Abstract (in Japanese) (See Japanese page) 
(in English) Packet classification is to classify packets arriving a network equipment according to the classification policy. It is achieved by linear search that compares packets with rules in the rule list representing the classification policy one by one. Linear search has the problem that the larger the number of rules becomes, the processing latency is increasing. This latency can be reduced when a lot of packets are evaluated at the top of the rule list. Therefore, in this article, we introduce the optimization problem called optimal white list constructing, that minimizes the latency caused by packet classification preserving the classification policy. Besides, we prove that the decision version of this optimization problem is NP-hard by reducing from the decision problem, ONSET TRUTH TABLE MIN SOP. This fact suggests that we should develop a heuristic algorithm instead of an exact algorithm for optimal white list constructing and investigate what property implies this hard problem is solvable in polynomial time.
