IP SINGLE-PASS DETECTION METHOD AND IP SINGLE-PASS DETECTION DEVICE

摘要

Embodiments of the present invention relate to an IP single-pass detection method and an IP single-pass detection device. The method of an embodiment of the present invention comprises: in a detection period, obtaining a serial number of a received first real-time transfer protocol frame, a serial number of a received last real-time transfer protocol frame and the total number of received packets; according to the serial numbers of the first and the last real-time transfer protocol frames, calculating the expected number of received frames in the detection period; according to the expected number of received frames and the total number of received packets, calculating a frame loss ratio in the detection period, and if a synchronization source symbol of the received real-time transfer protocol frame maintains unchanged, a jump value of the serial numbers of any two adjacent real-time transfer protocol frames is less than or equal to a jump threshold, the expected number of received frames is greater than or equal to a valid frame threshold, and the frame loss ratio is greater than or equal to a first single-pass detection threshold, judging that IP single-pass occurs in the detection period. The embodiments of the present invention can avoid erroneous judgment in IP single-pass detection caused by subjective feelings of a user.
