QUALITY MEASURING DEVICE, QUALITY MEASURING METHOD, AND QUALITY MEASURING PROGRAM

To reproduce and measure a network load that occurs suddenly. A quality measurement device 1 includes a load analysis unit 21 which analyzes a load of a measurement target network 2, a reference load acquisition unit 22 which acquires reference load data 14 including a load of a reference network 3, a test condition determination unit 23 which determines, based on a load at a reference point of the reference network 3, a load to be added to a measurement point of the measurement target network 2 corresponding to the reference point, and a test traffic generation unit 24 which gives traffic corresponding to the load that is determined to the measurement point.
