- Area Summary reported by Bob Hinden/Sun
-
- Border Gateway Working Group (BGP
-
- The BGP Working Group agreed to make minor editorial changes to the
- BGP-4 draft and reissue it with the proposed changes. The BGP-4 MIB
- will be amended to remove potential conflicts with BGP-3 MIB.
-
- The Group met with SIP/IPAE Working Group members to discuss how BGP-4
- could be modified to accommodate SIP/IPAE inter-domain routing. The BGP
- Working Group recommended to the SIP/IPAE Group that it is preferable to
- not change BGP-4 to support SIP/IPAE routing, rather it is preferable to
- explore the possibility of using IDRP to carry SIP/IPAE routing
- information.
-
- Inter-Domain Policy Routing Working Group (IDPR)
-
- The IDPR Working Group met for two sessions on Monday. The Chair gave a
- status report, describing the GATED development effort, DNS
- modifications, IDPR MIB, and the scheduled Internet pilot installation.
- Following the status report, the IDPR working Group focussed on the
- following issues:
-
-
- 1. How to get a software development team assembled to enable keeping
- the GATED effort going, independent of funding from individual
- sponsors.
-
- 2. What IDPR issues to pursue during the next year. For example,
- hierarchical addressing and host specification of source policy
- will likely be requested in the near future.
-
- 3. Conduct a survey of the policy needs of the Internet community,
- including the needs of transit service providers and the needs of
- users, to determine how IDPR meets these project needs.
-
- 4. Multicasting in the policy routing environment. The Group has a
- strawman proposal for this and intends to produce an Internet-Draft
- this spring, describing the proposal.
-
-
- IP Over Large Public Data Networks (IPLPDN)
-
- The Working Group discussed a revision to RFC 1294 ``Multiprotocol over
-
- 1
-
-
-
-
-
- Frame Relay''. The Group agreed to the following changes:
-
-
- o Specification of the padding of encapsulated protocols to a two
- byte address.
-
- o Discussion of remote bridging and clarification of bridge PDU
- encapsulation.
-
- o Inclusion of connection oriented protocols in an appendix.
-
-
- After an email review, the Working Group plans to submit the draft to
- the IESG as a Draft Standard.
-
- The Group discussed RFC 1356 on Multiprotocol over X.25 and agreed to
- collect information on implementation experience and to then submit it
- the IESG as a Draft Standard.
-
- The ``Directed ARP'' draft was reviewed again by the Group and the their
- previous plan to recommend this as a Proposed Standard was reversed.
- The Working Group will recommend to the authors that it be published as
- an Experimental Protocol.
-
- Work on IP over Circuit ISDN progressed with the following decisions:
-
-
- o X.25 was approved as an additional encapsulation protocol.
- o Multi-link transport was added. This will also be discussed with
- the PPP Extensions Working Group.
-
-
- In addition, the Working Group will write an informational RFC
- describing the IEEE 802.6i Draft Standard on remote bridging over SMDS.
-
- Open Shortest Path First (OSPF)
-
- The Working Group started a last call for four documents:
-
-
- 1. Updated OSPF V2 spec (backward-compatible bug fixes to RFC 1247)
- 2. Updated OSPF MIB
- 3. OSPF NSSA area option
- 4. OSPF Trap MIB
-
-
- The Working Group expects to submit these in the next month or two for
- publication as RFCs. continued discussion of a proposed
- user/implementation guide for OSPF over Frame relay networks (no
- protocol changes are actually required), and came to general agreement
- on a strategy for gracefully dealing with OSPF database overflow.

- Mobile IP Working Group (MOBILEIP)
-
- The Mobile IP Working Group met twice. The first session consisted of
- presentations by Pierre Dupont on current packet radio offerings from
- Motorola, by Tatsuya Ohnishi on a new mobile IP proposal from
- Matsushita, by Fumio Teraoka on recent changes to the Sony mobile IP
- proposal, and by Charlie Perkins of IBM on a more general architecture
- and terminology for mobility support in connectionless network
- protocols.
-
- The second session consisted of a talk by John Ioannidis on security and
- authentication extensions to the Columbia mobile IP proposal, and
- discussion of a number of new topics, including: agreement to submit
- all mobile IP proposals as Internet-Drafts, identification of multicast
- issues that arise with mobile hosts, the value of location-independent
- ``EIDs'' for supporting mobility, and the possible specification of a
- general ``destination has moved'' ICMP message to reduce the incidence
- of ``triangular routing'' in some mobile IP schemes.
-
- Multicast OSPF Working Group (MOSPF)
-
- The MOSPF Working Group decided to submit the Multicast OSPF Extensions
- draft as a Proposed Standard. They also decided to submit as a Proposed
- Standard a short document specifying how to map IP multicast addresses
- to a Token Ring Functional Address. The Group discussed possible
- designs of a multicast traceroute facility. Greg Minshall and Steve
- Deering agreed to write a concrete proposal.
-
- Source Demand Routing Protocol BOF (SDRP)
-
- The SDRP BOF decided to form a Working Group. A Charter for the Group
- was proposed, discussed and accepted. Work priorities were established
- and a schedule of work was generated. SDRP's capabilities and future
- goals were discussed. The mailing list will be established as
- sdrp-request@caldera.usc.edu.
-
- Virtual Circuit Routing BOF (VCROUT)
-
- The Virtual Circuit Routing BOF meeting to discuss adapting internet
- routing protocols for use in virtual circuit networks. The scope of the
- vc-routing work was covered including:
-
-
- o VC-routing architecture
- o Protocols to implement the architecture
- o Class of service
- o Multicast
- o Private logical networks
- o Internal switch addressing
- o Switch to network address (ie IP) translation.
- o VC setup protocol
-

-
-
-
-
- The Group concluded that the VC routing work should focus on using
- existing protocols and existing standards work to the extent possible.
-
- The BOF reviewed and discussed several items from a previous meeting
- that was held at NET during INTEROP week. These included the following:
-
-
- Scale The IGP should scale up to 1000 switches.
- Switch Addressing The switch ID being a 32-bit address that can
- either be an IP address or be mapped into an IP
- address.
- IGP OSPF/RMP was discussed as a possibility for the IGP.
- Inter-Domain Routing IDRP may be a good choice for this solution.
- Signaling Use Q.93B (ATM)/Q.933 (FR) as the base for virtual
- circuit management with potentially a few
- modifications. The Group will attempt to define an
- inter-switch call set up protocol that will include
- an option to do inter-domain and intra-domain source
- route call setup.
- Class Of Service Discussed the potential of 3 classes of service:
- VC (PVC and SVC) Datagram ``Soft VC'' (similar to VC
- but would not have the strict quality guarantees
- provided by VC.)
- Address Resolution There were a few issues considered that fall under
- the heading of address resolution including
- ``network level'' address to switch/port address
- resolution.
-
-
- The Group decided that there was sufficient interest to form an IETF
- working group to continue this work.
