Abstract (in Japanese) (See Japanese page) 
(in English) With the growing energy consumption of the Internet, power saving technology in the Internet is becoming vital issue for economic and global environment. Therefore, we have focused on the energy consumption of network's edge, and proposed a method which keeps the interface in active mode for an extra period after all packets are flushed out from the buffer in order to reduce the number of mode switchings. The numerical results show how the duration of the extra active period degrades the energy saving performance while successfully reducing the number of mode changes. However, much energy is consumed in the network's core because deployed ethernet switches always work with the full throttle regardless of the traffic condition. Such switches can use the link aggregation based on the IEEE 802.3ad, thus, in this study, we propose the power saving scheme which controls the number of physical links between two switches according with the changing traffic condition. From simulation studies, we show that the proposed scheme can achieve the effective energy saving in response to the changing traffic condition.
