I would appreciate more detailed insights as to why you (and others) feel this way. It is not at all obvious to me. > For computing routes, we have been using distributed SPF on every node for > many years. True, but that algorithm is (and was) very well known and a fixed algorithm that would clearly solve the problem at the time. If we were in a similar situation, where we were ready to set an algorithm in concrete, I might well agree, but it’s quite clear that we are NOT at that point yet. We will need to experiment and modify algorithms, and as discussed, that’s easier with a centralized approach. > In fact, we may not need to run the exact algorithm on every node.

Insuring a globally consistent result without running the exact same algorithm on the exact same data will be quite a trick. Debugging distributed problems at scale is already a hard problem. Having different algorithms in different locations would add another order of magnitude in difficulty. No thank you.
