This document defines Signaling Compression (SigComp), a solution for
compressing messages generated by application protocols such as the
Session Initiation Protocol (SIP) (RFC 3261) and the Real Time
Streaming Protocol (RTSP) (RFC 2326).  The architecture and
prerequisites of SigComp are outlined, along with the format of the
SigComp message.

Decompression functionality for SigComp is provided by a Universal
Decompressor Virtual Machine (UDVM) optimized for the task of running
decompression algorithms.  The UDVM can be configured to understand
the output of many well-known compressors such as DEFLATE (RFC-1951).

This document is a product of 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.
