Problems solved by technology

[0004] The introduction of FEC coding is to use a certain amount of redundant traffic to repair error packets or packet loss in network transmission, but using the same redundancy in different network environments may cause traffic waste or insufficient error correction of FEC coding

Abstract

The disclosure relates to a data transmission method and device, electronic equipment and a storage medium, which relate to the technical field of data communication and can be applied to data transmission scenes in which the network status changes in real time. The method comprises the following steps that: a transmitting end transmits data encapsulated by a repeat protocol layer and a forward error correction coding layer to a receiving end, and sends a data transmission message to the receiving end periodically; the receiving end determines a data packet loss rate according the data transmission message and a data receiving condition, and returns the packet loss rate to the transmitting end; and the transmitting end dynamically adjusts forward error correction coding parameters according to the data packet loss rate, and transmits data undergoing forward error correction coding to the receiving end. Through adoption of the data transmission method and device, the coding parameters for coding transmission data can be adjusted dynamically according to the data packet loss rate under the condition of real-time change of the network status, so that the waste of flow during transmission is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of data communication, and in particular, to a data transmission method, a data transmission device, electronic equipment, and a storage medium. Background technique [0002] At present, data transmission is mainly based on User Datagram Protocol (User Datagram Protocol, UDP) or Transmission Control Protocol (Transmission Control Protocol, TCP). Reliable, data loss may occur due to out-of-order packet loss. [0003] Therefore, an active retransmission technology or a forward error correction code (Forward Error Correction, FEC) technology is introduced into the UDP protocol to realize data transmission. The introduction of Automatic Repeat-reQuest (ARQ) can improve the data transmission based on UDP protocol to a certain extent, but if the retransmission strategy is improper, it will introduce a large amount of retransmission data, and it may not be able to guarantee data security. reliability. ...
