A Genetic Algorithm to Design Logical Topologies with Low Congestion in Reconfigurable WDM Networks

We present a novel genetic algorithm to design logical topologies for reconfigurable wavelength-routed optical networks. Not only does the algorithm determine which nodes should be connected by means of lightpaths with the aim of minimizing congestion, but it also solves the routing and wavelength assignment problem and routes the traffic in the logical topology. The algorithm is effective in terms of congestion achieving reductions of up to 80% when compared with previous works.
