摘要： 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.

摘要： It is an object of the present invention to achieve improvement of security by a whitelist function and improvement of network reliability by a network redundancy function at the same time. A packet relay device 100 includes packet reception units 200, a packet transfer unit 300, a S/W control unit 400, packet transmission units 500, and an input/output interface 600 and automatically generates a whitelist including an allowed communication rule. It is possible to select whether to perform communication control using the whitelist or to carry out data communication without using the whitelist for each data reception unit 200 that receives data.
