Paper Abstract

Space division multiplexing elastic optical networks (SDM-EONs) are advocated as a promising solution to cater to the significant increasing of network bandwidth demands. In this paper, a novel crosstalk-aware and flexible grouping routing, spectrum and core assignment (CaFG RSCA) algorithm based on mixed super-channel is proposed to suppress the spectrum fragments and improve the network performance in SDM-EONs. The algorithm focuses on the issues of spectrum fragmentation and allocation efficiency with consideration on the inter-core crosstalk in multi-core fiber (MCF). Simulation results confirm that the proposed algorithm gains effective reduction in spectrum fragments and performs better than other congeneric algorithms in terms of the service blocking probability and spectrum resource utilization.
