A new P-cycle algorithm was proposed to improve the protection success ratio for asymmetric traffics in mesh optical networks. The proposed algorithm was simulated in Pan-European COST239 network environment under asymmetric dynamic traffic model. The experiment shows that the proposed algorithm has lower capacity redundancy and higher utilization rate of configured resources than that of traditional P-cycle methods. The network performance can be significantly improved when this algorithm is implemented under single-link failure circumstances. The system behavior is analyzed under different traffic volumes, and the configuration strategy is also investigated for the heavy-load and light-loads network respectively.
