Embodiment Construction

[0029] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] In one-to-many or many-to-many communication scenarios, if a pair of video links occupies too much network bandwidth, due to limited network bandwidth, the available bandwidth of other links will inevitably decrease, resulting in packet loss, which in turn leads to It is difficult for the receiving terminal to receive the complete UDP ...

Abstract

The invention relates to the technical field of audio and video data transmission, and discloses a UDP data packet transmission control method, device, equipment and readable storage medium. The method includes: acquiring transmission information of the UDP data packet, the length of the last sending queue and the size of the last sending control window; judging whether the UDP data packet is lost; when the UDP data packet is lost, based on the length of the last sending queue and the size of the last sending control window, calculate the target sending control window for transmitting UDP data packets; adjust the sending control window for transmitting UDP data packets according to the size of the target sending control window. By implementing the present invention, the problem of continuous loss of UDP data packets in the one-to-many communication process and affecting the communication quality is avoided, and it is ensured that all parties in the communication can receive the UDP data packets transmitted by the sender in time, thereby realizing the fairness of data transmission. The communication quality of the communication parties is taken into account.

Description

technical field [0001] The present invention relates to the technical field of audio and video data transmission, in particular to a transmission control method, device, device and readable storage medium of UDP data packets. Background technique [0002] Since the transmission of audio and video is very sensitive to network delay, the UDP protocol is generally used for audio and video data transmission in the prior art. With the development of network technology, UDP-based audio, video and p2p shared resource applications gradually occupy most of the Internet bandwidth. In the scenario of one-to-one communication, the network environment can generally meet the bandwidth requirements. However, the actual network environment is usually multi-channel sharing the same link, that is, one-to-many communication, or even more than multiple channels sharing the same link. In this communication scenario, if a pair of video links occupies too much network bandwidth, the available ban...
