You need to update your list BAD. We are connected to all but one of your NAPs listed. We wanted to be at Sprint-NAP 4 months ago, but they did not have the gigaswitch port, or the physical space for our hardware. Please do not put information about other provider up without checking it out first.
I guess everyone can see why CERFNET stopped updating their web page about exchange point connections. Sorry, I missed your pacbell nap connection. It appeared down when I pinged it earlier, but now it appears up. I'll update my spreadsheet. I figure people wouldn't be shy about correcting me. I've also noticed they haven't been as forthcoming when I listed a connection that isn't 100% operational. Actually, I'm doing well so far. The correction responses break down like this, so far. 2 AS number corrections 1 non-operational connection listed as operational 6 operational connection not listed (4 involving CIX/PAIX) So far the most common response has concerned the CIX =/= PAIX problem. When I set up my spreadsheet, there was only the 149.20 CIX network, and that's what the spreadsheet is based on. The CIX router at the PAIX is also connected to the PAIX FDDI ring. After some mail last night, I looked at adding the PAIX side; but it quickly got very complicated. There are some people on the PAIX side which are peered with the CIX router, and some that aren't. But I can't tell just by pinging the network address. Then I started getting mail asking why I hadn't included a variety of the other 200+ exchange points that claim to be operating world-wide. So the question becomes, if I do this again, how do I choose the six (because I have limited resources, and no government grant money, and can't get advertising dollars publishing an ISP directory) major, biggest, most important,or just plain interesting exchange points in the world to put the the spreadsheet. Or is the entire thing irrelevant, because everyone is moving to private bilateral connections. And the important thing is how many providers does someone peer, not how many exchange points they're connected to. For the price of one Sprint-NAP connection, I can get several connections to Canada. And we have a lot more customers in Canada than at the Sprint-NAP. We already peer with everyone at the Sprint-NAP, or been turned down by them elsewhere. So one more exchange point doesn't buy much. -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation

By using publically available traffic stats like: PEAK EXCHANGE 750 Mbps http://www.mfsdatanet.com:80/MAE/west.giga.overlay.html 750 Mbps http://www.mfsdatanet.com:80/MAE/east.giga.overlay.html 180 Mbps http://www.pacbell.com/products/business/fastrak/networking/nap/stats/graph_... 110 Mbps? http://nap.aads.net/~nap-stat/AADS.NAP/atm/970325.html (This looks broken) Interesting note: MAE-WEST is now starting to handle more traffic than MAE-EAST. If my memory serves me correct, early last year MAE-WEST was doing something like 350 Mbps and MAE-EAST was doing 550 Mbps.

Lacking the ability to find out who peers with who (except by looking through the RADB :) and the ability to know private flow data (except for ours) a rough metric to answer this is the amount of daily traffic handled by an exchange (as shown above) and the number of routes seen by the routing arbiter there (from http://www.merit.edu/ipma/routing_table/). Based on the continuing growth in both members and traffic of the exchange points, I'd say economics drives exchange points.

The SprintNAP is a much less congested place than MAE-East (though most providers also have less capacity out of it [besides Sprintlink, GSL, ICM, etc...])... Avi
