Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, large file downloading requests on high-speed and huge computer networks are increasing rapidly.These requests are typically handled in the best-effort manner, which results in unstable completion time.We consider the model where a download request must be completed until its deadline given by a user and rejected if it cannot be satisfied in a bandwidth guaranteed network.To accept more requests, it is preferable that there are more ongoing requests with loose deadline in a network.In this paper, we propose a dynamic bandwidth assignment method to reduce the blocking probability, by introducing a new metric to consider the utility time and the usage of bandwidth.The proposed method gives higher priority to the request which have higher metric.Finally, simulation experiments show its exellent performance.
