    摘要： In a network configured using a wireless link in which a transmission rate fluctuates, accommodation efficiency of traffic is improved while communication quality of VBR traffic is maintained. A bandwidth control device includes a stability level calculation means which calculates a stability level indicating a probability that a bandwidth is available in a wireless link using adaptive modulation, a utilization rate calculation means which calculates a utilization rate of a bandwidth used by traffic to be accommodated, an allocation means which allocates, to the traffic, a link bandwidth of the stability level corresponding to the utilization rate of the traffic, and a path control means which sets a path for the traffic in the wireless network including a communication device that performs communication over the wireless link based on the allocated link bandwidth.

    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.
