  • System for routing and wavelength assignment in wavelength division multiplexing optical networks
    Patent number: 8693871
    Abstract: A method for routing and wavelength assignment (RWA) in an optical network with improved heuristics for reducing the computational times required for the RWA. The method minimizes the number of wavelengths by packing the lightpaths using a minimum number of bins in a bin packing problem. Computational efficiency is enhanced by using several novel methods to determine shortest paths and eliminate arcs in a graph that represents the network topology.
