Claim Text:
1. A packet transfer processing method comprising: an input destination switching step of selecting one of a plurality of common processing units, that perform processing common to first transfer processing for receiving a packet from a first network and transferring the packet to a second network and second transfer processing for receiving a packet from the second network and transferring the packet to the first network, to which the packets received from the first network and the second network are to be input; a common processing step of causing the plurality of common processing units to perform the processing common to the first transfer processing and the second transfer processing; an output destination switching step of outputting packets processed in the common processing step to a network of a transfer destination; an individual processing switching step of selecting which common processing unit is to be connected to at least one individual processing unit that performs at least one of first individual processing as part of the first transfer processing not executed by the plurality of common processing units and second individual processing as part of the second transfer processing not executed by the plurality of common processing units; and a control step of performing selection control in the input destination switching step, selection control in the individual processing switching step, and control of switching supply/shutoff of power to the plurality of common processing units.
