针对波分复用光网络的节能保护问题,提出一种带有业务持续时间感知的共享保护算法.在权衡网络的阻塞率和节能效率时,综合考虑链路的业务持续时间、资源利用率及链路状态等因素,提出启发式算法对工作路径和备份路径进行联合优化选路,从而提供100%的单链路故障保护.仿真结果表明:与传统节能共享保护算法相比,所提算法在降低网络阻塞率的同时更有效地降低了网络能耗.
Aiming at energy-saving protection of WDM optical networks, this paper proposes a sharing protection algorithm with service-duration perception. When considering the blocking rate and energy-saving efficiency of the network, the link duration, resource utilization, Link status and other factors, a heuristic algorithm is proposed to jointly optimize the working path and the backup path to provide 100% single-link fault protection.The simulation results show that compared with the traditional energy-saving shared protection algorithm, the proposed algorithm Reduce the network congestion rate at the same time more effectively reduce the network energy consumption.
