The Great Exchange

Wed May 27 20:55:46 UTC 1998

On the international slide, I've seen a slide presentation from
Deutche Telecom that said that half of all of its traffic stayed 
in country, which *I'd* label as "local".

This is all WAG, tho.  I'll argue that you can never measure this
accurately from the network (how much traffic did you *not* count?,
how much traffic was delivered on campus?  is the site multihomed?), 
you have to measure it from the edge.

To really test this you need sampling from the users, ala the Nielson 
method and knowledge of geography for IP addresses.  Market opportunity 
anyone?
