Abstract (in Japanese) (See Japanese page) 
(in English) We have proposed a VNT (virtual network topology) reconfiguration method with traffic matrix estimation considerations. In this method, by dividing the whole VNT transition sequence into multiple transitions, estimation errors are calibrated at each stage by using network state information of prior stages. However, when some of traffics suddenly change, this method cannot accurately estimate the traffic matrix, because this method uses also network state information before the sudden change of traffics. Therefore, in this paper, we propose an estimation method which can estimate accurately the traffic matrix even in the case of sudden change of traffic. In our proposed method, we eliminate the information of the traffics changing suddenly from the network state information of prior stages. And then, by using the information after the elimination, we can estimate the traffic matrix accurately even in the case of sudden change of traffic. In this paper, we simulate our estimation method and verify that our estimation method can accurately estimate the traffic matrix even in the case of sudden change of traffic.
