Area report for the IETF Routing Area June 1996 IETF meeting InterDomain Routing (IDR) - Sue Hares and Yakov Rekhter chairs Status of Documents since last IETF: - Confederations (forwarded to Experimental) - Communities (forwarded to Proposed Standard) [draft-ietf-idr- community-00.txt] - Usage of Communities (forward to Informational RFC) (title: An Application of the BGP Community Attribute in Multi-home Routing) [draft-ietf-idr-community-usage.txt] - Route Reflection (forwarded to Experimental) [draft-ietf-idr-route-reflect-00.txt] - IDRP for IP v4 and v6 - Draft publish by Paul comments made on draft. Configuring IDRP Confederations will be folded into this document. Discussion will continue on the mailing list. - How new BGP Attribute Types are defined", B. Manning, 04/12/1996. (3209 bytes) Will be released as a IDRP draft and final call will be made on the mailing list. Documents not discussed: MIB - still awaiting usage reports New items: MED Calculation in BGP (Rich Woundy) Discussion on the mailing list will occur. Initial informaition gathering into a document by Susan Hares. BGP Route Calculation Support for RSVP This document was presented by Bill since it was not available. Suggestions to author were explain why, and what in full detail. Open Issues from last Meeting: 1) BGP MIB - operational reports 2) Working Group needs to discuss Route-Reflection and Route Server Specification and chose one of the specification IP Routing for Wireless/Mobile Hosts (mobileip) Jim Solomon and Erik Nordmark chairs The mobileip working group met twice in Montreal. The first meeting discussed the latest IPv6 draft. After much debate it was decided that Mobile IPv6 requires no changes to the base IPv6 protocol documents. However, it was agreed that all IPv6 nodes SHOULD implement a binding cache and that all IPv6 routers SHOULD be home agents. The required mobility support in routers was discussed but no resolution was reached; hopefully this will be resolved on the mailing list. The second meeting focussed on IPv4 mobility and centered around security and firewall traversal issues. Authenticated firewall traversal has become one of the key required components needed for ubiquitous Internet-wide mobility and the WG is likely to focus on these security issues in addition to the IPv6 work. Regarding the Internet Key Management protocol being developed by the ipsec working group, it was noted that the ability to separate the source IP address in a packet (e.g. care-of address) from the "identity" of an entity (e.g. home address) is helpful (if not mandatory) to facilitate firewall traversal by mobile nodes. Open Shortest Path First IGP (ospf) John Moy chair The OSPF WG met for a single session on Wednesday, June 26 1930-2200 in Montreal. We started with a review of the current state of the OSPF for IPv4 and IPv6 drafts. Ran Atkinson then gave a presentation of the use of IPv4-compatible addresses within IPv6. Sandra Murphy presented the changes made in "Digital Signatures for OSPF" since her last draft, along with implementation experience. The session ended with two QoS routing presentations, the first an overview of QoS requirements from Raj Nair and Bala Rajagopalan, and then a description of QOSPF by Eric Crawley New Internet Routing and Addressing Architecture (nimrod) Noel Chiappa, Isidro Castineyra and David Bridgham chairs Steve Kent presented work on securing Nimrod against denial of service attacks. The group discussed the work, but no actions were taken. While route generation is outside of the core Nimrod design, it is obviously a necessary piece to actually using Nimrod. Ram Ramanathan talked about the route generation algorithm in BBN's experimental Nimrod implementation. Martha Steenstrup gave a presentation of how some of the ideas of Nimrod are finding application in mobile wireless work they're doing. Martha also talked about lessons learned while implementing Nimrod and Ram continued with particular lessons learned about Nimrod's maps. Even with small, experimental maps it became obvious that a lot more work needs to be done here to make Nimrod's maps usable by the general networking community. Also, map information interacts closely with route generation algorithms so the two may not be as separable in practice as they are in the architecture. At the end there was a short discussion on the future of Nimrod as the BBN Nimrod project is over and the experimental code will be released. Inter-Domain Multicast Routing (IDMR) Anthony Ballardie and Bill Fenner chairs The PIM and CBT protocol specifications are undergoing final revisions before being submitted for Experimental standard status. In addition, five IDMR MIBs have been put forward for Experimental, but first must be reviewed by a member of the Network Management area. The group was solicited for any final comments on the specs and/or MIBs. The following presentations were given: - an overview of a hierarchical multicast architecture, and accompanying transition strategy for evolving the MBONE - PIM updates, including PIM border router behaviour for PIM clouds to interoperate with dense mode protocols. - DVMRPv3 update - IGMP version 3 update - Some QoS issues relating to IDMR - A heuristic for lower-cost multicast routing (a scheme integrated with M-OSPF for producing lower-cost multicast trees) Mobile Ad-hoc Networking (manet) BOF Joseph Macker, M. Scott Corson, and Stephen Batsell chairs A proposed charter for a working group in the area of mobile ad-hoc networking was introduced and discussed. Difficulties with existing protocols in mobile scenarios were briefly discussed, and three candidate protocols were presented that have the potential to provide efficient routing solutions in ad-hoc mobile networks. It was decided that the scope of the working group charter be narrowly focused on unicast routing, with any future work being built upon the unicast results. If a working group is formed, initial Internet-Drafts discussing each protocol will be available prior to the December IETF. Unidirectional Link Routing (udlr) BOF Walid Dabbous chair During the BoF session there were a presentation of the general problem of integrating unidirectional links in the Internet, then two presentations from INRIA and Hughes concerning respective proposed solutions. There were also a presentation of the WIDE Internet project and a short presentation on link layer considerations. Then the discussions focused on comparing both INRIA and Hughes solutions which are both being implemented and expected to be tested during the next six months. There were a general feeling that we need to carry on the implementations, discuss the results of both solutions on the mailing list and have another BoF session in San Jose's meeting. Quality of Service Routing (qosr) BOF Eric Crawley and Ross Callon chairs The QoSR BoF met for one sesson on Friday, June 28th from 0900 to 1130. The BoF was surprisingly well attended (for a Friday morning) with 144 people signing the roster, indicating quite a bit of interest in the subject of Quality of Service Routing. Presentations on the general issues for QoS Routing were delivered and discussed in the group. It was determined that general architecture and requirements for QoS Routing are needed to focus on the areas where changes and additions to protocols may be necessary. A mailing list will be established to continue the dialog.
