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.
