Resumo

As redes ópticas elásticas com multiplexação por divisão de espacial (SDM-EONs) são apontadas como tecnologia para prover comunicação no núcleo da Internet. Este artigo propõe o Algoritmo Ciente de Crosstalk para Alocação de Núcleo e Espectro (ACiNE) em SDM-EONs. O ACiNE escolhe faixas espectrais com menor valor de crosstalk e de forma balanceada, obtendo melhor eficiência quando comparado a outros trabalhos da literatura. Neste contexto, o ACiNE obteve ganhos de pelo menos 45,62% em termos de probabilidade de bloqueio de circuito, 37,95% em termos de razão de dados bloqueados e 7,19% de eficiência energética. Além disso, o ACiNE possui menor tempo de execução quando comparado a outro algoritmo ciente de crosstalk.
