摘要： 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.
