<p>In a network quality measurement device, it is possible to accurately count the number of data losses even when all of the packets to be counted are not acquired or cannot be acquired. By processing only some of the packets to be counted, it is possible to reduce the processing load on the measurement device. The measurement device for performing quality measurement includes: means for estimating the sampling ratio according to the number indicating the sequence and the number of reception data stored in the packet; and means for estimating the data loss which would be counted when all the packets are acquired, according to the sampling measurement result by performing differentiation processing and the statistic processing by using the sequence in the packet. Thus, during sampling measurement, the number of data losses is counted.</p> |
