A family of communication protocols, called quorum multicasts, is presented that provides efficient communication services for widely replicated data. Quorum multicasts are similar to ordinary multicasts, which deliver a message to a set of destinations. The protocols extend this model by allowing delivery to a subset of the destinations, selected according to distance or expected data currency. These protocols provide well-defined failure semantics, and can distinguish between communication failure and replica failure with high probability. The authors have evaluated their performance, taking measurements of communication latency and failure in the Internet. A simulation study of quorum multicasts showed that they provide low latency and require few messages. A second study that measured a test application running at several sites confirmed these results
