Algorithm for Protection of Space Division Multiplexing Elastic Optical Networks

In recent years, elastic optical networks have emerged as a solution for dealing with the diversity of the bandwidth demands of network applications. The use of only two multiplexing dimensions has limited the network capacity. To ameliorate this problem, a third dimension has been added in space-division multiplexing (SDM). As transmission rates increase so does the need for protection against network failures. Among the protection schemes, those protecting paths are of great interest due to their end-to-end solutions. This paper introduces a novel algorithm based on p-cycle to provide failure-independent path protection in elastic optical networks with SDM.
