I can assure you the path from Akamai to Charter is not following that path, this is an asymmetrical path. We are helping USInternet provide cache fill for Akamai by announcing the prefix through commercial peering relationships we have. Along with cache fill comes some TCP Ack traffic depending on some people's routing policy. -- =============================================== David Farmer Email:farmer@umn.edu Networking & Telecommunication Services Office of Information Technology University of Minnesota 2218 University Ave SE Phone: 612-626-0815 Minneapolis, MN 55414-3029 Cell: 612-812-9952 =============================================== On Mar 21, 2013, at 21:11, Jeremy Lumby <jlumby@MNVOIP.COM> wrote:
I was a little interested in seeing which Akamai cluster would feed my Charter home internet connection if I decided to stream NCAA basketball. A quick packet capture revealed a very familiar IP address. However when I tracerouted to it, I was surprised to see it go through the University transit MICE, and then loop back on USinternet to get to the MICE Akamai cluster.
