Anyone thought about eliminating large physical exchange points and replacing them with a more distributed architecture?
Multiple data centers interconnected over ATM in a single metro area run by indepdenant entities who are free to provide any level of service or value add they wish.
Thoughts?
It sounds alot like the multi-tiered proposal I put forth about 3 years ago to build local exchanges on top of frame networks in certain cities, then interconnect cities to regional exchanges, then interconnect the regional exchanges. That architecture takes advantage of traffic locality as well as providing a path out for non-local traffic. If the individual regional exchanges have a small enough number of participants, they are easier to manage, and should one participant have alot of traffic going to regional or inter-regional exchange, you simply install a PVC to there. There is some breakpoint for scaling however... I think it still would work pretty well on top of Frame, though it is aimed at the local/regional ISP rather than the nationals. Bob
