          Wednesday dinner, fix meeting of new IAB to elect chair, fix 1st teleconference, IAB voting rules)

        Christian, Phill, Lixia, Paul, Steve are leaving…
        thanks for the their years of great service!

        Chair election meeting after Thursday plenary; Brian Carpenter is willing to continue as chair; other candidates should make their interest known to Abel Weinrib before Thursday.

        IESG liaison–Yakov is willing to continue; other candidates should make their interest known to Brian Carpenter before Thursday.

        The IAB “voting rule” was not clear. After some discussion, the following was agreed to as approximating the ideal of consensus while removing single-individual veto power:

          The IAB agreed that where the IAB takes a decision, that decision requires the support of at least seven voting members of the board, and no more than one dissenting vote.
          This will be in effect until a revised version of RFC 1601 has been approved.

      4. vote on new IETF chair and IESG slate

        Both chair and slate were approved.

      5. D.Perkins appeal – final preparation for open hearing

        We are ready.

      6. IAB/IRTF/IETF futures discussion, and preparation for open meeting

        An opinionated member of the community recently said that while individual members of the IAB add a lot of value to the IETF, the IAB as a body contributes only marginally to the community. In addition, the IRTF is invisible, and some people have a big problem with research groups being closed. The second point led to a long and somewhat heated discussion about whether research groups should be closed or open. Points made included that closed groups run counter to the values of the community; that the IPng directorate seemed to work even though it was closed, but it did publish minutes and mailing list for interested people and was perceived as being part of elected IESG; and that on the other hand, IRTF groups demand long term attention, and have vague enough goals to benefit from having the group closed.

        It became apparent that there was general agreement that to be an effective part of the community, the IRTF needs to institute regular reporting of activities and progress of research groups. This could be accomplished through regular posting of status and meeting reports to the Web, open meetings of research groups at IETF meetings, etc.

        In addition, it was agreed that there is value in having one or more architectural groups that are concerned with broad architectural issues that often cross IESG areas but are still critical for the future Internet. One suggestion is to start out by putting in place a review process with area directors.

      7. Architecture issues

        IAB and IPv6, IPv4 Balkanization (Lixia)

        Lixia Zhang presented a short talk questioning why the IAB is not taking on driving the transition to IPv6. She argued that the IPv4 address space is running out *now*, not ten years

        from now as indicated by some allocation curves; that the allocation curves do not even closely reflect the true Internet growth; and that a scarce address space is an unstable state to be in and we must move out of it as soon as possible. NAT boxes may serve as temporary solutions, but should not be the permanent architectural design.

        Lixia argued that, because of the exponential growth of the Internet, the earlier we transition to IPv6, the cheaper. Therefore, the IAB should explain to the community the inevitability of the transition and the danger for waiting too long. The two major reasons against promoting IPv6:

        1. “IPv6 does not solve the routing table crisis”, and
        2. “Wait 5 more years and then we will have IPv7 developed”,

        are both incorrect. For (1), we need a separate effort to handle the current routing table issue; IPv6 has a potential to provide long term solutions. And (2) is from some people who argue for fundamentally changing the current datagram architecture (and hopefully IAB is not buying into that).

        Lixia closed with her recommendation for actions of the IAB:

        • Publish an informational RFC to clearly endorse IPv6 and urge the community to plan the transition ASAP.
        • Solve the routing problem with a separate effort.
        • Reiterate the principle that globally unique addresses are a fundamental piece of the architecture.

        After Lixia’s presentation, there was a heated exchange on these topics. The chair suggested that Lixia send the list of recommended actions to IAB mailing list for future discussion at the next teleconference.

        Is RSVP deployable?

        Here, the issue is the difference in difficulty between intra-enterprise vs. inter-enterprise deployment. A fundamental issue is the economics that will apply to the full Internet.

        It was proposed that the IAB review both the RSVP specification and the Multimedia Multiparty Session Control (mmusic) Working Group’s architecture specification.

Future Meetings
