Resumo


O crescimento explosivo do tráfego no backbone da Internet reflete o avanço nas tecnologias que possibilitam a popularização de aplicativos de rede de alta largura de banda e baixa latência. Contudo, o crescimento do tráfego e a capacidade da rede raramente se mostram compatíveis. Neste sentido, a tecnologia de Multiplexação por Divisão Espacial em Redes Ópticas Elásticas tem se mostrado bastante promissora devido às suas propriedades de ampliação da capacidade e ajuste de requisições. Este artigo propõe um algoritmo de roteamento e alocação de modulação, espectro e núcleo para as SDM-EON, com enfoque na redução da taxa de bloqueio de requisições via estratégias de redução de crosstalk médio e fragmentação. Os resultados obtidos demonstram a alta eficiência do algoritmo proposto no estabelecimento de conexões em comparação com algoritmos semelhantes na literatura.
