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 may 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

The embodiment of the present invention proposes a hot file self-adaptive copy method and system. The method includes: receiving a file download request; obtaining index information of the file to be downloaded according to the file download request; determining the storage disk of the downloaded file according to the index information; The file heat of the downloaded file; according to the file heat of the file to be downloaded, it is judged whether the file to be downloaded needs a hot copy; if copying is required, at least one buffer disk with the lowest load is obtained; multiple copies of the file to be downloaded are copied to the obtained buffer disk. The invention can ensure the file access rate of the server, reduce the reading and writing pressure, and reduce the delay of disk reading and writing.

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 hot files to the CDN edge node (Video Outside Center, that is, metro point), and directly serve users through the edge node, 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 reading pre...
