisms only define mechanisms which retransmit all the packets of
an RTP stream.
This document describes a mechanism by which the sender of an RTP
stream can mark a subset of the packets of an RTP stream as high-
priority recoverable packets, and by which the receiver of the stream
can request retransmission of the high-priority packets.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
