PROBLEM TO BE SOLVED: To provide means for transmitting processing object data in high speed without decreasing reliability in a system to monitor and inspect communication on a network.SOLUTION: A monitoring subsystem 200 includes a plurality of processing units 210-240 that sequentially perform processing for communication logs, and performs processing while sequentially sending the communication logs from the headmost processing unit 210 to the subsequent processing units 220, 230 and 240. The last processing unit 240 notifies the first processing unit 210 that it has received communication logs. The first processing unit 210 re-transmits, to the subsequent processing units 220, 230 and 240, a communication log about which the first processing unit cannot confirm that it has arrived at the last processing unit 240 from notice from the last processing unit 240 among the communication logs processed by the first processing unit. |
