Pre-configured prism (p-Prism) method against simultaneous dual-link failure in optical networks
Pre-configured prism (p-Prism) is proposed to handle dual-link failure, which uses less protection links than p-Cycle. Resources reservation strategy is proposed to flexibly reserve protection resources on p-Prism. Simulation results show that p-Prism has better performance than p-Cycle at both static and dynamic indexes.
