Abstract
We analyze different retransmission schemes for Error Control in multicast protocols geared towards real-time, multimedia applications. We discuss why retransmission schemes are not inappropriate for such applications, but in fact can be quite effective. We present a quantitative analysis of such schemes, as well as simulation results, taking into account four different parameters (and not just the source throughput): 1) The probability of dropping a packet due to limited time for retransmissions, 2) the average time required to deliver a packet correctly to end receivers, 3) the number of times a packet will be retransmitted and 4) the cost to the network, in terms of packet duplications, of retransmitting a packet. We reach the counter-intuitive conclusion that the optimum scheme---in terms of all four of the above parameters---in the most general scenarios (where several hosts with widely varying propagation delays and `quality of connections' are participating in the session) is to...
