Re: [RAM] First cut at routing & addressing problem statement

Hi Thomas,

Some minor comments on the draft:
Sec 4.7:
"For a large ISP, the internal IPv4 table can be between 50,000 and  
150,000 routes."
What do you mean by internal IPv4 table? In large IS, the number of  
routable prefixes in a router can easily reach 250k.

   The degree of interconnectedness between ASes has increased in recent
    years.  That is, the Internet as whole is becoming "flatter" with an
    increasing number of possible paths interconnecting sites [ref?]
http://www.cs.ucla.edu/~rveloso/papers/fp163_oliveira.pdf has some  
numbers for this in section 4.3.

Thanks,

--Ricardo
