Data transmission method and data transmission device of video conferencing system

Abstract

The present invention provides a data transmission method and a data transmission device of a video conferencing system. The method includes: a management node selects a main media node and an auxiliary media node according to the characteristics of the terminal and the current instantaneous traffic of the media node; the terminal connects to the main media node Upload or download data; if the main media node exceeds the first water level for a continuous preset time, the terminal is no longer allowed to access; if the instantaneous flow of the main media node exceeds the second water level for a continuous preset time, judge the secondary Whether the media node has the ability to forward, if so, the primary media node transfers the remaining data packets to the secondary media node, and the secondary media node transmits the remaining data packets according to the preset destination address. The present invention can forward the remaining data packets of the media nodes exceeding the instantaneous carrying capacity to the pre-designated standby media nodes, so that the terminal can always receive continuous data packets, and solves the problem of the video conferencing system being stuck and blurred due to the instantaneous overload of the server .

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method for a video conferencing system, another data transmission method for a video conferencing system, a data transmission device for a video conferencing system, and a non-transitory computer-readable storage medium and a computer device. Background technique [0002] Due to the large number of participants in large-capacity video conferencing, the video conferencing system adopts the mechanism of media forwarding. The media forwarding service does not mix audio and video. After receiving the audio and video stream sent by a certain terminal, it directly transfers the audio and video stream. Send to other terminals in the room. The system provides multiple media service nodes to form a media forwarding cluster, and the load balancing management service distributes the media nodes. [0003] In related technologies, the following technical s...

Problems solved by technology

[0008] In order to solve the above-mentioned technical problems, the present invention provides a data transmission method of a video conferencing system, which can forward the remaining data packets of media nodes exceeding the instantaneous carrying capacity to a pre-designated standby media node, so that the terminal receives Continuous data packets are always received during the process, which solves the problem of data congestion or packet loss caused by media nodes due to bandwidth overload in video conferencing scenarios, which eventually leads to poor conference results and insufficient utilization of media server resources, and satisfies the bandwidth fairness of video conferencing system forwarding services Allocation strategies and the principle of sharing are taken into account to maximize the use of resources
