Problems solved by technology

[0005] In view of this, the present invention provides a method and device for determining a disk to solve the problem that when a disk is damaged, each user request for the damaged disk needs to perform a back-to-source operation, which will cause a large amount of back-to-source, and thus occupy More network resources cause network congestion

Abstract

The invention provides a magnetic disk determining method and device. According to the invention, if a history service magnetic disk stores a file corresponding to a request for acquiring the file, the history service magnetic disk is taken as a magnetic disk for responding to the request. At this moment, the service magnetic disk is not needed for tracing operation. Further, network resource occupancy is avoided and network jam is reduced.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, relates to a method and device for determining a magnetic disk. Background technique [0002] The content distribution network CDN server includes multiple disks, and a large number of video files are stored in these disks. Wherein, the CDN server is a video CDN server that provides services for video services. [0003] When one or more disks in these disks are damaged, the damaged disks need to be replaced with new disks, and the new disks are formatted and then used. Therefore, there is no video file on the new disk. When the CDN server locates the user request on the new disk according to the consistent hash algorithm, since there is no video file stored on the new disk, the CDN server will Designate the new disk to perform the back-to-source operation to obtain the video file corresponding to the user request. Wherein, back-to-source refers to downloading a video fi...
