DNS-based load balancing in distributed Web-server systems

A cluster Web-server system can be deployed to support high request rates to Web application server (WAS) in Internet-banking. The domain name system (DNS) servers dispatch the client requests among the Web-servers through the URL-name to IP-address mapping mechanism. In this paper, we propose a cluster Web-server system arranged in the multiple logical ring connections, in which the DNS is integrated with an adaptive load balancing algorithm and evaluate the performance of the proposed distributed Web-server system. We show the performance measurements for the proposed system
