This is a revised agenda for the robust header compression BOF to be held today Tuesday. As this is the night of the social event, we will ignore the break and instead aim to finish 17.45 at the latest. ------------- Robust Header compression BOF (robhc) Tuesday, November 9 at 1545-1800 ========== CHAIRS: Mikael Degermark <micke@cdt.luth.se> Stephen Pink <steve@sics.se> DESCRIPTION: The cellular community is now standardizing the next generation cellular systems. These systems will use IP to deliver telephony to coming mobile phones, to allow end-to-end IP telephony. As cellular bandwith is expensive, radio spectrum efficiency is of outmost importance and thus the IP/UDP/RTP headers must be compressed over the air. 3GPP has specified the requirements for the needed header compression scheme and it has been shown that no current header compression scheme in the IETF can satisfy these requirements. CRTP [RFC-2508] is the closest candidate but is not sufficiently robust against errors on the link, i.e., CRTP cannot deliver acceptable performance at the anticipated error rates. It is likely that the number of users of cellular IP telephony will be larger than the current number of people using TCP/IP, therefore it is important that a suitable header compression scheme is developed. The BOF will outline the relevant properties of the cellular links, the requirements, and will explain why CRTP fails. One or more proposals for a suitable header compression scheme will be presented, and finally we will discuss if and how the IETF will work on standardizing a suitable header compression scheme. AGENDA 0. Introduction Mikael Degermark 1. 3GPP timeline Mats Nilsson 2. 3GPP requirements on robust header compression. Khiem Le, Nokia draft-degermark-hc-requirements-00.txt 3. Why CRTP is not good enough Mikael Degermark draft-degermark-crtp-eval-00.{ps,txt} 4. Cellular link properties affecting header compression - delays, error rates & error distributions for EDGE, WCDMA, GSM, etc. Krister Svanbro, Ericsson 5. RObust Checksum-based header COmpression - ROCCO Lars-Erik Jonsson, Ericsson draft-jonsson-robust-hc-02.{ps,txt} 6. Should we propose that a WG is formed? Outline of charter presented.
