Method and device for replacing data in cache

Abstract

The invention provides a method and a device for replacing data in a cache. The method comprises the following steps of acquiring visit times of visited contents within a preset time period; acquiring heat value of the visited contents according to the visit times; and replacing the data stored in the cache according to the heat value. By the scheme, heat of the visited contents can be accurately predicted, and the hit rate of the cache is increased.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for replacing data in a cache. Background technique [0002] With the rapid development of the Internet (Internet), more and more people obtain rich information resources through the Internet. However, the sharp increase in the number of users will inevitably bring about problems such as increased load on the web server, increased response delay from the client, and congestion on the backbone network. Especially in recent years, Internet streaming media applications such as video-on-demand, distance education and e-commerce have become increasingly widespread, making these problems more serious. [0003] The traditional way to solve these problems is to continuously upgrade the network server and increase the network access bandwidth. However, this traditional method cannot fundamentally solve the problem, because, usually, the upgrade speed of the server is lower ...

AI Technical Summary

Problems solved by technology

[0007] Usually, the performance index to measure the pros and cons of a cache replacement strategy mainly includes the cache hit rate, also referred to as the hit rate for short. The so-called cache hit rate refers to the ratio of the number of cache page hits to the total number of user requests;
