....on the Internet today. This growth has led to congested backbone links, overloaded Web servers and frustrated users. These problems will become more severe as new end user technologies such as cable modems are deployed. One solution that could help relieve these problems is object caching[18]. In this paper we present a trace driven simulation study of a Web proxy cache. Our goal in this study is to evaluate the effects of different workload characteristics on the replacement decisions made by the cache. The workload characteristics that we consider include object size, recency of ....

....clusters of machines to handle incoming requests. Network links can be upgraded to higher bandwidths to handle the increased volume of data traffic. However, these approaches are really only shortterm solutions. A more permanent solution to the scalability problems of the Web is file caching [18][27]. File caching is used to store documents 1 closer to the clients that request them. By doing this user latency, network loads and origin server loads can all be reduced. File caching can help eliminate network hotspots by reducing the volume of traffic to popular sites. File caching can also ....

....loads and origin server loads can all be reduced. File caching can help eliminate network hotspots by reducing the volume of traffic to popular sites. File caching can also dynamically adjust to eliminate flash crowds (i.e. temporarily popular sites) something that network upgrades cannot [27]. This paper presents a detailed workload characterization of a Web proxy server. We focus on identifying characteristics that we believe are important for proxy cache performance. We also examine the data set to determine the effects of higher client access speeds on the proxy workload. The main ....
