Abstract

The invention discloses a large-file multipoint distribution system, comprising a client, a center server, an upload server and a plurality of task processing servers; when files are required by the client to upload, the client transmits a file upload request to the center server, the center server determines the target task processing server for the client after receiving the upload request and the client uploads the files to be uploaded to the center server or the target task processing server by the upload server; and when the files are required by the client to download, the client transmits a file download request to the center server, the center server distributes a download task to the task processing server after receiving the download request, and the center server or the task processing server transmits the files required by the client to download to the client. The invention effectively avoids the problem that the center server has reduced performance or is halted because the files can be downloaded or uploaded from the center server only.

Description

technical field [0001] This application relates to the field of computer technology, in particular to a multi-point distribution system for large files. Background technique [0002] File distribution is one of the necessary support systems for the business and operation support systems of CDN service providers. The traditional file distribution method is to distribute files to multiple devices with a single device as the center, and the commonly used transmission protocols include HTTP protocol and FTP protocol. [0003] This traditional transmission method, when a large number of files need to be distributed, because all machines have to download or synchronize files from the central device, for example: there are 100 devices in the whole network that need to distribute files, and there are 100 files that need to be distributed. If the file is 100MB, then the pressure that the central device needs to hold is 100*100 concurrency, and lasts for 100MB / (total bandwidth / number...
