Abstract

The invention provides a data packet management method and device. The data packet management method comprises the following steps: receiving an RTP data packet; acquiring data information of the RTPdata packet, caching the RTP data packet into a cache queue according to the data information of the data packet; sorting the RTP data packets; after the RTP data packet is received, sending the RTP data packet to the server; sorting according to the data information of the RTP data packets, so that when the RTP data needs to be recombined, the RTP data packets can be recombined according to the sequence of the RTP data packets; after the RTP data packet is obtained, in order to ensure the integrity of each frame of picture, judging whether the RTP data packet at the head position is a starting packet of a video frame or not; after obtaining a starting packet of a video frame, searching an ending packet of the video frame, obtaining an RTP data packet between the starting packet of the video frame and the ending packet of the video frame, and then recombining RTP data to obtain a video stream, thereby avoiding influencing the recombining of the RTP data when an expired packet appears.

Description

technical field [0001] The present application relates to the technical field of intelligent transportation, in particular to a data packet management method and device. Background technique [0002] In the process of data transmission, in order to speed up the data transmission efficiency, data will be transmitted based on UDP (User Datagram Protocol, User Datagram Protocol), but when transmitting RTP (Real-time Transport Protocol, real-time transport protocol) data based on UDP protocol, due to There is an MTU (Maximum Transmission Unit) limitation during the transmission process, which leads to the need to divide the data into multiple data packets smaller than the MTU during the data transmission process. However, when transmitting data based on the UDP protocol, the received The data packets are not arranged in order, so after receiving the data packets, it is necessary to search for each data packet according to the order of the data packets, and then reassemble the da...
