In video on-demand system, the video data volume is very big, no matter is storage or Network Transmission, and is all very big to the consumption of system resource (such as disk volume, memory size, the network bandwidth, processor hardware etc.).And video request program is different from traditional internet, applications, is characterized in high bandwidth consumption, delay sensitive etc.Face this situation, if we can make video on-demand system under the existing resources condition by the program request Access Control Policy, can provide the more service ability, and can satisfy the demand of program request quality of services for users, can produce great economic worth and social benefit undoubtedly.
The common video on-demand system of TV and Radio Service is the shared memory system, and this system mainly passes through disk array/network storage medium, streaming media server cluster, broadcasting and television network and user's formations such as terminal set top box.In conventional art, the Access Control Policy that said system adopted is: as long as disk array/network storage has enough bandwidth to provide service to the user, so just allow the access request of terminal set top box; If the bandwidth deficiency, then refusal inserts request.This mode is easy to realize when the user terminal requests rate is low good effect to be arranged.But when if the user terminal requests rate is higher, video on-demand system then can not be realized optimized operation, the video request program inefficiency.And in the reality operation, this access control mode is lower to usage factor of system resource, is unfavorable for the increment of economic benefit.
Summary of the invention
Technical problem to be solved by this invention is: a kind of video request program connection control method is provided, overcomes the deficiency of conventional art, improve video request program efficient and resource utilization ratio under the situation that does not increase hardware cost.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of video request program connection control method may further comprise the steps:
A. but the video to all program requests in the video on-demand system is numbered, and guarantees that each video has unique number;
B. each video after the numbering is set priority;
C. create video request program priority query according to the priority of the video of user terminal program request;
D. when the user terminal requests video request program, whether at first judge the required bandwidth of video of its request program request and bandwidth sum that system has used less than overall system bandwidth, if, execution in step e then, otherwise execution in step f;
E. allow the access request of this user terminal, and the video numbering of its request is inserted in the video request program priority query by queue sequence, finish;
Whether the priority of video of f. judging this user terminal requests program request greater than the minimum priority in the video request program priority query, if, execution in step g then, otherwise execution in step h;
G. disconnect the video request program of video request program priority query medium priority minimum and remove its corresponding numbering, the numbering of the video of this user terminal requests program request is inserted in the video request program priority query by queue sequence, allow the access request of this user terminal, finish;
H. refuse the access request of this user terminal.
Further, among the step b, price, the code check by the assessment video, playing duration, terminal use's VIP rank is comprehensively weighed the priority of video: price is high more, and priority is high more; Code check is big more, and priority is low more; Playing duration is big more, and priority is low more; User VIP rank is high more, and priority is high more.
Further, among the step c, create video request program priority query from height to low order or from low paramount order according to the priority of the video of user terminal program request.
The invention has the beneficial effects as follows: do not increasing under the system hardware condition of cost,, improving video request program efficient and resource utilization ratio, helping the economic benefit increment of operator for more user terminal provides video-on-demand service.
Description of drawings
Fig. 1 is the video request program connection control method flow chart among the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
The present invention makes the problem that video request program efficient is low, resource utilization ratio is low in order to overcome video request program Access Control Policy in the conventional art, disclose a kind of video request program connection control method, under the situation that does not increase hardware cost, improved video request program efficient and resource utilization ratio.The main points of this scheme are: by video is carried out exclusive number, and setting priority, create video request program priority query according to the priority of the video of user's program request then, when user terminal carries out the video request program request, need to judge whether current system remaining bandwidth is enough, if enough then allow directly access, if remaining bandwidth deficiency, then continue to judge, the priority of minimum in video priority and the video request program priority query of request is compared, if the former height, then disconnect the minimum video request program of video request program priority query medium priority, and remove its video numbering, and allow the access request of user terminal, if the former is low, the then access request of refusing user's terminal.
As shown in Figure 1, on concrete enforcement, the present invention adopts following steps to finish:
1. but the video to all program requests in the video on-demand system is numbered, and guarantees that each video has unique number;
2. each video after the numbering is set priority, price that can be by the assessment video, code check, playing duration, terminal use's VIP rank is comprehensively weighed the priority of video: price is high more, and priority is high more; Code check is big more, and priority is low more; Playing duration is big more, and priority is low more; User VIP rank is high more, and priority is high more;
3. create video request program priority query according to the priority of the video of user terminal program request: after system start-up, priority according to the video of user terminal program request is created video request program priority query (during initial condition from height to low order or from low paramount order, owing to also there is not user terminal requests to insert, therefore video request program priority query is empty), when user terminal success access media server, system is added to the numbering of the video of its request in the video request program priority query, and queue sequence is arranged according to priority orders;
4. when new user terminal requests video request program, judge at first whether the last bandwidth of current system satisfies the demands, if the required bandwidth of video of request program request is less than the last bandwidth of system, then allow this user terminal directly to insert, and the numbering of the video of its request is inserted in the video request program priority query according to priority orders, illustrate that this video is by program request; If the required bandwidth of video of request program request is greater than the last bandwidth of system, illustrate that current system bandwidth is not enough for this video of program request, need this moment the priority of this video and the lowest priority in the video request program priority query are compared, if the former is lower, then the refusing user's terminal pins is to the order request of this video; If the former is higher, then disconnect the video request program of video request program priority query medium priority minimum, from video request program priority query, remove the video numbering of priority minimum, the numbering of the video of this user terminal requests program request is inserted in the video request program priority query by queue sequence, allows the access request of this user terminal.
Above-mentioned means can adopt writes software program and finishes on the basis of original system hardware, do not increase any hardware cost, and also is easy to those skilled in the art realize.
