....selection, Web I. INTRODUCTION Distributed systems rely on replicated objects and services to improve performance and reliability. For example, popular World Wide Web sites are often replicated at multiple locations, and systems are being designed to share cached objects across the Internet [1][2][3] 4] When objects are replicated or cached on multiple servers, the client would like to select a server that offers fast response time. However, fluctuations in network congestion and server load make it difficult to predict response times, especially during busy times of day when network load ....
