A Study on Web Caching based on Reference Characteristics of Web Objects

There are various web caching replacement algorithms related to reference characteristics of web objects were researched. They could be used in regard to user characteristics of caching environment. 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 will consider some approaches related to web caching with the reference characteristics of a web object and analyze how it improves performance of the response speed. The paper also covers the methods of usercharacteristics analysis and the methods of its application in web caching systems. We also review an algorithm with reduced heterogeneity of a web object. 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.
