Method, system and device for content distribution, and media server

Abstract

The invention discloses a content distribution system. The content distribution system comprises a content distribution device and at least a media server, wherein the media server is loaded with a storage medium with different characteristics, or the storage medium with different characteristics is loaded between the media servers; and the content distribution device is used for selecting the storage medium for content according to the corresponding relationship between content attribute and the characteristics of the storage medium and distributing the content to the storage medium by the media server which is loaded with a storage medium. Correspondingly, the invention further discloses a content distribution method and a content distribution device. The content distribution system canreduce the cost of the storage medium in a CDN system and improve storage use ratio by distributing different types of contents to the storage medium with different attributes.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a content distribution method, a content distribution system, a content distribution device and a media server. Background technique [0002] The content delivery network (Content Delivery Network, CDN) is to add a new layer of network architecture to the existing IP network, and release the content to the "edge" of the network closest to the user, so that the user can obtain the required content nearby. At the same time, the content distribution network (hereinafter referred to as the CDN system) is also widely used in PC streaming media, Internet TV IPTV, mobile streaming media, video surveillance and other fields. Equal causes of unpleasant user experience when accessing streaming media content. In the CDN system, streaming media servers are deployed at the "edge" of the network to cache media content and provide services to users nearby. These streamin...

Problems solved by technology

[0006] The CDN system requires a large amount of storage, and the cost of the storage medium is also high. If the on-demand content and the recorded content are all stored on the same type of storage medium, the content of different application scenarios and different popularity will be stored in the solidified storage. In terms of type and storage configuration, the read and write performance of different storage media cannot be effectively utilized, nor can the read and write performance of different configurations of storage media be utilized, which is a waste of storage resources

Although media content fragmentation can solve the problem of media server and storage load balancing, there are still problems of low storage utilization and waste of storage resources when stored on the same type and configuration of storage media
