Abstract. We study large-scale distributed cooperative systems that use optimistic replication. We represent a system as a graph of actions (operations) connected by edges that rei...
This paper addresses the problem of atomic multicasting messages in asynchronous distributed systems. Firstly, we give a characterization of the notion of genuine atomic multicast...
Weconsider the problemof generic broadcast in asynchronous systems with crashes, a problem that was rst studied in 12]. Roughly speaking, given a \con ict" relation on the set...
This paper describes a Secure INtrusion-Tolerant Replication Architecture1 (SINTRA) for coordination in asynchronous networks subject to Byzantine faults. SINTRA supplies a number...
Predictability is crucial in critical applications and systems. Therefore, we examine sources of uncertainty for each of the four phases that span a project lifecycle, from initial...
