PROBLEM TO BE SOLVED: To store a large amount of data without causing incomplete collection of data.SOLUTION: When packet storage devices 5a, 5b and 5c are in a state capable of performing storage processing of packets in a storage 37, the packet storage device 5a, 5b and 5c transmit packet transmission request to packet transfer devices 4a, 4b and 4c. When a packet is received from the packet transfer device 4a, 4b or 4c, if a tag inserted in the packet does not match the tag assigned to the packet storage device 5a, 5b or 5c, the packet storage device 5a, 5b or 5c returns the packet to the packet transfer device 4a, 4b or 4c, and if the inserted tag matches the tag assigned to the packet storage device 5a, 5b or 5c, the packet storage device 5a, 5b or 5c deletes the tag inserted in the packet and stores the tag-deleted packet in the storage 37. |
