In order to realize eco societies, we have to reduce the total electrical power consumption 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 file transfer protocol (FTP). We discuss a power consumption model for a communication-based applications, which depends on the total transmission rate and number of clients where the server concurrently transmits files. A client has to select a server in a set of possible servers, each of which holds a file, 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.
