Abstract
A network switch includes a field programmable gate array (FPGA) and a processor. The FPGA is configured to transfer a processing target packet to a transfer destination, based on transfer definition information, and to transfer a copy of the processing target packet to the processor. The processor is configured to delete an entry of the transfer definition information based on a transfer record information, and to update the transfer record information based on the copy of the processing target packet.
