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.
Aiming at bandwidth reservation service, a service grooming algorithm based on perceived service duration is proposed. The minimum energy consumption strategy is selected for the service by calculating the transmission energy consumption of different grooming strategies. To further reduce the energy consumption of network transmission, The mechanism of flexible triggering of optical path merging operation can determine the merging moment of the optical paths before the service is transmitted according to the removal timing of different optical paths in the optical network and reduce the use of the number of router ports and optical transceivers and increase the optical path bandwidth utilization rate. It shows that the proposed time-aware green grooming algorithm can effectively reduce the network transmission energy consumption.
