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.

So, if the packet has made it past the first mile and has "entered" the core then chances are high that the packet will safely get across till the exit in the core.Hi Glen, I would expect congestion loss at enough peering points (center of the core) to put it in the same league as noisy cable at the edge.
