Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] In the embodiment of the present invention, by setting up a scheduling server in the video-on-demand system, a node with sufficient resources in the video-on-demand system is selected by the scheduling server as a candidate seed node, and a seed node needs to be added according to the program-on-demand effect in the video-on-demand system. The program of the node is allocated to the candidate seed node, and the candidate seed node actively caches the program to improve the service quality and reliability of the video-on-demand system.

Abstract

The invention is suitable for video-on-demand systems and provides a video-on-demand system with a data cache method thereof and a dispatching server. The method includes the following steps: selecting candidate seed nodes from the user nodes, and storing the candidate seed nodes information; generating an active cache task according to the stored candidate seed nodes and the programs in the video-on-demand system; distributing the active cache task to the corresponding candidate seed nodes in order to lead the candidate seed nodes to carry out program cache. The embodiment of the invention has the advantages of improving the service quality and reliability of the video-on-demand system by distributing the programs waiting for the active cache to the candidate seed nodes and assigning the candidate seed nodes to cache the programs actively.

Description

technical field [0001] The invention belongs to the field of video-on-demand, and in particular relates to a video-on-demand system, a data cache method and a scheduling server thereof. Background technique [0002] The video-on-demand system (Video-on-Demand, VOD) is widely used in fields such as video broadcasting, video monitoring and distance education because it allows information demanders to select desired information at any time. Existing video-on-demand systems generally adopt a client / server (C / S) model, wherein the programs are stored in the server, and the client sends a program request to the server, and the server transmits the requested program to the client and plays it by the client. Since the data processed by the VOD system is generally a program, and the program usually takes up a lot of disk space, high transmission bandwidth, and takes up a lot of processor resources during processing, the use of the C / S mode is likely to cause a bottleneck problem on t...
