Crosstalk-sensitive RCSA with dedicated path protection in spatial division multiplexing elastic optical networks

Abstract

In this paper, we propose a novel routing, core, and spectrum assignment (RCSA) algorithm based on inter-core spectrum crosstalk measurement with dedicated path protection (RCSA-IC-SCM). We also introuduce two other RCSA algorithms with the no inter-core spectrum crosstalk measurement (RCSA-noIC-SCM) and traditional inter-core spectrum crosstalk measurement (RCSA-TIC-SCM) for comparison. Compared with other traditional RCSA algorithms, simulation results demonstrate that our proposed RCSA-IC-SCM algorithm achieves a better performance in terms of average inter-core crosstalk, blocking probability, and spectrum occupation ratio in spatial division multiplexing elastic optical networks (SDM-EONs).
