Abstract
Methods and systems for optical path computation based on a reachability matrix may rely on matrix multiplication to determine a number and respective network locations of regenerators for establishing an end-to-end reachable path in an optical network between a source node and a destination node. The reachability matrix may specify directly reachable optical paths between nodes in the optical network.
