Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is done and to be elaborated.VAU is linked into the whole video supervisory control system.Video monitoring system comprises: media transcoding units, front monitoring front-end, mobile client, fixed network streaming media server and mobile flow medium server.Video monitoring system include but not limited to adopt real-time streaming protocol (Real Time Streaming Protocol, RTSP) or session initiation protocol (Session Initiation Protocol, video monitoring system SIP).Concrete, see also Fig. 1, wherein,
VAU is the key network element that realizes mobile service network and the intercommunication of global eyes platform, realizes the service interaction between mobile service network and the global eyes network.The high bandwidth code stream that front monitoring front-end is uploaded converts terminals such as mobile phone to and watches needed mobile code stream.
(Pre Unit PU), is responsible for finishing the functions such as collection, buffer memory, coding, storage and transmission of audio/video information, warning information, and can receives the control command of automatic network front monitoring front-end.
(Mobile Client Unit, M_CU), the Business Initiator finishes decoding and broadcast, the transmission cloud mirror of parsings such as service request/initiations such as authentication, the watch-list page, video flowing and controls functions such as (PTZ) message mobile client.
(Streaming Server, SS), major function is to carry out the forwarding of medium code stream and storage etc. to the fixed network streaming media server, receives the medium code stream of front monitoring front-end, and it is transmitted to VAU or fixed network client, stores as required simultaneously.
Mobile flow medium server (PSS, Packet-switched Streaming Server), this equipment belongs to optional equipment.It is the network element of handling the Media Stream distribution in the system.Main customer in response end (M_CU) business request information is obtained the Streaming Media distribution procedure of streaming medium content to M_CU in real time with collaborative the finishing from VAU of M_CU, VAU.
Front monitoring front-end sends code stream to the fixed network streaming media server, and VAU carries out transcoding output as requested after the fixed network streaming media server obtains the medium code stream.
Any VAU in media transcoding network VAU that both can decide also can do from VAU, determines by configuration file.Can be connected on the main VAU by the Remote configuration tool software, add to need main VAU management from VAU information (as user name, password etc.).Find it oneself is that main VAU just starts a thread and intercepts connection from VAU if read configuration file during device start, handle registration from VAU, keep-alive etc.; If find oneself is just to initiate register requirement etc. to main VAU (its IP, port also obtain by configuration file) from VAU.In order to improve reliability, can dispose the standby host of a main VAU according to circumstances.
The load balancing implementation method may further comprise the steps:
A, selected VAU is as main VAU in the VAU network, and all the other VAU are as from VAU.Main VAU is in charge of, dispatches the resource of whole VAU network.To dispose information such as user name from VAU, password at the lane database of main VAU.For improving reliability, main VAU can consider dual-host backup.
B, start the back from VAU and register (password is advised with encryptions such as MD5) according to configuration information to main VAU, main VAU is to verifying authentication from VAU.Checking by after just allow from VAU carry out follow-up reaching the standard grade, the keep-alive flow process.
C, then initiatively initiate the keep-alive request from VAU in keepalive period, subsidiary ability information (comprising CPU, memory usage, transcoding, transparent transmission, distribution way etc.) to main VAU.When the VAU ability changes with the form real-time report of keep-alive message.From VAU does not receive main VAU in continuous a plurality of keepalive periods response, then think keep-alive failure, get back to step B); Main VAU does not receive the keep-alive request from VAU in continuous a plurality of keepalive periods, then think keep-alive failure, this VAU is changed to rolls off the production line.
D, starting point M_CU/PSS sowing time send order request to main VAU.The information that main VAU obtains according to step C is selected the VAU of load minimum what reached the standard grade from VAU, and judges whether this VAU transships (threshold value can be provided with).
If the VAU nonoverload that E step D chooses just provides service by this VAU for the client, main VAU then returns redirected (redirection recommends 302) response to M_CU/PSS.M_CU/PSS initiates request to this from VAU again according to the URL from VAU that Location returned in the response message, and it is mutual to finish follow-up signaling and medium.
If the VAU that F step D chooses overload directly provides service by main VAU under the situation of main VAU nonoverload.Whole VAU network over loading is described if main VAU also transships, and need remind operator's upgrade expanding this moment to network management alarm; Denial of service simultaneously.
If the G existing network transships then needs dilatation.On main VAU, add the information of a new VAU, allow its registration, reach the standard grade.Can allow the VAU that newly reach the standard grade for it provide service when new order request is arranged this moment, can not influence existing business, reaches the purpose of smooth expansion.
Any VAU in media transcoding network VAU that both can decide also can do from VAU, determines by configuration file.Can be connected on the main VAU by the Remote configuration tool software, add to need main VAU management from VAU information (as user name, password etc.).Find it oneself is that main VAU just starts a thread and intercepts connection from VAU if read configuration file during device start, handle registration from VAU, keep-alive etc.; If find oneself is just to initiate register requirement etc. to main VAU (its IP, port also obtain by configuration file) from VAU.In order to improve reliability, can dispose the standby host of a main VAU according to circumstances.
See also Fig. 2, the information interaction between the master and slave VAU comprises:
201, send register requirement from VAU to main VAU, when registering, main VAU need carry self Internet protocol (Internet Protocol from VAU, IP) address, real-time streaming protocol (Real TimeStreaming Protocol, information such as serve port RTSP), user name and password.
202, main VAU verifies authentication to this register requirement.
203, after the checking authentication was passed through, main VAU was to responding from the registration of VAU feedback.(IDentity ID) is convenient to management to main VAU to distribute a unique identify label number of the whole network from VAU in the registration response.
204, succeed in registration the back from the VAU initiation request of reaching the standard grade.
205, main VAU gives parameters such as returning keepalive period from VAU in the response of reaching the standard grade.
206, reach the standard grade after the success, initiate the keep-alive request from VAU.In the keep-alive request, to carry the loading condition parameter (comprising CPU, memory usage, transcoding way etc.) of self, be convenient to main VAU and carry out load balancing and calculate from VAU.
207, main VAU is to responding from the keep-alive of VAU feedback.Main VAU also can be returned keepalive period from VAU in the keep-alive response, mainly is to be convenient to dynamically adjust keepalive period adaptation different network environments.When the VAU ability changes with the form real-time report of keep-alive message.
Is how the example explanation realizes load balancing with a main VAU and two from VAU, sees also Fig. 3, comprising:
301, client (M_CU/PSS) is initiated order request to main VAU.
302, main VAU selects the lightest VAU of load according to the ability information that reports from VAU.

308, main VAU returns the Redirect response to client, carries the URL 2. from VAU among the location.
309,2. client removes to connect VAU again to 2. initiating order request from VAU.Under the identical situation of load, main VAU can select from VAU at random.
310, when client has new request to come again, handling process is similar.
Along with client's increase, program request increases, when 1. and 2. VAU transships, need main VAU that the transcoding service also is provided.But whole media transcoding network overload operation just has been described when main VAU also transships, and this just relates to the dilatation of media transcoding network.See also Fig. 4, illustrate how in dilatation, can not interrupt existing business.
401, client (M_CU/PSS) is initiated order request to main VAU.
402, main VAU judge from VAU 1. and 2. and main VAU all transship.
403, main VAU denial of service.
404, from VAU 3. the new order request of main VAU refusal adds one simultaneously.
Interpolation comprises from VAU process 3.:
405,3. send registration, the request of reaching the standard grade from VAU to main VAU.
406, will 3. be connected on the main VAU from VAU by the Remote configuration tool software, add information such as 3. user name of VAU, password, and allow its registration reach the standard grade.Main VAU to 3. feed back registration from VAU, the response of reaching the standard grade.
407,3. reach the standard grade success from VAU after, main VAU receives the new order request from client.
408, main VAU select load the lightest from VAU, promptly 3. from VAU.
