Abstract

A combined routing and core-spectrum assignment (RCSA) scheme is proposed for spatial division multiplexing elastic optical networks (SDM-EONs). The improved algorithm will evaluate resource availability based on existing link status and select suitable core combination for transmission. The service requirements will be reasonably allocated spectrum resource depending on the assessment of the crosstalk effects between different cores and frequency spectrum availability. Simulation results show that the proposed algorithm can improve both the resource utilization and blocking probability compared with traditional algorithms.
