Análise de Desempenho de Algoritmos de Roteamento e Alocação de Comprimentos de Onda em Redes WDM

— The performance of WDM networks are usually analized through the blocking probability of a given request. It is argued that alternative routes can have a significant impact on the blocking probability of a WDM network. In this work, we analize the impact of alternative routes in mesh and ring topologies. Results show that, contrary to our expectation, having alternative routes can have a negative impact in certain cases .
