Comparing OSNR based policies for an adaptive-alternative IA-RWA algorithm applied to all-optical networks

We propose two policies to select the route for an adaptive-alternative routing algorithm for all-optical networks. We use the NrPSR to find the Nr routes with lower cost for a given source-destination pair according to a cost function expanded in a power series (PSR) in which the coefficients are determined by a Particle Swarm Optimizer (PSO). The selected route to attend to the call request can be chosen among the Nr found routes depending on the adopted policy. In the first proposal, named NrPSR(OSNR JE), we select the route that presents the lower OSNR that attends the Quality of Transmiss...
