You also have to include variables such as cost of > the circuit(s) at a given data rate. True, but this even further complicates the optimization. You could equally consider multiple upstream provider transit costs. I was trying to keep it simple. I was simplifying based on the fact that most large providers own or lease their own backbones, and don't directly pay per bit on their own network. -Joel
