Re: Definition of Tier-1

what's cool is that andre found that there
is some natural `tiering' of ASes just according
to (almost any topological) quantitative connectivity metrics
        http://www.caida.org/~broido/bgp/asoutdeg.html
(math-heavy, no ASes identified, just illustrates that 
tiering has some sense manifested in real data, 
which i think is pretty cool)

        .... To be sure, mathematics can be extended to 
        any branch of knowledge, including economics, 
        provided the concepts are so clearly defined 
        as to permit accurate symbolic representation. 
        That is only another way of saying that in some 
        branches of discourse it is desirable to know
        what you are talking about.
