Paper Abstract

Based on the P-cycles method and Hamiltonian cycle protection method, we propose a new resource-based cycle protection method for mesh WDM optical network, which is called RP-cycles method. And a heuristic algorithm of RP-cycles method is given. The method has many advantages such as simple configuration, independent of traffic model and having physical length limitation of cycles. Network simulations show that RP-cycles method has high capacity efficiency and short recovery time. So it is a new kind of practical optical network protection method for link fault.
