CURRENT_MEETING_REPORT_ Reported by Ralph Droms/ Bucknell DHC Minutes The meeting began with a presentation from Bill Nowicki of Legato about Legato's ``Network Resource Administration Platform''. Bill prefaced his talk with the statement that, while our Working Group is solving the low level problems associated with dynamic naming and addressing, his talk would cover more high level issues. The platform he described is intended to ease the use and management of network facilities for a running system. The remainder of the meeting concentrated on Jeff Mogul's ``Proposal for Supporting IP Address Assignment Using Coordinated BOOTP Servers''. Jeff has written up the IP address allocation and delivery mechanism as discussed at the June meeting in Palo Alto (see the PSC Proceedings for details). A copy of Jeff's proposal is available for anonymous FTP on sol.bucknell.edu in file dhcwg/mogul.prop. The discussion raised several specific questions about the proposed protocol: o The protocol must not require a server on each subnet. o There should be a new response ``No IP address available''. o A client can release an IP address back to the IP address server - can the client also clear ARP caches of any references to that client? o How can a client find out that its IP address has been reallocated after a network partition heals? o Rather than periodically pinging a host to verify that its IP address is still in use, the IP address servers should only check when IP addresses need to be reused. o We need to write into the protocol description something about the eventual use of multicast. Steve Deering was good enough to go through the Host Requirements RFC and generate a list of per network and per interface parameters. He wondered if we should consider any of these as part of the dynamic host configuration protocol: Per network parameters: Gateway forwarding on/off Non-local source routing on/off Policy filters for non-local source routing (list) 1 Maximum reassembly size integer Default TTL integer PMTU aging timeout integer Per interface parameters: Perform mask discovery on/off Be a mask supplier on/off Perform router discovery on/off Router solicitation multicast address (multicast address) Ignore router discovery on/off Default router list (addresses and preferences) Static routes: destination (host/subnet/net) mask (subnet mask) type of service integer first hop router (address) ignore redirects on/off PMTU integer perform PMTU discovery on/off Attendees Karl Auerbach auerbach@csl.sri.com Richard Basch probe@mit.edu Scott Bradner sob@harvard.harvard.edu Andrew Cherenson arc@sgi.com Steve Deering deering@pescadero.stanford.edu Tom Evans wcc@cup.portal.com Karen Frisa karen@kinetics.com Robert Gilligan gilligan@sun.com Yong Guo guo@cs.ubc.ca Steven Hubert hubert@cac.washington.edu Holly Knight holly@apple.com Gregory Lauer glauer@bbn.com John Leong john.leong@andrew.cmu.edu Paul McKenney mckenney@sri.com Lynn Monsanto Robert Morgan morgan@jessica.stanford.edu Bill Nowicki nowicki@sun.com Frank Slaughter fgs@shiva.com John Veizades veizades@apple.com Walter Wimer ww0n+@andrew.cmu.edu Denis Yaro DYARO@SUN.COM 2
