We determine what information about failures is necessary and sufficient to solve Consensus in asynchronous distributed systems subject to crash failures. In Chandra and Toueg [1996], it is shown that <italic>W</italic>, a failure detector that provides surprisingly little information about which processes have crashed, is sufficient to solve Consensus in(More)
Chandra and Toueg proposed a new approach to overcome the impossibility of reaching consensus in asynchronous message-passing systems subject to crash failures 6]. They augment the asynchronous message-passing system with a (possibly unreliable) failure detector. Informally , a failure detector provides some information about the processes that have crashed(More)
The principle of atomic commitment ordering, or guaranteeing serializability in a heterogeneous environment of multiple autonomous resource managers using atomic commitment.
Reliable concurrent processing of transactions in a database system is examined. Since serializability, the conventional concurrency control correctness criterion, is not adequate in the presence of common failures, another theory of correctness is proposed, involving the concepts of <italic>commit serializability, recoverability,</italic> and(More)
We investigate the problem of reaching Byzantine Agreement in arbitrary networks where both processors and communication links are subject to omission or stopping faults. For the case of deterministic, synchronous algorithms we give a necessary and sufficient condition relating the solvability of the problem to the connectivity of the network. In(More)
We determine the weakest failure detectors to solve several fundamental problems in distributed message-passing systems, for <i>all</i> environments -- i.e., regardless of the number and timing of crashes. The problems that we consider are: implementing an atomic register, solving consensus, solving quittable consensus (a variant of consensus in which(More)
