The Session Initiation Protocol and Session Description Protocol Static Dictionary for Signaling Compression
RFC 3485, “The Session Initiation Protocol and Session Description Protocol Static Dictionary for Signaling Compression”, is a Proposed Standard document published in March 2003 by M. Garcia-Martin, C. Bormann, J. Ott, R. Price, A. B. Roach. It has since been updated by RFC 4896. The canonical text is published by the RFC Editor.
Abstract
The Session Initiation Protocol (SIP) is a text-based protocol for initiating and managing communication sessions. The protocol can be compressed by using Signaling Compression (SigComp). Similarly, the Session Description Protocol (SDP) is a text-based protocol intended for describing multimedia sessions for the purposes of session announcement, session invitation, and other forms of multimedia session initiation. This memo defines the SIP/SDP-specific static dictionary that SigComp may use in order to achieve higher efficiency. The dictionary is compression algorithm independent. [STANDARDS-TRACK]
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.
