面向能效优化的控制队列时延算法

CONTROLLING QUEUE DELAY ALGORITHM FOR ENERGY EFFICIENCY OPTIMISATION

针对一种具有严格时延约束的网络数据流量到达与离开的场景,分析其流量转发过程的能耗特性,提出一种面向能效优化的控制队列时延算法——eeCoDel(Energy Efficient CoDel)。该算法根据数据包时延约束,动态选取最大速率进行数据转发。进行仿真实验对比CoDel、DCQA以及eeCoDel算法的转发能耗。结果表明eeCoDel相比其他两种队列管理算法能够有效降低数据转发过程中的能耗,并且能够兼顾数据流的QoS要求。

We analysed energy consumption characteristics of the network data traffic with strict delay constraint in its traffic forwarding process aimed at its scenario of arrival and departure, and then proposed an energy efficiency optimisation-oriented controlling queue delay algorithm, namely eeCoDel. This algorithm dynamically selects maximum speed to forward data based on data packet delay constraint. A simulation has been conducted to compare the energy consumption of CoDel, DCQA and eeCoDel. Results indicated that eeCoDel algorithm, relative to other two queue management algorithms, can effectively reduce the energy consumption in data forwarding process, and meet the requirements of QoS at the same time.
