IAB Wireless Workshop BOF (iww) Thursday, March 30 at 0900-1130 =============================== CHAIRS: Brian Carpenter Fred Baker Bob Hinden DESCRIPTION: Wireless technology, including wireless LANs, data transfer over cellular radio (GSM, 3GPP, etc), and mobile operations from aircraft and near earth spacecraft are becoming increasingly important. Some market projections suggest that a mobile Internet in parallel with or augmenting the wired Internet may be comparable in size to the wired Internet as early as 2003. The wireless operators have not, however, chosen to use IP4, TCP, full HTTP/HTML, and other applications for a variety of reasons. These relate to edge device cost, bandwidth limitations, perceived protocol imperfections, unnecessary complexities, the chattiness of the application protocols, and network layer addressing issues. Unfortunately, this creates some serious issues at the wired/wireless demarcation: end to end operation is sacrificed, security is compromised, and automated content modification in some form becomes necessary. The IAB considers these to be serious fundamental issues, which will in time be a serious impediment to the usability of the combined Internet if not addressed. The IAB, on Feb 29-March 2, held an invitational workshop, hosted by Bob Hinden at Nokia. The workshop was to discuss this, determine what the legitimate issues are, and make recommendations to the wireless operators, IRTF, and IETF on the architectural road map for the next few years. The fundamental question addressed is "what are the issues, and what really needs to be done to unify the Internet below the application layer." Applications will also need to be addressed, but were perceived to be more than could be usefully discussed in a three-day workshop, and probably require different expertise. The intent of this BOF is to present a preliminary report on the results, and discuss that report.
