| 摘要 | A path control system according to the present invention includes: a network including a communication device that communicates via a wireless link using adaptive modulation; and a path control device (201) that obtains bandwidth probability that corresponds to a bandwidth and that indicates a stability of the bandwidth with respect to the wireless link, preferentially sets a communication path whose bandwidth probability is higher than a predetermined threshold to the network, and prepares an alternate path for a communication path whose bandwidth probability is lower than the predetermined threshold. | ||

| 主权项 | 1. A path control device comprising: a bandwidth predictor that obtains bandwidth probability that corresponds to a bandwidth and that indicates a stability of the bandwidth with respect to a wireless link using adaptive modulation in a network including a communication device that communicates via the wireless link; and a path controller that preferentially sets a communication path whose bandwidth probability is higher than a predetermined threshold to the network and prepares an alternate path for a communication path whose bandwidth probability is lower than the predetermined threshold. | ||
