Re: Optical Crossconnects and IP

When circuits aren't overloaded, traffic engineering yields zero benefit.

Slightly disingenuous - Yes, TE yields zero benefit in terms of getting more 'efficient' use of bandwidth resource (if you have bandwidth that's idle when the network is used inefficiently, who cares) and in terms of traffic prioritization (if it all gets through without queuing delay, who cares). But the apostles of TE claim more miracles than the above two for their religion (all the funky stuff from encapsulation for instance). Now whether one doubts these miracles too is another matter... -- Alex Bligh VP Core Network, Concentric Network Corporation (formerly GX Networks, Xara Networks)
