Prioritizing Documents and Applying Hybrid Caching Strategy for Network Latency Reduction

Abstract

World Wide Web is the fastest growing applications on the Internet. The exponential growth of its traffic volume causes a great demand for bandwidth and server capacity, which in turn results in acute problems including network congestion, high bandwidth demands, high latency for extracting documents, and server overloading. Web caching has been recognized as an attractive solution to reduce network traffic and all the associated problems. By storing frequently accessed contents at a location closer to the user, a great deal of latency and unpredictable delay in the Internet can be eliminated. This paper proposes a hybrid-caching scheme where a certain number of caches cooperate at every level of a caching hierarchy using distributed caching to reduce latency for popular documents
