Signaling Compression
RFC 3320, “Signaling Compression”, is a Proposed Standard document published in January 2003 by R. Price, C. Bormann, J. Christoffersson, H. Hannu, Z. Liu, J. Rosenberg. It has since been updated by RFC 4896. The canonical text is published by the RFC Editor.
Abstract
This document defines SigComp, a solution for compressing messages generated by application protocols such as SIP [RFC-2543] and RTSP [RFC-2326]. The architecture and pre-requisites of SigComp are outlined, along with the format of the SigComp message. Decompression functionality for SigComp is provided by a 'Universal Decompressor Virtual Machine' 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].
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
