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; the traditional cache replacement algorithm Both do not consider the long-term access characteristics of data, do not balance the long-term access characteristics and burst access characteristics well, and do not take into account the changing trend of the content, resulting in a low cache hit rate

Embodiment Construction

[0051] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0052] like figure 1 As shown, the embodiment of the present invention provides a method for replacing data in the cache, including:

[0053] Step 11, obtaining the number of accesses to the accessed content within a preset time period;

[0054] Step 12, according to the number of visits, obtain the popularity value of the visited content;

[0055] Step 13, replacing the stored data in the cache according to the popularity value.

[0056] In this embodiment, by obtaining the number of visits to the accessed content within a preset time period; according to the number of visits, the heat value of the accessed content is obtained; according to the heat value, the data stored in the cache is processed Replacement: Use the popularity value as the basis fo...

Abstract

The present invention provides a method and device for replacing data in a cache, wherein the method includes: obtaining the number of visits to the accessed content within a preset time period; obtaining the popularity value of the accessed content according to the number of visits; The heat value is used to replace the stored data in the cache. The scheme of the present invention can more accurately predict the popularity of accessing content and improve the cache hit ratio.

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 ...
