A Novel Bandwidth-Efficient Multicasting Protocol for Wide Area Networks

摘要

In this paper we have proposed a practical approach for multicasting in wide area networks. It is a modification of the classical RPF approach. Though our approach is a modification of the RPF, it retains all the advantages of the RPF method and has an additional important advantage of efficient utilization of bandwidth by reducing the number of duplicate packets generated when compared to RPF. We have shown that the proposed approach offers better utilization of network bandwidth and router's memory when compared to the well known Distance Vector Multicast Routing Protocol.
