Multicast protection problem on elastic optical networks using segment-base protection

Abstract

In this paper, the multicast protection problem on elastic optical networks (EONs) for the single link-failure case is considered. Two segment-based protection algorithms are proposed to solve this problem, they are Low Spectrum First Segmented Protection Algorithm (LSF-SPA) and K-Tree Segmented Protection Algorithm (KT-SPA). The simulation results for static multicast requests show that the blocking ratio and resource utilization ratio of KT-SPA and LSF-SPA are better than the other conventional methods. The blocking ratio of KT-SPA is better than LSF-SPA.
