Data transmission method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention provides a data transmission method and device, electronic equipment and a storage medium, the method can be applied to a monitoring system, and the monitoring system comprises a server and a client; the server comprises a first main user datagram protocol UDP port and a first standby UDP port, and the client comprises a second main UDP port and a second standby UDPport. According to the embodiment of the invention, data transmission between the server and the client can be realized; and if the residual space of the buffer area of the current UDP port of the data receiving end for data transmission reaches a certain threshold value, the server and the client are switched to another UDP port for data transmission, so that data packet loss of the data receiving end due to the fact that the residual space of the buffer area of the UDP port is too low is avoided.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a data transmission method, a data transmission device, electronic equipment, and a storage medium. Background technique [0002] The video monitoring system can realize a visual remote monitoring of specified scenes and objects by collecting video data. Video surveillance systems are also increasingly popular in people's lives. For example: traffic monitoring, public security monitoring, indoor monitoring, etc. [0003] In an existing video surveillance system, it is generally necessary to transmit surveillance data (eg, video data). Specifically, a UDP (User Datagram Protocol, User Datagram Protocol) Socket (socket) is set at the receiving and sending ends of the monitoring data, and the UDP socket is used for data transmission. [0004] However, in the existing scheme of using UDP sockets to transmit monitoring data, there may be insuff...

Problems solved by technology

[0004] However, in the existing schemes that use UDP sockets to transmit monitoring data, there may be insufficient information on the remaining buffer space of UDP sockets, resulting in packet loss of monitoring data, and the complete monitoring data cannot be transmitted.
