The present invention performs efficient data transfer between devices. In particular, the present invention can reduce processing loads and power consumption of a response device 2 and increase overall throughput. When a request device 1 issues a direct transfer request to directly transfer data to or from a data storage unit 24 included in the response device 2, the response device 2 performs control so that data is directly transferred between a communication unit 23 and the data storage unit 24. The request device 1 is allowed to transparently and directly access the data storage unit 24 included in the response device 2 via the communication unit 24 between the request device 1 and the response device 2.
