Tier 2 rents from Tier 1, Tier 3 rents from Tier 2...isn't it?

Hi,
Thanks.
Yes, that sounds logical and fine. My question remains: Tier 1 must be at
the core of the network (in this case the Internet). Can a Kenyan ISP, even

Kenyan-scale?"
Are you working with UUNET?
Thanks.

Thanks Howard. I had just been wondering about this very topic myself. You
plugged one of your books, but I learned a lot about this same topic from
another one of your books, which I will plug! :-)

I might even add that a few companies have described themselves as
"tier 0", with the idea that they will dynamically select best routes
based on real-time measurements. I get nervous about that, as we have
enough instabilities caused by too-frequent change in the global
routing system.
