Performance evaluation of a load balancing routing algorithm for clustered multiple cache servers

摘要

The explosive growth of World Wide Web us- age is causing a number of performance problems, including slow response times, network congestion, the denial of service. Web site that has a huge number of accesses and requires high quality of services, such as a site offering hosting services, or content de- livery services, usually uses a cache server to reduce the load on the original server offering the original content. To increase the throughput of the caching process and to improve service avail- ability, multiple cache servers are often positioned in front of the original server.
