Design and performance analysis of the web caching algorithm for performance improvement of the response speed

Abstract

Until now, various web caching replacement algorithms related to this were researched. An aggravation of web object heterogeneity more frequently generates a replacement of a web object, but cannot reflect enough all kinds of characteristics of web object in these traditional replacement techniques. Especially size heterogeneity of an object has an influence on performance of a web caching seriously. Therefore, a study on web caching algorithm with size heterogeneity of an object is required. In this study, we proposed a web object replacement algorithm with heterogeneity of a web object for performance improvement of the response speed. The algorithm is designed with a divided scope that considered size reference characteristic and reduced size heterogeneity on web object. The performance of the algorithm is analyzed with an experiment. With the experiments results, the algorithm is compared with previous replacement algorithms, and its performance is confirmed with 10%-20% elevation of object-hit ratio and an improvement of response speed. © Springer-Verlag Berlin Heidelberg 2007.
