An Effective Routing Algorithm for Dynamic Shared Path Protection in ASON

Abstract:

This paper proposed an efficient online algorithm, called JPS-SR, for shared path protection under dynamic traffic conditions in GMPLS. The algorithm was improved by introducing the set v_e, parameter α and ε, which reduced average hops of paths, and increased utilization of resources. The performance of JPS-SR was evaluated via simulation with FIR based on SPS (SPS-FIR) on a typical network (NSFNet). The simulation results show that JPS-SR can optimize the resource utilization and blocking probability.
