This is a very convoluted way of backing into the ole packet-switched
vs. circuit switched decision.

I don't follow. 
While ROADMs can be thought of as circuit-switchers,
the number of concurrent clients and switching latency put ROADMs on a different operational level than packet switchers, right?

Cheers,
