A session control apparatus, a session control method, and a session control program may maintain a quality of input data output to a processing module. The processing module has a defined condition regarding a quality of the input data. The session control apparatus includes an extraction unit, a selection unit, and a switching unit. The extraction unit extracts a plurality of candidates of devices. The selection unit selects at least one device from the plurality of candidates of devices. The switching unit switches the device that outputs the input data to the processing module to the at least one device selected by the selection unit. Each of the plurality of candidates of devices outputs input data satisfying the condition.
