I agree with you 100%. Working at a nordic european operator being present at LINX, AMSIX and all the northern europe exchanges my reasoning is this: With IXes you buy one highspeed interface and get lots of peers and you can peer with people you might only exchange a few megabit/s with. Buying loads and loads of OC3s, T3s, OC12 to peer with and purchasing fiber patching to interconnect these just doesnt make sense when you can buy a GE or 10GE interface and get tens or hundreds of peers on that single interface without re-patching or establishing any new fiber connections. We have a very liberal peering policy which makes peering a pure operational decision, being handled by the line organisation. Each peering takes approx 5-10 minutes of someones time and that's it. No meetings of peering coordinators or alike, so those people are freed up to do better things. In a lot of the european exchanges all graphs of all ports on the IX is available to you as a member (or even publically available). If someone runs their port full, you probably know about it. Playing the peering game and trying to increase cost for someone else means you increase your own cost as well. Is that worth it? You have to be pretty big to justify it... -- Mikael Abrahamsson email: swmike@swm.pp.se
