A Prefetching Algorithm for Improving Web Cache Performance

C. Umapathi and J. Raja

Predictive Web pre fetching refers to the mechanism of deducing the forthcoming page accesses of a client based on its past accesses. Nowadays, improving the performance of the Web is a crucial requirement, since its popularity resulted in a large increase in the user perceived latency. In this study, we describe a Web pre fetching cum caching scheme that capitalizes on Web log mining methods. The proposed scheme achieves coordination between the two techniques (i.e., caching and pre fetching). Here the pre fetched documents are accommodated in a dedicated part of the cache, to avoid the drawback of incorrect replacement of requested documents. The requirements of the Web are taken into account, compared to the existing schemes for buffer management in database and operating systems. Experimental results indicate the superiority of the proposed method compared to the previous ones, in terms of improvement in cache performance.
