I think the point of TE is to avoid overbooking in the first place, and also calculate a suitably assured protection path.

May be so, but at some point every business will be accountable to operating cost. This is the hallmark of a mature sector in a commodity market, in fact. > PPS Pluris core technology allows to treat traffic as a liquid - unlike simple > IP routing it works by splitting aggregated streams, which can be sent > along different paths. Not by hashing flows I hope. Otherwise, I suspect that non-Newtonian CFD per macroflow can't possibly be a time-complexity win over the "simple" MCF optimization problem... :P Regards, Andrew Bender thrupoint.net
