Embodiment 1

[0034] See figure 1 , which is a flowchart of a method for adaptively copying hotspot files according to an embodiment of the present invention, which includes the following steps:

[0035] S101. Receive a file download request.

[0036] S102. Obtain index information of the file to be downloaded according to the file download request. The index information of the file can be searched according to the file name in the download request, and the index information mainly includes the size, number of copies and storage location of the file to be downloaded.

[0037] S103. Determine the storage disk of the downloaded file according to the index information. The storage disk can be a SATA disk (Serial ATA, serial port disk). It is worth noting that the files to be downloaded may be stored in multiple disks. At this time, the list of disks storing the files to be downloaded can be obtained according to the number of copies in the index information, and then according to the IO loa...

Abstract

An embodiment of the invention provides a hotspot file self-adaption copy method and system. The hotspot file self-adaption copy method comprises the following steps of receiving a file download request; obtaining index information of a to-be-downloaded file according to the document download request; determining a storage magnetic disk of a download file according to the index information; calculating file popular degrees of the to-be-downloaded file; judging whether the download file requires hotspot copy or not according to the file popular degrees of the download file; obtaining at least one buffering magnetic disk with the lowest load if the download file requires copy; copying a plurality of to-be-downloaded files into the buffering magnetic disk. The hotspot file self-adaption copy method can guarantee the file access rate of a server, reduces read-write pressure and read-write time delay of the magnetic disk.

Description

technical field [0001] The invention relates to the technical field of computer network data caching, in particular to a method and system for adaptive copying of hotspot files. Background technique [0002] CDN (Content Delivery Network, Content Distribution Network) is to store the content accessed by the user to the edge node closest to the user, so that the user can obtain the required content nearby. CDN acceleration is to push hotspot files to CDN edge nodes (Video Outside Center, that is, metropolitan area points), and directly serve users through edge nodes, so as to solve the Internet network congestion situation and improve the response speed of users accessing resources. [0003] At present, CDN edge nodes usually use memory as a cache, but for larger files, such as streaming media files, there are fewer files that can be cached in the memory, and the cache effect is not good. Moreover, when a file is accessed by a large number of users, it is easy to cause huge ...
