  • This paper proposes a Path Based-Optimized Shared-Protection algorithm for Multicast sessions (PB-OSPM) against single link failure in WDM mesh networks. Based on the Optimal Path-Pair-based Shared Disjoint Paths (OPP-SDP) algorithm, PB-OSPM introduces wavelength usage matrix and wavelength reservation matrix to record the detailed usage of wavelengths reserved in the past so that the sharing of reserved wavelengths between protection paths of different multicast sessions can be enabled if the paths are not going to act at the same time. Study uses the topology of European Optical Network (EON) to simulate the network redundancy with an increasing network load and the blocking probability under various conditions of wavelength resources and dynamic network loads. The simulation results demonstrate the superiority of PB-OSPM over OPP-SDP and prove sharing wavelengths between different multicast sessions to be an effective way to improve wavelength usage.
