BOF DESCRIPTION

---------------

 The IAB arranged a workshop in October, 2006 to focus on routing and addressing
 issues [0]. This workshop identified scalability problems in the global routing
 system. The research community is working to map the overall design space and
 understand the tradeoffs between the different solutions. This work happens in
 the Routing Research Group (RRG). The solutions discovered so far have interesting
 behaviours that are not fully understood by mere desk analysis. For instance,
 some of the solutions have packet reordering and delay implications that may
 affect higher layers. Some have MTU implications for large parts of the Internet.
 Most solutions require deployment of new nodes, and the incentive models for
 deploying them are not entirely clear.

 LISP and the LISP Alternative Topology mapping system (ALT) is one solution in
 the overall design space, under the general category of "map-and-encapsulate"
 mechanisms. The purpose of this BOF is to form an Exploratory Group (RFC 5111)
 at the IETF. The group will host discussions and documents necessary to perform
 experiments that help the community understand how the above behaviors are effected
 by LISP and ALT

The expected outputs are:

- document(s) that describe open issues where experimentation
  may be helpful,
- document(s) that describe planned experiments and results thereof,
  and
- experimental protocol specifications (exp, June 2009)

 As an Exploratory Group, this group has a finite lifetime of 18 months. At the end
 of those 18 months, and depending on the outcome of the experiments and the design
 work from the RRG, the group may either be terminated or rechartered. The group
 shall also:

 - clearly label its results as experimental
 - avoid design discussions that are within the scope of the RRG,
 - refrain from spending significant amount of time on the well
   understood parts of map-and-encapsulate mechanisms
 - demonstrate commitment to focus on experiments before
   submitting any protocol specifications for publication
   as RFCs

 This group is only focused on LISP and ALT. Some results may apply to other
 designs as well, such as solutions involving a similar mapping system but a
 different encapsulation scheme. But this is not guaranteed. If other proposals
 surface from the research community with equally interesting questions that would
 benefit from similar experimentation, future groups can be created for that
 purpose, as long as there appears to be sufficient interest in the community for
 such work. The interest is demonstrated via XXX independent implementation efforts.
