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

The Routing & Addressing directorate has been working on a strawman
problem statement since Prague. I just submitted our first cut as an
Internet Draft and it's available at:

http://www.cs.duke.edu/~narten/ietf/draft-narten-radir-problem- statement-00.txt

We would welcome comments on the document. In particular:

 - Do folk agree with the problem statement as written, or are we
   missing something fairly fundamental?

 - Are there other pressures on the routing system that we have not
   listed or described completely?

 - We intentionally did not include improving mobility as a core
   "problem", as explained in the document. (That doesn't mean we
   don't recognize that some of the solutions under discussion may
   also be applicable to mobility scenarios. Rather, we tend to see
   improved mobility as a possible benefit of certain classes of
   solutions.)

 - Are there other views of what folk perceive the core routing and
   addressing problem to be?
