Abstract
A bandwidth control device includes: a management unit to subtract, when a first bandwidth control device (first device) or one or more second bandwidth control devices (second devices) allow a packet to pass, an amount of the passed packet from a permissible passage amount to be passed the first device; and a correction unit to correct the permissible passage amount of the first device or a threshold value of the first device based on a result of a comparison between a passage amount of packets passed the first device and passage amounts of packets passed the second devices, wherein the first device determines whether a packet is to be allowed to pass through or not based on a result of a comparison between the permissible passage amount and the threshold value and allows the packet to pass or discard the packet according to the determination result.
