We consider the problem of fault-tolerant agreement in a crash-prone synchronous system. We present a new randomized consensus algorithm that achieves optimal communication effici...
Three protocols for gossip-based failure detection services in large-scale heterogeneous clusters are analyzed and compared. The basic gossip protocol provides a means by which fai...
This paper proposes a concurrency model which integrates the asynchronous and event-driven nature of wireless etworks with higher-level abstractions that provide a more familiar p...
Formal methods can improve the development of systems with high quality requirements, since they usually o er a precise, nonambiguous speci cation language and allow rigorous veri ...
In this paper we study the suitability of the CORBA Event Service as a reliable message delivery mechanism. We first show that products built to the CORBA Event Service specificati...
