Problems solved by technology

[0003] However, the quality of online video conferencing has high requirements for real-time performance. After many experiments by users, it has been found that most video conferencing systems currently have audio and video communication obstacles caused by bandwidth congestion and large delays at the egress of the LAN. The image cannot be distinguished, the sound is intermittent or even interrupted, the signal lags behind, and the picture is not continuous, etc.

Embodiment

[0041] Such as figure 1 As shown, the network video conferencing system based on video traffic acceleration includes more than one client with network video conferencing software installed, a router connected to the client through the network, a marking module is also set on the client, and The router is provided with a queue module and a data scheduling module sequentially connected to the marking module; the data scheduling module forwards the data packets according to the priority principle in the queue module.

[0042] The environment and requirements of the present invention: the line is ADSL (3M / 512K); eth0 is the pppoe external network port; eth1 is the 192.168.0.1 internal network port.

[0043] The business requirements of the present invention are: to identify normal video conference traffic, ensure that such traffic is preferentially forwarded by routers, and restrict all other applications so as not to affect the use of normal business. The forwarding queue is div...

Abstract

The invention discloses a network video conferencing system based on video signal flow acceleration and an acceleration method thereof. The system comprises clients installed with network video conference software and routers connecting with the clients through a network. The clients are provided with mark modules. Queue modules and data scheduling modules which are connected with the mark modules in order are arranged in the routers. The quantity of the routers is two or more, and all routers are connected with wired networks or wireless networks. According to the invention, normal video conference flow is identified to guarantee the preferential forwarding of this kind of flow by routers and restrict all other applications so as not to influence the usage of normal services.

Description

technical field [0001] The invention relates to the field of network video conferencing systems, in particular to a network video conferencing system based on video traffic acceleration and an acceleration method thereof. Background technique [0002] Video conferencing realizes virtual meetings through network communication technology, gathers geographically dispersed users in one place, exchanges information through various methods such as images and sounds, and carries out collaborative work. Video conferencing shortens the spatial distance to the greatest extent and facilitates real-time and intuitive communication among collaborative members. [0003] However, the quality of online video conferencing has high requirements for real-time performance. After many experiments by users, it has been found that most video conferencing systems currently have audio and video communication obstacles caused by bandwidth congestion and large delays at the egress of the LAN. The ima...
