As distributed applications and services are getting popular now a days, Web servers play a central role in the telecommunications infrastructure. Cluster-based Web servers are increasingly adopted to host a variety of network-based services. So performance improvement of these servers is necessary. The cluster based architecture consists of front-end dispatcher and several back-end servers. Front end is responsible for request distribution. The back-end nodes are responsible for request

... ing. They should provide reliability, availability and efficient services. So performance improvement of these servers is necessary. Load balancing is one of the best efficient methods for performance improvement of cluster system. It is often desirable to isolate the performance of different classes of requests from each other. Our objective is to deliver better services to high priority request classes without over-sacrificing low priority classes. The main objective is to minimize the response time of requests that need intra cluster communication.
