A first wire and a second wire are each shorter than a third wire.

Abstract: This invention satisfactorily prevents another person from accessing a terminal that is in use, without reducing a bandwidth allocated to a dedicated peer-to-peer path for the terminal that is in use. A controller controls processing of receiving a request from a first terminal for connection to a second terminal, and processing of transmitting, when the second terminal is in use, a notification that connection cannot be established to the first terminal. For example, the controller recognizes that the second terminal is in use on the basis of connection information stored in a storage unit or on the basis of connection information received from another network device that transmits the request for connection to the second terminal transmitted from the first terminal.
