Content distribution network scheduling method and system, and local object management server

Abstract

The invention discloses a content distribution network scheduling method and system, and a local object management server, and relates to the technical field of triple network integration. The present invention establishes a set of object description files for the same content. When different types of terminals access the same content, although the actually accessed video files are different, the content identifiers in the access URL are the same, and they all point to the same set of object description files. Therefore, this application It is only necessary to maintain the content of the object description file collection, and there is no need to maintain the entity file association relationship; moreover, the same content only needs to be injected once, if the sub-file corresponding to this type of terminal cannot be found in the object description file collection, you can The content file is transcoded to obtain the corresponding sub-file, thereby realizing the sharing of the same content, reducing the number of times of pulling up the stream, and saving network bandwidth.

Description

technical field [0001] The invention relates to the technical field of triple network integration, in particular to a content distribution network scheduling method and system, and a local object management server. Background technique [0002] Content Delivery Network (CDN for short), by adding a new layer of network architecture to the existing IP bearer network, sends content such as video, audio, and web pages to the "edge" of the network closest to the user, enabling users to The required content can be obtained nearby, thereby optimizing the network traffic conditions and improving the response speed of users visiting the website. CDN can solve the problem of slow user access response speed caused by low backbone network bandwidth, large user access volume, and uneven network distribution. [0003] The objects scheduled by the existing CDN system are individual physical files, and what users request is also individual physical files. The entire CDN architecture is des...
