Spectrum Overlap and Traffic Grooming in P-Cycle Algorithm Protected SDM Optical Networks

The Space division multiplexing (SDM) in elastic optical networks brings new challenges for protection of networks since a lightpath can span multiple cores. Although previous studies have studied protection in SDM elastic optical networks (EON), no work has considered the joint use of p-cycle, traffic grooming and spectrum overlap for these networks. In this paper, we investigate the problem of protection in space division multiplexing elastic optical networks, generating primary paths and p-cycles. The proposed solution allows a more efficient use of network, keeping crosstalk acceptable. Results derived via simulation show that the proposed spectrum overlap, traffic grooming and FIPP p-cycle algorithm can keep the quality of transmission and yet decrease the blocking of connections.
