Link planning for multidomain optical networks using genetic algorithm

In this paper we propose a method to analyze and plan the allocation of gateway nodes in multidomain optical networks. The method is based on a genetic algorithm (GA), which determines the nodes with more resources to decrease the intra and interdomain blocking probabilities. The performance of the GA is compared with a network topology consisting of three domains in which the gateway nodes were selected by geographical reasons. The results of computer simulations show that for the optical-network multidomain topology analyzed the proposed method selects the most appropriate gateway nodes to improve the network performance.
