Physically-diverse routing in heterogeneous optical networks
Systems and methods are described that provide a two-step, physically-diverse optical routing. A diverse routing is formulated using Integer Linear Programming (ILP) to find feasible routes having a minimum estimated cost, and post-processing the feasible routes on an auxiliary cost graph to optimize regenerator and terminal Optical Transponder (OT) placement and wavelength assignment.
