In order to realize eco societies, we have to reduce the total electrical power con- sumption in information systems. We classify network applications to transaction and communication based applications. While CPU resources of servers are mainly consumed in the transaction based ones, a large volume of data is transmitted by a server to a client in the communication based ones like le transfer protocol (FTP). We discuss a power consumption model for a communication-based applica- tions, which depends on the total transmission rate and number of clients where the server concurrently transmits les. A client has to select a server in a set of possible servers, each of which holds a le, so that the power consumption of the server is reduced. We discuss a pair of algorithms PCB (power consumption-based) and TRB (transmission rate-based) to select a server.
