Scalability is always an issue for multicast protocols. This paper analyzes and compares protocols aimed at providing reliability to multicast communications in a scalable manner. Assuming the same loss rates on every link in the network, we make a probabilistic analysis of losses experienced at every participant to derive the expected number of retransmissions from which we obtain the overhead traffic caused by packet retransmissions and the average recovery time. Our work introduces a new multicast packet recovery protocol aimed at reducing packet loss correlation between receivers. This new protocol is compared to seven protocols taken from the literature. The results show that the new protocol has great performance and provides the shortest packet recovery times.
