A Comparison of Sender-Initiated and Receiver-Initiated Reliable Multicast Protocols

Sender-initiated reliable multicast protocols based on the use of positive Acknowledgments (ACKs) can suffer performance degradation as the number of receivers increases. This degradation is due to the fact that the sender must bear much of the complexity associated with reliable data transfer (e.g., maintaining state information and timers for each of the receivers and responding to receivers' ACKs). A potential solution to this problem is to shift the burden of providing reliable data transfer to the receivers thus resulting in receiver-initiated multicast error control protocols based on the use of Negative Acknowledgments (NAKs).
