Fault-Tolerant Genuine Atomic Multicast
- We present a very simple fault-tolerant atomic multicast algorithm. We suppose that we have disjoint process groups such that in each group we can realize the consensus. It is the case, for example, if, in each group, there is a majority of correct processes and if we dispose of a failure detecto

When birds die: Making population protocols fault-tolerant
- At vobis male sit, malae tenebrae Orci, quae omnia bella devoratis: tam bellum mihi passerem abstulistis. [6] Abstract. In the population protocol model introduced by Angluin et al. [2], a collection of agents, which are modelled by finite state machines, move around unpredictably and have pairwise

Fault-Tolerant Genuine Atomic Multicast To Multiple Groups
- We present a simple fault-tolerant algorithm that ensures total order delivery of messages sent to multiple groups of processes. It is based on one underlying block, namely, uniform consensus. Our algorithm is a multiple group "genuine and local " multicast algorithm in the sense that any proce

almost) all objects are universal in message passing systems
- Abstract. This paper shows that all shared atomic object types that can solve consensus among k>1 processes have the same weakest failure detector in a message passing system with process crash failures. In such a system, object types such as test-and-set, fetch-and-add, andqueue, known to have weak

From Crash-Stop to Permanent Omission: Automatic Transformation and Weakest Failure Detectors
- Abstract. This paper studies the impact of omission failures on asynchronous distributed systems with crash-stop failures. We provide two different transformations for algorithms, failure detectors, and problem specifications, one of which is weakest failure detector preserving. We prove that our tr

Revisiting failure detection and consensus in omission failure environments
- Abstract. It has recently been shown that fair exchange, a security problem in distributed systems, can be reduced to a fault tolerance problem, namely a special form of distributed consensus. The reduction uses the concept of security modules which reduce the type and nature of adversarial behavior

Mutual Exclusion in Asynchronous Systems with Failure Detectors
- This paper defines the fault-tolerant mutual exclusion problem in a message-passing asynchronous system and determines the weakest failure detector to solve the problem. This failure detector, which we call the trusting failure detector, and which we denote by , is strictly weaker than the pe

Shared Memory vs Message Passing
- This paper determines the computational strength of the shared memory abstraction (a register) emulated over a message passing system, and compares it with fundamental message passing abstractions like consensus and various forms of reliable broadcast.

Thrifty Generic Broadcast
- . We consider the problem of generic broadcast in asynchronous systems with crashes, a problem that was first studied in [12]. Roughly speaking, given a "conflict" relation on the set of messages, generic broadcast ensures that anytwo messages that conflict are delivered in the same order# messa

Stable leader election (extended abstract
- Abstract. We introduce the notion of stable leader election and derive several algorithms for this problem. Roughly speaking, a leader election algorithm is stable if it ensures that once a leader is elected, it remains the leader for as long as it does not crash and its links have been behaving wel
