The feature of native system is such: MCU resource, server, public network client, Internet.Wherein the MCU resource provides the video information of meeting-place just in session,, server links to each other with Internet, and the public network client links to each other with Internet, links to each other with server by the Internet.Wherein server end is placed with control program, user supervisor, and the public network client is placed with video information and receives program, video information transmission program and control program, video reproduction program, video coding program, video decode program.
The characteristics of native system are: each public network client is linked server by Internet.Server is assessed this public network client according to the situation (comprising the network bandwidth, level of hardware etc.) of each public network client.And therefrom select a collection of conduct " secondary server " according to assessment result, these " secondary servers " form a series of " zone " with other public network client.Server is according to comprehensive condition guiding " secondary server " networking of this " secondary server ".Which select by " secondary server " to be connected with the MCU resource according to the comprehensive condition of each " secondary server " and MCU resource then." secondary server " broadcast conference video information, obtain the meeting-place end message that is broadcasted and needs video access meeting (speech of raising one's hand), give an order to the MCU resource, with this meeting-place formal invitation and insert this meeting, take a fixedly MCU port resource.
Certain terminal is passed through dual mode and is access in the MCU meeting in the networking video conferencing system as required, makes a speech:
1. server command access way:
Certain terminal in the networking video conferencing system as required need be linked into the audio/video information of this locality in the meeting that MCU holding, this terminal need be sent application to server, server sends the solicited message of related command and this terminal to the MCU control end, after the MCU control end receives order, invite this terminal to make a speech according to terminal information.This terminal is gathered local audio/video information and is sent the MCU control end to by local audio-video collection equipment.
2. MCU orders access way:
Certain terminal in the networking video conferencing system as required need be linked into the audio/video information of this locality in the meeting that MCU holding, this terminal need be sent request to server, server sends to the MCU control end to the solicited message of this terminal, the solicited message of this terminal is identified and shown to the MCU control end, the invitation meeting-place function of passing through MCU self inserts this terminal in this meeting, and by checking that functions such as meeting-place, broadcast site are linked into meeting with the audio/video information of this terminal.
Public network client in " secondary server " guidance field is carried out networking according to certain rule." secondary server " can be selected according to the comprehensive condition of the public network client in the zone and the concrete needs in the zone: " standby secondary server ", " top-tier customer end "." standby secondary server ", " top-tier customer end " are taken on the trunk node in the zone role.In the time of can't continuing to serve as " secondary server " under " standby secondary server " emergency case such as " secondary server " generation disaster in the one's respective area simultaneously, the role that can take on " secondary server ".
The superior node of " standby secondary server " generally all is " secondary server ", the superior node of top-tier customer end generally all is " standby secondary server ", and the superior node of normal client end generally all is top-tier customer end or " standby secondary server ".Certainly the normal client end also can be used as superior node, but in principle can only be as the superior node of other normal client ends.To form one be the tree of root node with " secondary server " by being linked at " zone in " so layer by layer.
The advantage of comparing existence with other system of native system has: by server whole network is divided into district system in " secondary server " being one by one, can the most effectively utilizes the high-quality resource in the whole system.
