Multicast is an efficient communication technique to save bandwidth
for group communication purposes. A number of protocols have been
proposed in the past to provide a reliable multicast service.
Briefly classified, they can be distinguished into sender-initiated,
receiver-initiated and tree-based approaches.
In this paper, an analytical bandwidth evaluation of generic
reliable multicast protocols is presented. Of particular importance
are new classes with aggregated acknowledgments. In contrast to
other approaches, these classes provide reliability not only in case
of message loss but also in case of node failures. Our analysis is
based on a realistic system model, including data packet and control
packet loss, asynchronous local clocks and imperfect scope-limited
local groups.
Our results show that hierarchical approaches are superior. They
provide higher throughput as well as lower bandwidth consumption.
Relating to protocols with aggregated acknowledgments, the analysis
shows only little additional bandwidth overhead and therefore high
throughput rates.
