On the international slide, I've seen a slide presentation from Deutche Telecom that said that half of all of its traffic stayed in country, which *I'd* label as "local". This is all WAG, tho. I'll argue that you can never measure this accurately from the network (how much traffic did you *not* count?, how much traffic was delivered on campus? is the site multihomed?), you have to measure it from the edge. To really test this you need sampling from the users, ala the Nielson method and knowledge of geography for IP addresses. Market opportunity anyone? -scott

I'd guestimate that local peering and stuff accounts for as much as 5 to 15% of our traffic.
Perhaps someone who is actually running a local exchange can report on how much traffic they are carrying that is now not being sent to a MAE-equivalent? I think that actual experience and hard data will surprise us all.

The problem there, as I at least alluded to in my previous posting is that, unless you already _have_ the local exchange, there's no was at the edge router level to log the "local" traffic vs the "remote" traffic -- you could only do it in a local exchange environment by virtue of the fact that theexchange existed in the first palce, to give the locals a place to exchange routing info.

You could use flow export data to see this, as long as you know which ASes you would have reached through the XP had it been there.. -Phil

Yup. If your router has the right image, and the horsepower. And after you go hand sift whois looking for those AS numbers... Didn't say it was impossible. Just a real PITA> Cheers, -- jra -- Jay R.
