摘　　要：分析了核心光网络的能耗结构和能够减少光网络能耗的基本方法,即光旁路和业务量疏导方法。以一个简单的网络拓扑为例,分析了多线速光网中各设备的能耗情况,并通过数据仿真进行了有无旁路状态下总能耗的对比、单线速和多线速业务量疏导情况下的总能耗对比,数值结果说明了这些方法的有效性。The paper analyses the two basic methods of reducing the optical network energy consumption： op- tical bypass and traffic grooming. A simple network topology is used as an example to analyze the power consumption of devices in optical networks. Numerical results are given to demonstrate the difference of the total power consumption between with and without optical bypass, single-line-speed and multiple-line-speed traffic grooming, which verifies the effect of optical bypass and multiple-line-speed traffic grooming.
