Multicast, Web service, Network performance, Scalability


The recent growth in the use of the World Wide Web in the Internet has increased the demand of objects stored in web servers. The load results in worse performance perceived by the users. Several approaches have been developed in order to improve content distribution of web objects. We have developed a web server using cyclic multicast. In this paper we present the implementation of a full system with client and server and evaluate the improvement in the performance. The utilisation of multicast provides a significant reduction in bandwidth, resources consumption in the network and in the server and prevents server collapse in extreme scenarios like massive access or flash-crowds.
