Here is the most recent version of the charter.  This is what we'll be
sending to the IESG for WG approval unless someone has any major
objections...

DESCRIPTION:

Routing table growth has been an issue of much concern.  Many have talked
about temporary methods to alleviate the drain on Internet resources.  In the
vein of these discussions, we started to consider aggregation and filtering
techniques to reduce the amount of routing information carried by routers with
global knowledge.

The purpose of the Prefix Taxonomy Ongoing Measurement & Inter Network
Experiment WG is to consider and measure the problem of routing table
growth and possible interim methods for reducing the impact of routing
table resource consumption within a network and the global Internet.  The
first step of the WG is to define the impacts on routing resource
consumption and to identify the problems facing routing scalability.

We believe the next step is to develop suggestions for filtering and
aggregating prefixes to reduce an individual networks routing table size
and route processing load and possible knobs with the least loss of
reachability if such methods are determined to be feasible in addressing
the problem.  This work may possibly define a framework for larger efforts
to address the problems facing interdomain routing scalability.

GOALS:

1) To provide a clear definition of the problems facing Internet
   Routing Scaling today.  This includes routing table size and route
   processing load.
2) To provide a taxonomy to describe prefix information for peer review.
3) To collate measurements of routing table scaling data and publish a
   reference list.
4) To discuss and document methods of filtering/aggregating prefix
   information and to discuss and document what support from protocols or
   vendor knobs that might be helpful in doing this.  In addition, to
   suggest policy guidelines to RIRs, LIRs and/or ISPs for
   allocations,etc. that may be useful.
5) To determine the long and short term effects of filtering/aggregating
   prefixes to reduce router resource consumption.
6) To develop methods of controlling policy information propagation in
   order to limit the need for propagation of prefix sub-aggregates.
