Description
Technical field
The present invention relates to a kind of many streaming media servers.It is more particularly to a kind of to solve based on many Streaming Media clothes of udp protocol
The method of device crossfire phenomenon of being engaged in.
Background technology
With the popularization of internet and developing rapidly for electronic equipment, stream media technology turns into indispensable during people live
Few part, such as major internet music websites, online cinema and monitoring system are all that one kind of stream media technology should
With.Particular for monitor in real time field, because udp protocol occupies absolute excellent in the very strong data transportation requirements of real-time
Gesture, therefore the alternating transmission of Media Stream is carried out using udp protocol to the monitoring of real-time video.But because udp protocol is deposited in itself
Client is sent data in the non-intellectual of one kind, i.e. server, server is not aware that client, either with or without normally receiving, is serviced
After device receives transmission order, just constantly data are sent toward the client specified.So when client is anticipated for some reason
During outer stopping, server is not known, and still adheres to sending data toward the client, when the client again requires that reception clothes
During business device data, the data for sending together twice will be now received, this scene is referred to as crossfire in video monitoring shows
As.
In streaming media service, crossfire is that, using a kind of phenomenon of udp protocol generally existing, crossfire on-the-spot meeting occur and cause
There is Huaping phenomenon in monitored picture, and image cannot almost be watched, and how to effectively eliminate the crossfire phenomenon based on udp protocol for journey
Sequence develops problem in the urgent need to address.
Streaming media server major function is in the form of streaming by audio files information transfer to client, for client
End viewing；Can also from the collection of video, compression, receive live video stream, it is then live to client with stream protocol, supervised in real time
In control system, due to using the mechanism transmitted nearby, multiple streaming media servers, each Streaming Media clothes can be disposed in different places
Business device is only used as the treatment and forwarding of Media Stream, and the maintenance of business datum is not related to, i.e., be independent between each streaming media server
Exist, will not be interacted between each streaming media server.
Client video is had access to, and client can select a certain video to send instructions to streaming media server to be carried out taking stream sight
See, what each client can be apparent from knows the stream transmission information for having access to situation and each streaming media server of itself.
The content of the invention
The technical problems to be solved by the invention are to provide and a kind of can carry out each independent streaming media service well
Interactive method of the solution based on many streaming media server crossfire phenomenons of udp protocol.
The technical solution adopted in the present invention is：It is a kind of to solve to be based on many streaming media server crossfire phenomenons of udp protocol
Method, comprises the following steps：
1) client video control is initialized when successfully, and the video control of client obtains client ip；
2) crossfire that the IP of acquisition is sent to JAVA servers is detected instruction interface by client；
3) stream information retrieval：The interface that JAVA servers are reserved by streaming media server, obtains current streaming media service
The stream information sent in device, and be examined in transmitted stream information IP whether the IP phases with the client for being received
Together, if identical, the stream information for sending is considered as the exception stream for needing to close；
4) transmission of stream information is closed：In the non-normal switching-off stream result of stream information retrieval, JAVA servers are to stream matchmaker
Body server sends the instruction for closing stream, and the stream to non-normal switching-off sends out code successively, by the non-normal switching-off
Stream is closed.
During client initialization success, it is confirmed that the client does not ask to receive any stream information, as long as therefore stream matchmaker
The stream information that oriented described client sends in body server belongs to the stream of non-normal switching-off, is now turned off.
It is of the invention to solve the method based on many streaming media server crossfire phenomenons of udp protocol, with following features：
1st, it is combination by server and client, the generation of crossfire phenomenon is solved well；
2nd, streaming media server is that convection current makes requests on and forwards, and some business datums are safeguarded and are not placed on streaming media service
In device, its complexity can be so reduced, ensure the durability and the independence with other systems of streaming media service, reach low coupling
The effect of conjunction；
3rd, each independent streaming media service can well be interacted.
Also, the present invention can reach following beneficial effect：
1st, streaming media service Focus, independent：Streaming media service only focuses on acquisition and the forwarding capability of Media Stream, without
Go to be concerned about some operational control logics, be so more beneficial for the independence of intermodule, improve the durability of streaming media service.
2nd, server resource consumption is reduced：One platform, because the rule of life of people result in platform and also have and people
Same enlivens rule, and platform can process more users' operations when general daytime, but to evening, platform is almost located
In idle condition, and it is in fact now not need timed task to go to detect some stream informations again, causes unnecessary resource consumption,
This ingenious utilization client of invention is initialized every time goes to detect stream information instead of timed task, so when customer volume is little,
Naturally also just reduce resource consumption
3rd, it is interactive between enhancing streaming media server：The principle of stream is taken due to storing nearby, stream week is reduced as far as possible then is lost
More bags, therefore multiple streaming media services are often disposed in a platform, and it is mutually only when between these streaming media services
Vertical, they are simultaneously unaware of the presence of other streaming media servers, and detection module is placed on java service ends by the present invention, because only
Have java service ends just know this platform which streaming media server, therefore java service ends can preferably manage these moneys
Source, the resource all unification related to business is placed on java service ends, centralized management treatment.

Specific embodiment
It is existing based on many streaming media server crossfires of udp protocol to a kind of solution of the invention with reference to embodiment and accompanying drawing
The method of elephant is described in detail.
A kind of method for solving to be based on many streaming media server crossfire phenomenons of udp protocol of the invention, is as shown in Figure 1
System in realize, comprise the following steps：
1) client video control is initialized when successfully, and the video control of client obtains client ip：Detection client
Which stream is belonging to the foundation of normal switching-off stream information in IP, is foundation stone of the invention, during due to client initialization success, just
Can confirm that the client does not ask to receive any stream information, as long as therefore oriented described client in streaming media server
The stream information of transmission belongs to the stream of non-normal switching-off, should now be turned off；
2) crossfire that the IP of acquisition is sent to JAVA servers is detected instruction interface by client：This part major responsibility is
By client ip identity by being sent to JAVA servers, streaming media server is set to know that client needs to detect stream information
Transmission situation；
3) stream information retrieval：The interface that JAVA servers are reserved by streaming media server, obtains current streaming media service
The stream information sent in device, and be examined in transmitted stream information IP whether the IP phases with the client for being received
Together, if identical, the stream information for sending is considered as the exception stream for needing to close；
4) transmission of stream information is closed：In the non-normal switching-off stream result of stream information retrieval, JAVA servers are to stream matchmaker
Body server sends the instruction for closing stream, and the stream to non-normal switching-off sends out code successively, by the non-normal switching-off
Stream is closed：The stream information of the non-normal switching-off is closed, the client is thus effectively prevented before video is had access to
There is no unnecessary stream, the generation of crossfire phenomenon is prevented well.
Application of the invention is illustrated with the example in Fig. 2 below.
1st, during the success of client video plug-in initialization, it may be determined that the client does not have access to any video, now obtains
Client ip address；
2nd, client sends to the crossfire detection interface of background java server the IP address of 1 Procedure Acquisition；
3rd, JAVA servers send a command to each streaming media server, obtain the stream sent in each streaming media server
Information；
4th, JAVA servers receive the stream information that each stream matchmaker server is replied；
5th, the client ip address obtained in the IP address and 2 of the stream for sending that JAVA servers are received 4 is compared,
If identical, the stream is the exception stream of last time non-normal switching-off；
6th, JAVA servers are sent and close stream instruction to streaming media server, and the exception stream being not turned off that 5 detect is closed
Close.
7th, after detection is finished, you can remove the exception stream that the client is normal switching-off, effectively prevent from being normal switching-off
The crossfire phenomenon that stream is caused.
