摘要
The fundamental of the dual link failures protection with P-cycles in mesh optical networks was introduced. The configuration strategy of the protection cycles with P-cycles in networks with at least 3 degrees was then discussed. Furthermore, a heuristic algorithm based on the working resource distribution and the straddling links efficiency was proposed. And the proposed algorithm was simulated in COST239 network under static traffic model on OPNET simulation platform. The results show that the proposed algorithm has shorter restoration time and lower capacity redundancy.
