In the rest of the paper we will describe Top-10 prefetching in more detail and present performance results based on trace-driven simulation. In section 2 we outline client-proxy-server framework on which Top-10 prefetching can be applied. In section 3 we use trace-driven simulation based on server traces from five different universities, research institutes, and Internet providers to quantify the performance of prefetching documents using Top-10. The performance results are very encouraging suggesting that when using Top-10, web proxies are able to successfully prefetch up to 60% of their future requests, with a corresponding increase in network traffic only in the order of 20%. To put it simply, more than half of the future requests can be predicted and prefetched. Section 4 surveys related work, and places Top-10 in the appropriate context. Section 5 discusses various aspects of Top-10. Finally, section 6 summarizes and concludes the paper.
