In this paper, the authors have proposed a practical approach for broadcasting in wide area networks. The concept of pseudo-diameter, an important parameter in the DVR data structure unused by the RPF method has been applied to prune the flow of packets in order to achieve reduction in the number of the duplicate packets generated during broadcasting. Performance comparison with the classical RPF method shows that the proposed method generates fewer duplicate packets and hence it is more bandwidth efficient. They have further enhanced the idea by incorporating a new pruning scheme to further reduce the number of duplicate packets; thereby even offering better QOS from the viewpoint of better bandwidth utilization.
