Abstract
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 unit which calculates a stability level indicating a probability that a bandwidth is available in a wireless link using adaptive modulation, a utilization rate calculation unit which calculates a utilization rate of a bandwidth used by traffic to be accommodated, an allocation unit which allocates, to the traffic, a link bandwidth of the stability level corresponding to the utilization rate of the traffic, and a path control unit 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.
