In short, the idea is that optical networks are wasteful and routers do a better job making more use of a network's capacity than ROADMs. Take the extra router hop (or 3 or 8) versus short-cutting it with an optical network because the silicon is so low-latency anyway that it hardly makes a difference now. Putting more GBs per second on fewer strands means saving a lot of money on infrastructure costs.
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, Etienne On Tue, May 2, 2023 at 4:29 PM Izaac <izaac@setec.org> wrote:
