This document defines a ROHC (Robust Header Compression) profile for
compression of IP/UDP/RTP (Internet Protocol/User Datagram
Protocol/Real-Time Transport Protocol) packets, utilizing
functionality provided by the lower layers to increase compression
efficiency by completely eliminating the header for most packets
during optimal operation.  The profile is built as an extension to
the ROHC RTP profile.  It defines additional mechanisms needed in
ROHC, states requirements on the assisting layer to guarantee
transparency, and specifies general logic for compression and
decompression related to the usage of the header-free packet
format.  This document is a replacement for RFC 3242, which it
obsoletes.

This document is a product of the Robust Header Compression Working
Group of the IETF.

This is now a Proposed Standard Protocol.

This document specifies an Internet standards track protocol for
the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the
"Internet Official Protocol Standards" (STD 1) for the
standardization state and status of this protocol.  Distribution
of this memo is unlimited.
