PROBLEM TO BE SOLVED: To enable accurate packet replay.SOLUTION: A packet replay device 101 executes: analysis processing of acquiring a set of capture packets that is a duplication of a series of packets transmitted/received in a network from a packet collection device, collating attribute information on a protocol and communication layer included in each capture packet with each rule 407 in a storage device 106, identifying relation corresponding to the set of capture packets, and storing information on an execution condition corresponding to a condition of the relation in the storage device 106 while associating the information on the execution condition with the capture packet attribute information; and response processing of collating attribute information on a protocol and communication layer included in a packet transmitted/received by the packet replay device 101 as a node in the network with capture packet attribute information stored in the storage device 106, identifying information on an execution condition corresponding to a capture packet whose attribute information agrees with that of the transmitted/received packet, and executing packet replay according to the execution condition. |
