Abstract (in Japanese) (See Japanese page) 
(in English) Recently, as the amount of traffic through network grows, the necessity of sampling has been increasing for analyzing the traffic data rapidly. The sampling is classified into packet-based sampling and flow-based sampling. The former has an advantage that it is easy to be implemented and be used widely, but has a disadvantage that the obtained precision of flow statistics is bad. The latter has an advantage that it is superior to packet-based sampling for measuring the flow statistics. However, it has a disadvantage that there are no devices in which the flow-based sampling is implemented because it requires per-packet classification. In this paper, we propose the method which utilizes the wildcard mask of the access list in order to realize the flow-based sampling. Compared with a flow-based sampling by hashing, in case of that flows were not sampled so much, we confirmed that our proposed method was effective for actual network operation.
