IDENTIFICATION METHOD AND DEVICE FOR LOST DATA PACKET

Provided is a method and device for identifying a lost data packet, wherein the method includes: when a first synchronization sequence in which a received synchronization packet is located includes a control packet, packet numbers of data packets in the first synchronization sequence are uniformly sorted, wherein the packet numbers include: a packet number of a data packet and a packet number of the control packet; and when the packet numbers in a sorting result are discontinuous, a data packet corresponding to a lost packet number in the sorting result is taken as a lost data packet. The technical solution provided in the disclosure solves the problem that there is no effective technical solution, which is able to identify one or more lost packets in a received packet rapidly and accurately, in related art, and then the lost data packet can be rapidly and accurately determined in the received packet.
