Abstract

Embodiments of the present invention provide a method and device for updating cached content. The method includes: determining one or more cached contents in a current cache queue, obtaining a weight factor for each cached content; predicting the requested content within the current sliding time window , obtain one or more prediction contents; predict the weight factor of each prediction content in the current sliding time window according to the independent variable parameters related to the cache content; according to the weight factor of each prediction content in the current sliding time window, for Weighted summation is performed on each predicted content, and each predicted content is sorted according to the result of the weighted summation; one or more cached contents are updated according to the sorted predicted content. In the embodiment of the present invention, the network device obtains the predicted content through content prediction, and determines the weight factor of the predicted content through independent variable parameters related to the cached content, improves the hit rate of the updated cached content, and provides users with accurate caches Serve.

Description

technical field [0001] Embodiments of the present invention relate to the field of communications technologies, and in particular, to a method and device for updating cached content. Background technique [0002] Content Distribution Network (CDN) is a research hotspot of next-generation Internet architecture, which realizes content-centric data transmission through a distributed content caching mechanism. By introducing content into the network and pushing it to edge nodes closer to users, it can reduce the repeated transmission of redundant data in the network, reduce the bandwidth pressure on the backbone network, shorten the access distance and delay of users, and improve user experience and service quality. . [0003] Among them, the update strategy of cached content is one of the core research issues of content distribution networks. Due to the limited capacity of the cache server, it is necessary to design a strategy to periodically remove outdated, unpopular, low-va...
