A top AS and top prefix talkers would be really useful.
Flowscan will do the top AS, out of the box.
It could be hacked to go further.

v6 relays and locations as seen from various major ASes.

Blech. :) (For comparison, here's the IPv4 traceroute:
Very interesting. From the east coast your IPv4 traffic
goes to Virginia and then to the UK. But your IPv6 traffic
goes to Atlanta, Houston, LA and across the Pacific.
Is this due to someone's misconfiguration of weights?
--Michael

I don't see him saying that we should do nothing. There
seems to be general consensus among these guys that
the time for action is now. If you want the IPv6 transition
to be painless for your company, then you need to get
planning and get IPv6 in your test labs today.
--Michael Dillon
with
the same kind of technology imperatives as the larger ones.
--Michael Dillon
in place by this time so that IPv4 addresses can be returned
and recycled.
--Michael Dillon
around this by selling the networks
that use the IPv4 addresses, but then you are getting
away from the realm of commodities. A commodity is a
fairly generic product and networks are far from generic.

different source.
If you agree with the Cisco IP Journal article then we have
to engage our collective brains *NOW* to plan and test
and be ready for the day when we need to do things differently.

they willing to release funds for?
In fact, they will probably ask you to justify those new
boxes and when you dig into it you will likely find that

network where every driver(packet) is free to detour around

Remember the information highway?
--Michael Dillon
is to develop
more sophisticated interconnect variants such as MPLS VPN interconnects
and CDN or multicast interconnects.
--Michael Dillon
. The solution is to
use binding arbitration clauses in all interconnect agreements
whether settlement-free, paid peering or settlement-based.
--Michael Dillon
and politics of
business does tend to gum up the works a bit now that
there is no serious threat of global nuclear war.
--Michael Dillon
such equality between peering partners
is rare. It's really about the business case for settlement
free interconnect and that is rather more complex than
merely the choice between free traffic exchange and
paid transit.
--Michael Dillon
P.S. would the Internet be worse off if all traffic
exchange
customers. And if the existing customers of L3 and
Cogent are experiencing agony, what kind of marketing story
does that tell?
--Michael Dillon
their respective customers as part of the *customer's* bandwidth bill.
Perhaps someone wants to make this argument before a judge
in order to set a legal precedent for mandatory peering
with settlements?
--Michael Dillon
on netflow
data from peering interconnects combined with the the average
bandwidth price on each companies top ten customer contracts
would add very little cost to computing the settlement amount.
I don't advocate one way or another. But I do expect to
see things change when there is instability.
