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.
