Probabilistic bounds on message delivery for the totem single-ring protocol
Moser, Melliar-Smith · 1994
For fault-tolerant real-time distributed systems, the probability that a message is not delivered within its real-time deadline must be small enough that it does not adversely affect system reliability. The authors investigate the delivery of messages for the totem protocol, a reliable ordered broadcast protocol that the authors have developed for fault-tolerant distributed systems with physical broadcasts over a local-area network. The total order on broadcast messages, constructed by the totem protocol, supports the maintenance of consistency of replicated information as, for example, in a replicated database. The authors present a methodology for determining the probability of satisfying bounds on the latency from message origination to ordered delivery in the presence of communication faults.>
