And it has a settlement free peering policy - with a stated requirement that traffic exchanged be symmetrical.
Analysing the effects of vertical integration is often best done by running structural separation scenarios. Netflix does not give content to Comcast-transit, it gives it to Comcast-ISP, this is especially true of cases where a network cache server is installed inside Comcast-ISP network. If Comcast-ISP told Netflix to install cache servers at one location, and then Comcast-ISP uses Comcast-transit to distribute content to all the cities it serves, it should be Comcast-ISP paying Comcast-transit for that service. It could just as well have installed the netflix appliance in every major city and not have to purchase transit from Comcast-transit.
