Multicast applications such as electronic news delivery and live sports Webcasting grow with the Internet. These Web-based services demand high quality of service in the competitive global Internet business. Resources such as bandwidth and buffer space need to be reserved for different sessions to provide such guaranteed services. We analyze the performance of three multicast resource allocation algorithms, namely equal allocation with reclaim on all links (EAR-ALL), EAR-OPT and EAR-LL-a simple algorithm that reclaims only on the last link as opposed to all possible links. Simulation results using packetized voice sources on the MBONE network are reported comparing the performance in terms of bandwidth, call blocking and new receiver joining probability.
