Yes.

I don't know.

Yes, probably better than constand retraining ML models.

Use probabability to know which next-hops to use in a FIB entry. Start with a 
static topology baseline and then prune paths based on probablility of failure 
(typical links going up and down, nodes not reliable, etc).

This is very high-level. And this is NOT SDN. All predications are done local 
to a router. Just like my phone and car do it for other types of 
applications/use-cases.
