Hi Bill, Just making sure that i get your point:
Youre saying that the probability of packet drop at peering points would roughly match that at the edge. Is it? I thought that most core switches have minimal buffering and really do cut-through forwarding. The idea is that the traffic that they receive is already shaped by the upstream routers.
