Re: Long hops on international paths

So, the question is what is the cost/benefit to providers to configure/maintain routes (that include long MPLS tunnels) that tend to concentrate international connectivity at a relatively small number of routers?

the cost of mpls TE is pretty low: a couple of extra config lines per LSP. The benefit can be substantial in terms of having fine-grained control of how packets traverse a network, and allow optimisation of specific policy outcomes, e.g. cost / latency / throughput / pktloss / qos / etc. Nick
