Abstract

In order to guarantee both the survivability of optical network and Quality of Service（QoS）

we introduce a crosstalk-evaluated approach by considering the inter-core spectrum status when establishing connection requests in Spatial Division Multiplexing Elastic Optical Networks（SDM-EONs） with Multicore Fiber（MCF）. Considering the survivability of optical networks and the crosstalk-evaluated approach

a new crosstalk-aware dedicated protection approach based on service bandwidth classification and the corresponding algorithm are proposed in SDM-EONs. For comparison

we also introduce three other traditional dedicated protection algorithms in SDM-EONs. Simulation results show that the proposed algorithm achieves lower blocking probability and doesn’t dramatically increase average crosstalk compared to three other traditional dedicated protection algorithms in SDM-EONs.
