Abstract

The explosion of data traffic on the World Wide Web (WWW), web servers are
often experiencing overload from an increasing number of users accessing the servers at
the 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 the
Distributed Web System distribute the documents themselves. In this case the response
load shared but the document distribution process load added to the distributed web
system. In a Distributed Web Server location of document and replication process are very
important for load balancing. The traffic generated due to movements of documents at
runtime during load balance could also affect the performance of the DWS system. This
research work shows that minimizing such traffic in a DWS system. Several heuristic
document distribution schemes like distribution based on the request ratio and request
count to perform partial replication of site’s documents at selected server locations so that
load balancing is maintained. This system adds a new alternate web server to handle the
failure problem of the centralized web server.
