The IDPR working group met for a single session at the November IETF
in Houston.  The time was divided among a discussion of IDPR version
2, an excellent video on "Routing by Preference" from Yuko Murayama,
and IDPR working group business.

IDPR version 2 provides policy-based multicast and multipath routing
as well as policy-based resource allocation.  To support the features
of version 2, the IDPR protocols required only minor changes.
Specifically, the path control protocol, route generation procedure,
and routing information distribution protocol underwent minor
modifications.  An Internet Draft describing IDPR version 2 will be
available early in 1994.

However, the IDPR version 1 software for route generation and path
control required major redesign for version 2.  Ram Ramanathan and
Regina Rosales Hain described the software simplifications and
fleibility resulting from their redesigns.  Version 2 software will
begin rigorous testing in December.  To obtain a copy of the version 1
or version 2 software, please send email to [e-mail].

Routing by preference, as presented by Yuko Murayama of the WIDE
project in Japan, involves selecting routes that factor in both source
and destination preferences, such as which domains are unfavorable and
the type of route preferred through unfavorable domains.  The example
of "preference" presented in the video was to take the shortest
(minimum delay) paths through unfavorable domains.  I encourage you to
read the paper on routing by preference submitted to the list by Yuko
and to write to her about suggestions for solutions to the problem
presented.  Please include idpr-wg in your responses, as the problem
is of interest to the group.

There are two updated Internet Drafts available concerning IDPR: one
is the MIB and the other is the DNS support for IDPR.  Please read
them and submit comments to the authors and to idpr-wg.  I would like
the working group to submit the MIB as a Proposed Standard.

The IDPR working group will suspend for the time being.  We have
accomplished all that we can without an independent version 1
implementation.  We plan to resume either when there exists an
independent implementation of IDPR version 1 or when the version 2
Internet Draft becomes available, whichever occurs first.

In the meantime, the working group mailing list will remain open to
handle the unfinished business of the updated Internet Drafts and to
discuss issues relevant to IDPR.
