TRANSMISSION PACKET ANALYSIS SYSTEM, TRANSMISSION PACKET ANALYSIS DEVICE AND TRANSMISSION PACKET ANALYSIS PROGRAM

摘要

PROBLEM TO BE SOLVED: To analyze only transmission packets from among transmission packets and reception packets.SOLUTION: A switching device 130 receives a transmission packet 101 and a reception packet 102 communicated between a client device 110 connected to a local area network 119 and a server device 120 connected to Internet 129 and relays the received transmission packet 101 and the received reception packet 102 to a transmission destination. The switching device 130 outputs only the transmission packet 101 to a transmission packet analysis device 200. The transmission packet analysis device 200 acquires the transmission packet 101 output from the switching device 130 and analyzes the acquired transmission packet 101.
