中文摘要：
针对带宽预留型业务提出了一种业务持续时间感知的绿色疏导算法,通过计算不同疏导策略的传输能耗,为业务选择最小能耗疏导策略;为进一步减小网络传输能耗,设计一种灵活触发光路合并操作的机制,该机制能根据光网络中不同光路的拆除时刻在业务传输前确定光路的合并时刻,减少了路由器端口和光收发器数目的使用,增加了光路带宽利用率.仿真结果表明,提出的时间感知绿色疏导算法能有效降低网络传输能耗.
英文摘要：
A green grooming algorithm, called as time-aware green grooming （TAGG） algorithm, is pro- posed for scheduled traffic requests. By comparing the transmission energy consumption for different traf- fic grooming strategies, the most energy-efficient traffic grooming strategy is selected in TAGG algorithm for traffic requests. Moreover, in order to further reduce the transmission energy consumption, a scheme is put forward to trigger the operation of merging light-paths. According to the moment of tearing down light-paths, the scheme can determine the moment of merging light-paths for traffic requests, which can reduce the number of required router ports and transceivers, and improve the wavelength bandwidth utili- zation. Simulation shows that the proposed TAGG algorithm can reduce transmission energy consumption effectively.
