Abstract: A method, device, and system for measuring network packet loss. A sender performs data packet counting processing on a service stream sent to a receiver to obtain a first data packet count corresponding to a measurement period identifier. The sender sends an OAM packet including a measurement period identifier to be queried to the receiver. The OAM packet and a data packet of the service stream are transmitted on a same path. The sender receives a second data packet count that is returned by the receiver after the receiver receives the OAM packet. The second data packet count is a count obtained by the receiver by performing data packet counting processing on the received service stream. The sender determines a network packet loss situation according to the first data packet count and the second data packet count.
