PROBLEM TO BE SOLVED: To provide a link quality measurement device, its flow entry aggregation method and program capable of reducing the number of flow entries of packets for measurement registered in each switch on a network.SOLUTION: A network 20 includes: an OpenFlow controller 201; a plurality of OpenFlow switches; and a plurality of hosts. In a server device 1, a measurement path calculation part 101 calculates the communication paths of test packets, and acquires the group of the communication paths of the test packets. A flow entry aggregation part 102 aggregates the flow entries of the test packets which pass through the switch registered in each switch in accordance with the calculation result of the communication paths to reduce the number of the flow entries. A communication path setting part 103 registers the aggregated flow entries from the controller 201 to each register. In a measurement terminal, a measurement execution part 104 executes measurement processing to transmit and receive the test packets, and to estimate the communication quality of each link from observation data. |
