Description
Technical field
The present invention relates to Net Video System field, in particular it relates to a kind of streaming media server dynamical load distribution side
Method.
Background technology
As the mark of next generation internet application, stream media technology was obtaining development at full speed in recent years.In video
In networked systems applications, streaming media server carrying business it is mainly live, video recording, point multicast function, with the increasing of number of users
Add, the ability that convection media server provides service has very high requirement, and a high performance server is typically only supported several
Thousand concurrently connect, it is impossible to meet the access of a large number of users, server cluster and load are typically taken in order to solve this problem
Equilibrium meets user concurrent demand.
In server cluster, if be not monitored to the load state of each server, not based on load state pair
New client asks to carry out rational management, each unbalanced situation of server load will be produced, so that part server
Overload, and another part server free.The server of overload can refuse the new client request for distributing to it, and idle
Server can not be but serviced client.So that the efficiency of server cluster substantially reduces.So in current server collection
In group, load-balancing technique is all employed., please to the client newly to arrive by being monitored to the load state of each server
Ask and always reasonably dispatched according to server load.However, because this technology is not divided the request content of client
Analysis, it is simple to be scheduled by the load state of server, it is impossible to currently to be carried according to streaming media server well various
Service conditions carries out dynamic equalization distribution.
In summary, present inventor has found above-mentioned technology extremely during the present application technical scheme is realized
Following technical problem less be present：
(1) be it is simple be allocated according to server CPU in itself or total load, server can not be understood in real time
Load condition, cause each server actual loading uneven；(2) simply it is allocated, does not have according to server maximum number of connections
Have and carry out dynamically distributes according to the business weight of actual bearer；(3) just for a kind of business, the application to multiple business fusion comes
Saying needs more load equalizers, considerably increases cost.
The content of the invention
The invention provides a kind of streaming media server dynamical load distribution method, solve existing deficiency, this method
It can be analyzed based on the content of user terminal requests, it is more that live, program request that streaming media undertakes, video recording, alarm are pre-recorded etc.
Kind business carries out dynamic load leveling distribution, while can dynamically monitor the load condition of streaming media server, to reach
With the resource overhead of minimum, the purpose of the every business of completion of stability and high efficiency.
For achieving the above object, it is described this application provides a kind of streaming media server dynamical load distribution method
Method includes：
Step 1：User terminal asks streaming media server address to management server；
Step 2：Judge whether the sub- equipment of request has been opened, if having opened, the Streaming Media of the sub- equipment is opened in distribution
Server；If the sub- equipment is not turned on, step 3 is carried out；
Step 3：Judge whether the default equipment corresponding to the sub- equipment has been opened, if default equipment has been opened, not
More than maximum load, then the streaming media server of the equipment is opened in distribution, if default equipment is not turned on or more than maximum load,
Then carry out step 4；Distribution server refers to selecting a stream according to the principle of load balancing from more streaming media servers
Media server is to user terminal.
Step 4：The minimum streaming media server of a total load is found from current online streaming media server to be divided
Match somebody with somebody；The total load of streaming media server=video recording number * first loads the weighting+loads of program request number * second weighting+live number
The load weightings of mesh * the 3rd.
Wherein, it is the characteristics of this method：Load balancing dynamic allocation scheme is employed, management server obtains stream in real time
The load information of media；Can the streaming media live, program request, the video recording multiple business that undertake carry out dynamic load leveling distribution；
The total load of streaming media server=video recording number * loads weighting+program request number * loads weighting+live number * load weightings；
In units of headend equipment, management server using equipment state and priority facility as streaming media server load distribution because
Element carries out dynamic equalization.
Further, methods described is applied in Net Video System, and Net Video System includes headend equipment, user's end
End, management server, more streaming media servers.
Further, streaming media server has live, program request and video recording business, and management server is used to monitor each stream
The load condition of media server, responds the service request of user terminal, and the minimum streaming media server of scheduling present load supplies
Service terminal uses.
Further, management server timing obtains load information to streaming media server, and load information includes：
(1) the sub- number of devices MaxDevNum that Streaming Media can be supported；
(2) the sub- number of devices OpenedDevNum having already turned on；
(3) the affiliated cluster ID number MSCSID of streaming media server；
(4) record a video number RecordNum；
(5) video recording weighting RecordWeight；
(6) program request number VodNum；
(7) program request weighting VodWeight；
(8) live number LiveNum；
(9) live weighting Live Weight；
(10) list of devices set.
Further, list of devices includes device numbering, equipment state, priority facility.
Further, equipment state 0 represents to close, and 1 represents to open.
Further, priority facility successively decreases from Level1 to Level9.
Further, for asking demand (telecommunication) service, directly distribution load is minimum and the streaming media server of still full load is given
User terminal.
When further, for the live business with video recording of user terminal requests, management server arrives according to timing acquisition
Equipment and load information carry out load judgment.
Further, if the equipment is opened by a streaming media server, the Streaming Media is distributed to user terminal；Such as
The fruit equipment is not switched on, and equipment is assigned to the minimum streaming media server of total load by management server, and by streaming media service
Device address returns to user terminal.
One or more technical schemes that the application provides, have at least the following technical effects or advantages：
The present invention provides one kind and realizes multiple business application load dynamic allocation method for Streaming Media, and this method can be right
Live, program request that Streaming Media undertakes, video recording multiple business carry out dynamic load leveling distribution, while can dynamically monitor stream matchmaker
The load condition of body server, to reach with the resource overhead of minimum, the technique effect of the every business of completion of stability and high efficiency.
Brief description of the drawings
Accompanying drawing described herein is used for providing further understanding the embodiment of the present invention, forms one of the application
Point, do not form the restriction to the embodiment of the present invention；
