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).
