AOL & Cogent

I love that Paul can be correct in an email and still make me smile. 
The smile was the 1000x growth in internet traffic in a year.

Paul is right, this is a business case.  Since most people in the 
thread already make great points, I wont rehash them.  I think this 
is a standard peering argument that you could argue going back to 
1999 ISPcon panel that Bill Norton hosted.  There it was UUNET with 
ratios and settlement.  I will make the comment that I have a lot of 
respect for the AOL guys and Im sure there are some considerations 
that we are all not privy too.  To bolster their argument though, 
unlike uunet had at the time (or now) they do have caching servers, 
so that helps their argument of ratio consideration.

As for the business point, I always felt that peering was no place to 
make the money, which was not substantial anyhow, and likely short 
sighted.  The reason is, once you agree to that dirty word 
settlement, someone is likely to turn around and hit you up with it. 
Since you now have
"unclean" hands, it's hard for you to argue against it.  You should 
built a better backbone and use that and whatever model you have to 
out-compete your competition.  During these times I think it makes 
more sense to enhance the internet such that new technologies and 
uses can arise thereby driving business for us all.   As Paul 
mentioned, peering enhances the experience for users, but most apps 
dont need them today, and you need to justify a business model.

If one follows what happened in the computer world, we had a huge 
rapid growth in mips which no one could see a use for.  Then the GUI 
came about and ever larger apps.  The GUI enhanced the experience (no 
unix flames please).

Could we not then say that an enhanced internet "backbone" might 
create the matrix for new apps or technology not able to thrive 
today?  I am sure not many of us predicted the user to user traffic a 
few years ago.  Eyeballs to eyeballs traffic (peer to peer 
networking) just did not exist, but as DSL was widely deployed apps 
emerged to help fill the pipes.

Im sure a lot of eyeball networks were happy they did some good 
private peering connections to handle the initial traffic.

My 2cents.
