A Low Power Consumption Frequency Adaptation Mechanism Based on the Traffic and Implementation on NetFPGA

Both in academic and industrial research, building a green energy-saving network has become a hot topic. Combined with hardware division and adaptive algorithm, this paper proposes an adaptive frequency control mechanism based on traffic to reduce power consumption. By calculating real-time traffic, the network device can adjust its operating frequency. On the premise of maintaining network performance, this mechanism could reduce the power consumption significantly. Besides, the adaptive frequency mechanism has been verified and realized in the NetFPGA Reference Router. Experimental data show that under different ranges of traffic loads and without affect its performance, the Router embedded this mechanism can reduce power consumption by more than 20%.
