Geoff Huston has prepared a thoughtful essay about Internet routing, based on his participation in a recent IAB workshop on the subject.

I attended a Internet Architecture Board workshop in October 2006 on the topic of routing and addressing, and in this column I'd like to report on the impressions on this topic that I took away from this workshop. I should note at the outset that this is not in any way an official report of the meeting, nor even a report of my impressions of the presentations and the related workshop discussion. This article could best be described as my reactions to what I heard at this workshop and what I think they might imply in the area of routing and addressing.

... as we look forward some rather tough questions tend to reveal themselves.

The published report on the 1998 workshop is RFC 2902.
