Algoritmo de Roteamento para Otimização de Desempenho de uma Rede Óptica Elástica

Basically, when considering dynamic traffic and topologies with a high number of nodes, the Dijkstra algorithm is used and its cost function is modified in order to optimize the performance of optical networks. In this context, the contribution of this paper is to adapt a routing algorithm available in the wavelength division multiplexing optical networks for the scenario of elastic optical networks and to investigate its performance considering some routing algorithms. Aspects of the physical layer are considered, such as gains and losses along the devices, in addition to the amplified spontaneous emission noise generated in optical amplifiers.
