Abstract: Elastic optical networks (EON) allow great flexibility through finer spectrum allocation granularity when compared to traditional WDM solutions. Their improved spectrum efficiency makes them a promising solution for next-generation backbone and metropolitan networks. Distant connections in elastic optical networks that are routed through multiple hops suffer from increased bandwidth blocking probability (BBP), in contrast to easier formulation of more direct connections. Traditional BBP as a metric fails to capture this phenomenon. In this work, a normalization of BP to the connection’s hop distance is proposed and a novel low complexity algorithm is presented that takes this new metric into consideration. Simulation results show that the proposed scheme improves network performance and fairness with no deterioration of BBP, when compared to the FirstFit RSA algorithm.
