Abstract: Network switching arrangements including: setting an operation mode of a target switching block to a operation mode that is different from an operation mode of a first switching block while the first switching block is handling a switching process, the target switching block being one switching block selected from second switching blocks; performing a switchover process including starting the switching process using the target switching block instead of the first switching block, after completion of setting the operation mode of the target switching block; and copying the switching information held by the first switching block to the target switching block, prior to starting the switching process using the target switching block, after completion of setting the operation mode of the target switching block.

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.
