    摘要： To provide a path control device and a path control method which are capable of adaptively coping with changes in a network such as a change in traffic and a change in link quality. A path control device according to the present invention is a path control device 10 that sets a communication path using multiple radio links connecting multiple communication devices, the path control device including a link information management unit 11 that manages a first communication quality of each of the radio links; a traffic information management unit 12 that manages a state of traffic flowing through the radio links; and a path setting unit 13 that sets a path of a flow such that the first communication quality satisfies a second communication quality required by the flow flowing through the radio links, based on at least one of a change in the first communication quality and a change in the traffic state.
