New draft agenda for routing wg at RIPE 48
by Joao Damas 03 May '04

03 May '04

** Note: due to changes in speakers' plans the routing wg will only use the first slot (Wednesday morning, 9:00-10:30) RIPE 48 Amsterdam Routing Working Group Session 5-May-2004 2nd Draft Agenda A. Preliminaries (Joao Damas) - introduction - participants' list - volunteering of scribe - jabber/irc interface - agenda bashing - RIPE 47 minutes - actions from earlier meetings B. John Bender & Dan Bowman, Boeing: Global network mobility (25 min) C. Goetz Lichtwald, Universität Karlsruhe: Routing Workshop report (20 min) D. Matthew Williams, RIPE NCC: RIS update (20 min) E. Carlos Friacas, FCCN: Raising RPSLng awareness Y. General I/O with Other WGs Z. AOB Additional information: Talk B. ------- Author: John Bender (JHB42-RIPE) Speakers: John Bender and Don Bowman Topic: Implementing Global Network Mobility using BGP-4 Abstract: Traditional approaches to IP mobility target host mobility, rather than mobile networks per se. Providing internet access on mobile platforms where hosts (which may number in the hundreds) remain relatively stationary with regards to the platform presents a set of problems that has not been addressed by traditional IP mobility solutions. This presentation describes a technique that allows intercontinental mobility of networks aboard aircraft that does not require either any modifications to the TCP/IP protocol stacks of the hosts on board the aircraft, or interaction from the end-user of this device. Mobility is accomplished by means of selective advertising and withdrawing prefixes at satellite earth stations as aircraft transit the globe. We expect that this topic will be of interest to all service providers as our actions impact the global routing table.
