Routing, spectrum and core assignment algorithms for protection of space division multiplexing elastic optical networks

Abstract

Protection is a key issue in optical networks, mainly in spacial division multiplexing (SDM) elastic optical networks (EONs) as these handle the increasing amount of heterogeneous Internet traffic. In this paper, we address protection in SDM-EONs including inter-core crosstalk. We introduce three algorithms, designed to provide 100% protection from single failures. Extensive simulation is used to show that the proposed algorithms prevents the formation of network bottlenecks, thus maintaining the protection of the connections.
