Abstract

The adoption of spatial division multiplexing in elastic optical networks has created new challenges for the allocation of optical resources. The inter-core crosstalk appears when the same optical frequency is used in adjacent cores. In this paper, the inter-core spectral distancing algorithm (ADEIN) is proposed. To avoid crosstalk, ADEIN balances the use of resources in order to prioritize certain groups of cores and spectral slices. The proposal achieved a minimal improvement in the bandwidth blocking probability of 47.01% compared to other algorithms in the literature. For the circuit blocking probability, the improvement was at least 44.64%.
