Editor's Note: Minutes received 12/14/92 CURRENT_MEETING_REPORT_ Reported by Philip Almquist/Consultant Minutes of the Selection Criteria BOF (SELECT) The objective of the Selection Criteria BOF was to develop consensus on a precise statement of the community's goals for a replacement for IP. The goal was to provide a yardstick against which the various proposals could be objectively measured to point up their relative strengths and weaknesses. Needless to say, this goal was far too ambitious to actually be achievable in the single session available. The BOF began with a discussion two previously written documents that presented goals for the new IP: o draft-partridge-ipv7-criteria-00.txt (Partridge/Kastenholz) o draft-iab-ipversion7-00.txt (IAB) The two sets of goals were compared and contrasted. Craig Partridge and Barry Leiner verbally clarified and presented additional rationale for the goals presented in those papers. Lively discussion ensued, during which the Group modified the list of goals from the Partridge/Kastenholz paper. In particular, the goals of architectural simplicity and globally unique identification of endpoints from the IAB's list were thought to be important enough to be added. Some participants pointed out that it was also important to add topological flexibility as a goal, noting that we certainly needed to understand whether any of the proposed next generation IP's would preclude topologies currently in use. Others pointed out that, although it may be hard to quantify, the proposals may embody differing amounts of technological risk, and that our criteria needed therefore to address risk. Some felt that performance needed to be a goal. Matt Mathis pointed out that different proposals may differ in how the pain of deployment is allocated among the levels of the networking food chain (backbones, midlevels, campus nets, end users), and emphasized that we are unlikely to successfully deploy any proposal in which some level receives little benefit from the new version of IP yet is expected to shoulder a large chunk of the pain. Finally, a number of people felt that IETF change control and freely available specifications have been critical to the success of the current IP, and that it is therefore important to consider to what extent each of the proposals preserves those features. The goal of providing usage accounting was dropped from the list of goals when it was pointed out that the accounting requirements specified in the Partridge/Kastenholz paper would be trivially met by any proposal. Having come to a reasonable amount of consensus on a list of goals, the BOF then set about the task of trying to rank them in terms of importance. No real consensus was attained. Perhaps the best way to 1 summarize the conclusions of this part of the meeting is to say that whatever is chosen as an IP replacement must solve the scaling problem and must not be substantially inferior to the current IP in terms of other important attributes (security, manageability, robustness, etc.). A third task, trying to refine each of the goals on the list into a statement of sufficient detail and precision that the extent to which a particular proposal met the goal could be fairly objectively determined, was skipped due to lack of time. Craig Partridge and Frank Kastenholz agreed to revise their Internet-Draft to attempt to incorporate the results of the BOF.
