Hi Mehmet,

Nothing to do with adjacencies. I'm honestly not sure why anyone plays the "I've got the most peers" game but that's a different conversation.

Unfortunately my age & the amount of time I've spent away from retail ISPs is showing here. What I'm looking for is where traffic is coming from. Wind the clock back a few years and a top talker list for many ISPs would have Google, Akamai, Facebook, etc.. You could say "hey my traffic is coming from these ASNs, here's who I need to talk to for bilats, or here's the exchange I need to peer at to pick up this traffic for free".

This is only a valid question for an ISP until they start getting deploying cache boxes in-network. What I'm seeing now from the notes coming back off-list (thanks x4 so far!) is:
  1. Many cache boxes are using local provider IP space. So I shouldn't have asked for ASNs.
  2. ISPs may be paying a transit provider differential rates for transit & cache access but it's all coming from the same ASN.
  3. Some ISPs don't have an easy way to judge what percentage of their traffic is being serviced by the caches as they're not running netflow on the internal routers.

The useful feedback I've had is that traffic is coming from (in alphabetical order):
  • Akamai
  • Amazon
  • Apple
  • Dropbox
  • Edgecast
  • Facebook
  • Fastly
  • Google
  • Limelight
  • Microsoft
  • Netflix

Hi Folks,

I'm trying to help out a customer in the Pacific understand what a developed market traffic profile looks like.

In particular I'm looking for a list of your top 20 ASNs by traffic volume. Big bonus if you can attach percentages to those ASNs.

If any of you can share any rough detail it would be much appreciated. Anything's fine - attributable, non-attributable, fallen off the back of a truck, apocryphal tales from a late night whisky session, whatever.
