Estimation method, device, and program, and network measuring system
Abstract:
An inversion of a packet transmission sequence number is observed in a predetermined sampling measurement. The number of sampled sequence numbers greater than the sequence number upon the inversion is measured as an inversion degree. A number of packet losses or a loss ratio is estimated according to the inversion degree under the estimated full sampling measurement and the inversion degree observed under a predetermined sampling measurement.
Abstract(Chinese):

在预定的采样测量中观察到分组传输序列号的反转。 测量大于反转时的序列号的采样序列号的数量作为反转度。 根据在预定的全采样测量下的反转程度和在预定采样测量下观察到的反转程度来估计多个分组丢失或丢失率。
