The explosion of data traffic on the World Wide Web (WWW), web servers areoften experiencing overload from an increasing number of users accessing the servers atthe same time. To address the performance and scalability problems of web servers,Distributed Web Systems are used to share the load in the web servers. The nodes in theDistributed Web System distribute the documents themselves. In this case the responseload shared but the document distribution process load added to the distributed websystem. In a Distributed Web Server location of document and replication process are veryimportant for load balancing. The traffic generated due to movements of documents atruntime during load balance could also affect the performance of the DWS system. Thisresearch work shows that minimizing such traffic in a DWS system. Several heuristicdocument distribution schemes like distribution based on the request ratio and requestcount to perform partial replication of site’s documents at selected server locations so thatload balancing is maintained. This system adds a new alternate web server to handle thefailure problem of the centralized web server.
