针对IP(互联网协议) over WDM(波分复用)网络的节能保护问题, 综合考虑业务持续时间和利用混合能源供能等因素, 提出了一种HTAGSPP(业务持续时间感知的绿色共享通路保护)算法, 鼓励选择业务持续时间内需要额外消耗传统能源最少的路径建立连接。仿真结果表明, 与传统节能共享保护算法相比, HTAGSPP算法消耗的传统能源更少且可使用更多的可再生能源, 在保持较低阻塞率的同时, 降低了业务平均传统能耗和二氧化碳排放量。

In order to solve the issue of energy-saving protection in IP over WDM networks, a Hold-Time-Aware Green Shared Path Protection (HTAGSPP) algorithm is proposed. The algorithm also considers the issues of holding-time of traffic and use of renewable energy. It encourages choosing the path with the least additional traditional energy consumption during the holding-time of traffic. The simulation results show that our proposed algorithm can not only maintain a low blocking probability and use renewable energy effectively, but also reduce traditional energy consumption and carbon emissions by using more renewable energy, when comparing with other traditional energy-saving shared path protection algorithms.
