Abstract: Scalability is always an issue for multicast protocols. This paper
analyses and compares eight protocols for packet loss recovery in multicast
communications. The goal of our analysis is to emphasise which protocols
provide good recovery times without inducing too much extra traffic in the
network, which is the limiting factor for scalability. Assuming the same loss
rates on every link in the network, we make a statistical analysis to derive the
expected number of packet retransmissions and compare the performance of the
protocols. The results show great variations between protocols and provide
good insights for the design of new protocols.
