Number of providers

[Matthew Luckie <mjl () caida org>]

Based on feedback we have received at http://as-rank.caida.org/ we are 
in the process of updating our AS relationship inference algorithm.

We're interested to know how many providers different ASes have based on 
their size.  We assume that it changes with size of the AS, e.g. Tier-1 
have zero.

We would appreciate it if anyone who is willing to provide us with their 
AS number and the number of their providers, would email this 
information to mjl () caida org.

p.s. It would be great if you could also tell us who your providers are.
