Embodiment Construction

[0010] The following is the realization process of this method, please refer to the instructions attached figure 1 :

[0011] Step S1, suppose Δ′T is the number of times that a certain page in the web proxy cache is accessed this time and the next time it is accessed. UserAvgΔ′T is calculated offline based on the web proxy log for each user who uses the cache to access the page The average value of Δ′T, and the UserAvgΔ′T of each user who uses the cache is calculated periodically according to the latest network proxy log;

[0012] Step S2: The user requests the page t, and judges whether the cache contains a copy of t and has not expired? If yes, go to step S7;

[0013] Step S3, delete the expired copy of t from the cache, and obtain a new copy of t from the network server;

[0014] Step S4, judge whether the remaining space in the cache is enough to store a new copy of t? If yes, go to step S6;

[0015] Step S5, the higher the weight of the page, the lower the priority, and the p...

Abstract

The method designs a network proxy caching replacement system by using the feature that user accesses network to implement network to implement network proxy caching service. It has following steps: S1, deltaT is supposed to be all amount numbers of visit between this visiting time and the next visiting time to a certain webpage in network proxy caching; S2, user requests webpage t, deciding if the copy of t is included in caching; S3, deleting the expired copy of t from caching, obtaining a new copy of t from network server; S4, deciding if the remaining space in the cache is enough to save the new copy of t; S5, replacing the lowest priority webpage; S6, saving the new copy of t in cache; S7, returning the copy to user; S8, renewing the weight of each webpage in cache according to weight calculation formula; S9, deciding if a certain time quantum is passed.

Description

Technical field [0001] The invention relates to the technical field of network communication, in particular to a network proxy cache replacement method that utilizes the access characteristics of network users. [0002] Web proxy caching refers to storing a copy of frequently used web pages on a web proxy server so that they can be accessed by local users more quickly. Through the network proxy cache, the access request sent by the local client to the remote website is rerouted to the cache server of the local network, and the cache server returns a copy of the requested webpage directly to the client browser. Web proxy caching is recognized as an effective method to alleviate the bottleneck of network services. However, the pages that can be cached in the web proxy are limited. When the cache space is insufficient to store a copy of the new webpage, one or some webpages in the cache need to be deleted according to the cache replacement method. The quality of the cache replacement...
