3. distribute and dispose the entrance that has increased network, reduced the pressure of central access, effectively reduced network pressure, increased the life-span of network.
4. after setting up WebSocket and connecting, need to not shake hands separately, and the data that send do not comprise header packet information at every turn, accelerated the speed of the transmission of messages between each level.
[accompanying drawing explanation]
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the theory diagram that the present invention is based on the distributed broadcast system embodiment of WebSocket agreement.
Fig. 2 is the schematic diagram that the present invention is based on the distributed broadcast system embodiment simulated scenario of WebSocket agreement.
[embodiment]
As shown in Figure 1, the distributed broadcast system based on WebSocket agreement comprises the main control server that connects by network, many distribution server, many mobile terminals and terminal.
Necessary software is installed on each server, and JDK, container (Tomcat, Jetty8.0 and more than), at main control server end, dispose controlling application program; On distributed server, dispose the service of corresponding primary control program, and be configured corresponding with main control server.Main control server by the pattern of WebSocket, is distributed to distributed server message, and distributed server, by the form of WebSocket, is distributed to mobile terminal and PC terminal.
Wherein, main control server is responsible for the control of program, the work such as distribution of the management of data, information.
Distribution server is responsible for the transmitting-receiving with main control server and end message, has played a connecting bridge beam action.
Terminal is responsible for receiving the broadcast of distribution server, submits the operation of terminal to.Distribution server both can independently be processed the affairs of various terminals, also can carry out alternately with other distribution server.
Main control server is set up WebSocket with each distribution server respectively and is connected, and carries out the reception of data.
Each distribution server has a WebSocket connection pool, for various terminals, grow connection, and by the broadcast technology of WebSocket, give each terminal PUSH message, can also monitor at any time the state of connection, if connected, disconnect, just receive and send message to this chain, can lower the WebSocket broadcast pressure of distribution server.
PC terminal or mobile terminal, only need to set up a WebSocket with distribution server and be connected, just can receiving broadcasting information.Terminal is by http protocol, completes mutual with distribution server.
Main control server of the present invention is disposed a set of management application, other distributed servers are disposed agent application, terminal has request, mutual prior to should being used as of proxy server, then proxy server sends request to host applications, and main control server is processed the request sending is unified, and upgrades data source, finally the data source of upgrading is sent to all distribution server agent application, then send to each terminal by agent application.
The invention belongs to the organizational structure of center-control, basic unit's broadcast, adopt the technology of WebSocket to carry out the communication between different frameworks, can significantly reduce the pressure of network, effectively increase network life, improve the response speed of terminal, and the reception of support pc client, WEB end and mobile terminal (IOS, Android, WP8) data.
As shown in Figure 2, a scene of embodiments of the invention 2 simulation electronic meetings illustrates the course of work of the present invention: the content of simulated scenario is, host's operating mobile terminal device A, carries out the page turning of PPT, operation is sent to each terminal of participating in electronic meeting.
Precondition in simulated scenario is: server is normally operation all, and main control server, terminal are all connected with distribution server.
1. mobile terminal A operation ppt carries out page turning, after page turning completes, sends a HTTP request, gives distributed server.
2. distributed server, by WebSocket passage, the information of user's request, is issued main control server.
3. main control server receives after information, carries out, after inter-process, the information exchange that broadcast being crossed to WebSocket passage, issues the distribution server in Beijing, Shanghai, Shenzhen.
4. distribution server receives after the broadcast of master control, and this message, by the broadcast mode of WebSocket passage, is issued to all terminals that connected, and finally each terminal receives after message, carries out the operation of page turning.
Because information is in mutual process, transmission speed is very fast, can reach the effect of real-time page turning.
The present invention has following beneficial effect:
1.WebSocket, unlike HTTP, needs to shake hands for 3 times at every turn, ability request message, and after having asked, link interruption, alternately, again shakes hands again, asks, interrupts if also need to continue.WebSocket only needs 1 once to shake hands, and just can send message, and keeps this link not interrupt, in each receipt sending, the gauge outfit information that does not comprise HTTP, so can reduce the time of request and the data volume of request, the present invention can significantly reduce mutual data volume and time.
2. can realize the broadcast of cross-network segment: no matter be that main control server arrives distribution server, or distribution server is to terminal, can carry out cross-network segment transmission of messages.Distribution server, can cross-network segment broadcast to the transmission information of terminal.Traditional broadcast mechanism adopts Socket mode, can only be to carry out information broadcast for some network segments, for example: can only send 192.168.1.1-192.168.1.254 to secondary network, send to this network segment of 192.168.2.1.If realize, cumbersome, incessantly to arrange hardware, and also higher to the performance requirement of hardware.
3. alleviate the pressure of server, and transmission is encrypted, guarantee that the Secure Web Socket of data is in the process of shaking hands, become to produce the key of a MD5, in the time of each interaction data, adopt this key to carry out Base64 encryption to data, so just prevent the deciphering after data are revealed, because key is preserved in both sides' hand again, can also prevent the WebSocket solicited message of personation.
4. support the data interaction (IOS, Android, WP8) of mobile terminal: if web end and server interaction can, in webpage, be called the WebSocket object of Js; WebSocket object and server interaction in the above version of pc customer end adopted Jetty8; Mobile terminal, for IOS or Android, adopts the third party WebSocket class libraries of increasing income, with server interaction; The mode of three kinds of above connections is as follows: with ws beginning, and to server request, for example, ws: // 192.168.1.34:8080/server/chart.do).
