PROBLEM TO BE SOLVED: To identify a virtual router if the virtual router performing address conversion exists in an information processing system.SOLUTION: When a VM connected with the virtual switch through a plurality of interfaces is generated, a capture setting control unit 72 sets the data capture of the plurality of interfaces. Then, a capture data processing unit 73 receives capture data to register flow information into a flow information table 62. Then, a virtual router identification unit 74 compares IP addresses in each flow between different interfaces in the flow information table 62, to identify a set of flows in which only one of a destination IP and a transmission source IP equals, to identify a VM in which a virtual router performing NAT conversion is implemented.SELECTED DRAWING: Figure 3 |
