Abstract
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).
