Header Compression has proven to be essential for using RTP over
bandwidth limited links. While all of these links have only a
limited bandwidth, some are additional extremely unreliable, e.g.
wireless links. It is shown, that existing Header Compression
schemes, that work well over reliable links, perform very bad, if
many errors occur.
This led to the development of a new robust Header Compression
mechanism, that is introduced in this paper. The core idea is the
definition of update packets, which are referenced by non-update
packets. This reduces the interdependency between the packets and
with this the amount of discarded packets at the decompressor.
The Header Compression scheme, the used packet formats and the
decompression algorithm, are described in detail.

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.

implementation to automatically retrieve the ASCII version of the
