A new Request for Comments is now available in online RFC libraries. RFC 3409 Title: Lower Layer Guidelines for Robust RTP/UDP/IP Header Compression Author(s): K. Svanbro Status: Informational Date: December 2002 Mailbox: email@example.com Pages: 11 Characters: 25815 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-rohc-rtp-lower-layer-guidelines-03.txt URL: ftp://ftp.rfc-editor.org/in-notes/rfc3409.txt This document describes lower layer guidelines for robust header compression (ROHC) and the requirements ROHC puts on lower layers. The purpose of this document is to support the incorporation of robust header compression algorithms, as specified in the ROHC working group, into different systems such as those specified by Third Generation Partnership Project (3GPP), 3GPP Project 2 (3GPP2), European Technical Standards Institute (ETSI), etc. This document covers only lower layer guidelines for compression of RTP/UDP/IP and UDP/IP headers as specified in [RFC3095]. Both general guidelines and guidelines specific for cellular systems are discussed in this document. This document is a product of the Robust Header Compression Working Group of the IETF.
