| Abstract(in English) | According to the increasing power consumption of network equipment, a demand for reducing the power consumption of network routers exists. We suggest a power saving method by controlling the performance of the router to a suitable amount by referring the amount of received network traffic. The assignment of our method is to take balance between preventing the lack of quality of service and improving the efficiency of power saving. In this study, we have evaluated two algorithms by using real measured traffic. One algorithm is the long term fluctuation algorithm, which predicts the suitable performance by measured traffic over a past month. The other algorithm is the short term fluctuation feedback algorithm, which enables a real-time performance prediction according to the parameters measured inside the router, such as the amount of packets held inside the buffer of the router. As a result of the evaluation, a router adopting the short term fluctuation feedback algorithm was successful in reducing 33% more forwarding performance compared to a router adopting the burst detecting algorithm. We also evaluated the effect of the delay time of the forwarding performance to actually change since the suitable performance is detected, and met a conclusion that the delay time effects over the drop rate and the delay time of the packets been forwarded by the router. |
