CURRENT_MEETING_REPORT_ Reported by Martha Steenstrup/BBN Minutes of the Inter-Domain Policy Routing Working Group (IDPR) Summary 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. 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 flexibility 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 e-mail to idpr-wg-request@bbn.com. 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. Interested parties are encouraged 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. The IDPR discussion list should be included in 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. Comments should be submitted to the authors and to the IDPR discussion list. The IDPR Working Group Chair would like the MIB submitted 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 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.
