Abstract

A history management unit within a discard determination unit manages transmission and reception packets related to a resource to be protected for each of users, and records communication history information for users high in use frequency through stateful measurement. A priority determination unit determines the priority of a communication on a per received packet basis on the basis of communication history information. A load determination unit determines a load level of the resource to be protected, and combines the load level with the priority of the communication determined on the per received packet basis. A discard rate determination unit and a packet discard unit implement forwarding processing, determine the priority of the communication on the per user basis, and discard communications low in the priority at a high ratio.
