In these situations, I find it helps to mentally implement structural separation. So you have level3-Transit and Level3-CDN as separate companies. Netflix pays Level3-CDN to make content available locally in many cities. It is up to the ISP to find the most efficient way to connect to the Level3-CDN node(s). As a CDN, does Level3 offer free peering with ISPs who only have to pay for ports in a big switch ? ? Similarly, if there were Comcast-Transit and Comcast-ISP, and I purchase transit from Comcast-Transit, does it offer good connectivity around the world, or is it just a shell company that serves the Comcast-ISP ?
