Reachability matrices spanning multiple domains in an optical network

A computer-readable device storing instructions, that when executed by a processing device, cause the processing device to provide routes through heterogeneous subsystems in an optical network by performing operations comprising:

• generating a reachability matrix based on subnetwork information associated with the heterogeneous subsystems, the reachability matrix comprising a list of reachable paths in the subnetwork information, the heterogeneous subsystems being associated with different vendors;
• generating a topology associated with the optical network using the reachability matrix;
• determining a shortest path through the optical network using the reachability matrix and a cost model graph;
• and
• providing heterogeneous subsystems associated with the shortest path, regeneration locations associated with the shortest path, wavelengths associated with the shortest path, the topology, and the shortest path.
