Video conference optimization technical method under transparent mode

Abstract

The invention provides a video conference optimization technical method under a transparent mode. According to the invention, video transmission optimization equipment is deployed at the exit of a local area network of participants of a video conference based on a transparent mode, a video stream needing transmission is transmitted from a layer L2 to a layer L3 and processed, the UDP of the video stream is packaged into a TCP packet by a VPN tunneling technology, video transmission in a VPN tunnel is accelerated by a TCP acceleration technology, and therefore, mosaic, jamming, jittering and other problems of the video screen are solved effectively. Meanwhile, the video transmission optimization equipment 103 can guarantee the video transmission link of the video conference, and when the video transmission link of the video conference fails, and the video conference can be switched to other available spare links and is thus not interrupted. According to the invention, there is no need to change the original network structure and routing configuration of the local area network, accelerated and optimized transmission under a TCP (Transmission Control Protocol) is realized, the TCP acceleration and optimization technology is utilized to the maximum, and guarantee to the video transmission link is improved.

Description

technical field [0001] The present invention relates to the technical field of communication related to video conferencing, in particular to a method and system for optimizing video conferencing based on a transparent mode. Background technique [0002] With the continuous development of multimedia technology and digital communication technology, video conferencing system has become an important means to realize multi-party real-time remote communication, and it is one of the indispensable forms of work communication. Set up a video conferencing system. Video conferencing not only improves communication efficiency, but also reduces communication costs. [0003] Because video conferencing is a real-time multimedia application based on network communication technology, it has high requirements on network bandwidth, transmission delay, packet loss rate and so on. In practical applications, considering the cost factor, most video conferencing systems use WAN as the bearer netw...

Problems solved by technology

Due to the need to change the routing configuration of other network devices, this deployment method is more complicated to operate, which increases the difficulty and complexity of deployment.

[0006] On the other hand, the video data stream generated in the video conference is transmitted using the UDP protocol, so the transmission optimization equipment can only perform compensation and optimization on the video data stream on the basis of the UDP protocol; this makes the transmission optimization technology based on IP packets, such as The above-mentioned packet loss detection and retransmission, IP packet repetition control, etc., cannot be well applied to the optimization of video streams using UDP protocol, so it cannot effectively solve the problem of mosaic, freeze and Situation of suspension
