Dispatcher Based Dynamic Load Balancing on Web Server System

Use of Internet and frequent accesses of large amount of multimedia data are fast increasing the traffic of network. Performance evaluation and high availability of server are important factor to resolve this problem using various cluster based systems. There are several low-cost servers using the load sharing cluster system which are connected to high speed network, and apply load balancing technique between servers. It offers high computing power and high availability. The overall increase in traffic on the World Wide Web is augmenting user-perceived response times from popular Web sites, especially in conjunction with special events. A distributed website server can provide scalability and flexibility to manage with growing client demands. To improve the response time of the web server, the evident approach is to have multiple servers. Efficiency of a replicated web server system will depend on the way of distributed incoming requests among these replicas. A distributed Webserver architectures schedule client requests among the multiple server nodes in a usertransparent way that affects the scalability and availability. The aim of this paper is the development of a load balancing techniques on distributed Web-server systems.
