Abstract (in Japanese) (See Japanese page) 
(in English) When information systems are consolidated in a large data center, a huge amount of energy is consumed for transferring massive amounts of data to the data center through a wide area network. Our approach is to reduce the network power consumption by distributing servers capable of reducing or localizing traffic across the network. In this paper, we develop the models of applications, their traffic and a network system for transferring the traffic. We also introduce the models of router’s and server’s energy consumption, and formulate the power consumption caused by the traffic. Then, we evaluate the power consumption reduction as a result of traffic reduction by the distributed servers. Numerical evaluation results show that the whole power consumption reduces by about 20 percent when the more servers are added to the network; it increases due to the server power consumption when a lot of servers are added to the network.
