File caching method and device and electronic equipment

Abstract

The invention provides a file caching method and device and electronic equipment, and the method comprises the steps: determining a file information block corresponding to a first target file when a user accesses the first target file, and obtaining the current resource information; determining a file weight and calculating the file weight to obtain a first file score; updating the position of a first file information block corresponding to the first target file, determining a first information pointer to which the first file information block belongs so as to determine the highest-level storage medium for caching the first target file, and caching the first target file according to a caching strategy. By applying the method, the file score of the file is calculated according to each resource parameter, and the position of the file information block corresponding to the resource file in the file information list is updated, so that the resource file is cached according to the positionand the caching strategy. On the basis of the caching strategy, the resource files are cached more reasonably in combination with the file information list, so that the hit rate of the resource filesin a higher-level storage medium when a user accesses the resource files is increased.

Description

technical field [0001] The present invention relates to the technical field of data caching, in particular to a file caching method, device and electronic equipment. Background technique [0002] With the development of science and technology, the CDN (ContentDeliveryNetwork, content distribution network) system can forward the request to the edge node closest to the user when the user sends a resource request according to the network traffic, the distance of the edge node, the load situation and other information in real time , so that users can recently get the resource files they need. [0003] At present, when the CDN system processes the user's resource request, it responds to the user's resource request and at the same time caches the resource file requested by the user in multiple storage media of the local edge node. Since the cache space of each storage medium is different, As a result, each storage medium responds to resource files at different speeds. A storage ...

AI Technical Summary

Problems solved by technology

[0004] Due to the limited cache space of each storage medium, it is necessary to frequently add and delete resource files in each storage medium. The existing technology usually uses the least used replacement algorithm or the least recently used replacement algorithm to determine whether the storage medium needs to increase resources. Files or resource files are deleted, but the least replacement algorithm or the least recently used replacement algorithm is applied, and the cached resource files are only processed according to the latest clicks and access time of the resource files, and the storage space occupied by each resource file is not equal. , a large file can be equal to multiple small files, if the storage medium with a faster response speed caches all large files, the number of resource files cached in the storage medium will be reduced, reducing the storage time of each resource file. hit rate in medium
