Price Status: Informational Date: January 2003 Mailbox: hans.hannu@epl.ericsson.se, jan.christoffersson@epl.ericsson.se, StefanForsgren@alvishagglunds.se, kcleung@eee.hku.hk, zhigang.c.liu@nokia.com, richard.price@roke.co.uk Pages: 19 Characters: 39433 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-rohc-sigcomp-extended-04.txt URL: ftp://ftp.rfc-editor.org/in-notes/rfc3321.txt This document describes how to implement certain mechanisms in Signaling Compression (SigComp), RFC 3320, which can significantly improve the compression efficiency compared to using simple per-message compression. SigComp uses a Universal Decompressor Virtual Machine (UDVM) for decompression, and the mechanisms described in this document are possible to implement using the UDVM instructions defined in RFC 3320.
