So what is the replacement for IGP metric if they are useless?
You mentioned as well other protocols, will be great to know more about
these protocols.
It isn't necessarily protocols any more. It has more to do with how
calculations are made. They are starting to be made in centrally
controlled distributed fashion (if that makes sense). Look at min/max
linear optimizations as a start where individual nodes make flow
decisions based upon capacity available and bandwidth available not only
locally, but on the path(s) towards the destination. And the
calculations may be made on a per flow or flow batch mechanism.
Shortest path may no longer win, but the path established locally based
upon global parameters provided by neighbors as well as a central authority.
