摘要： To provide a packet forwarding device which minimizes degradation in packet forwarding performance at the time of execution of filtering there is provided a technique in which a destination decision processing unit of a destination decision and filtering unit decides whether to execute filtering on the basis of at least one of an input interface, an input port number, an output interface, and an output port number of an input packet and a plurality of pieces of information constituting the header of the packet. A filtering unit executes filtering only for a packet for which execution of filtering is decided. The packet forwarding device with the destination decision and filtering unit need not execute filtering for all packets and can minimize degradation in packet forwarding performance caused by filtering.
