It would be great if we could shift focus and think about the
operations impact of depeering vs. just the political and/or
contractual ramifications.
Have there been any proposals put forth to the NANOG PC to review
this highly visible depeering at the NANOG meeting this month?
Aside from anything else, there is this interesting topic
on the agenda:
Abstract: NetFlow-based Traffic Analysis Techniques for Peering Networks
Richard Steenbergen, nLayer Communications, and Nathan Patrick, Sonic.net
Seems to me that a discussion of traffic analysis could
handle a slide or two on actual impacts of this depeering.

in the past, we (renesys) have done reports on the impact on global
routing from various kinds of internet (and extra-internet) events,
like the 9121 leak of the full table last year, the 2003 blackouts in
the northeastern US, and the landfall of hurricane katrina.
i've made a suggestion to the PC that we would be willing to do a
quick report on the (3)/Cogent situation, purely from a routing
perspective, if there is interest. the idea would be to lay some
facts to the speculation from a routing perspective:
size/# of singly homed downstreams of each
apparent weight/utilization of the edge between them
timeline
impact of the disconnection (what paths gained the most)
that sort of thing. put some context to this as seen from a fairly
large peerset (we can mix in routeviews and ripe ris peers if
necessary, too). if nov 9 is a serious re-de-peering date, it might be
interesting to have some of these facts in evidence beforehand.
is there interest in something like this for oct nanog? are there
facts other than those mentioned above that people would like to see
reported on (and that can be seen from routing tables--we don't have
traffic data and most people who do won't give them up for public
viewing).
i don't want to waste time preparing it if people are over it already,
but would be happy to do something if there is interest.
