Abstract:
1. A communication medium determining apparatus which determines a communication medium in use for communication through a given communication path, said communication medium determining apparatus comprising: a communication performance obtaining unit configured to obtain (i) a value indicating a transmission speed in the given communication path when a device is active and (ii) a value indicating a transmission speed in the given communication path when the device is inactive, the device being a cause of decrease in transmission speed in a specific communication medium when the device is activated; and a communication medium determining unit configured to determine whether or not the communication through the given communication path is performed using the specific communication medium, based on (i) a speed decrease value indicating an amount of decrease in the transmission speed in the specific communication medium caused by activation of the device and (ii) a speed difference value which is a difference between the transmission speed obtained by said communication performance obtaining unit when the device is active and the transmission speed obtained when the device is inactive.
