It can also be argued that at some point, the speed capabilities of the core router scheme will not be able to keep up with currently technology.
Yawn. What do you think the speed capabilities of "core router scheme" are? You know, some very fast routers are rumored to ship this year.
It's my opinion that at some point a 'routed' core will no longer be feasible, and it will be switched -- using what mechanism, I don't know (ATM? MPLS?).
ATM, MPLS (or whatever idiotic virtual circuit scheme there is) can not increase switching or routing capacity of boxes, period. These only serve to screw up dynamic adaptive routing, forcing carriers to rely on wasteful dual-ring SONET redundancy instead (and it still doesn't protect from a switch crashing every few minutes). --vadim
