Of Choices, Failures and Asynchrony: The Many Faces of Set Agreement

Rachid Guerraoui, Seth Gilbert, Dan Alistarh

Set agreement is a fundamental problem in distributed computing in which processes collectively choose a small subset of values from a larger set of proposals. The impossibility of fault-tolerant set agreement in asynchronous networks is one of the seminal ...

The impossibility of boosting distributed service resilience

Rachid Guerraoui

We study f -resilient services, which are guaranteed to operate as long as no more than f of the associated processes fail. We prove three theorems asserting the impossibility of boosting the resilience of such services. Our ﬁrst theorem allows any connect ...

In search of lost time

Martin Hutle

Dwork, Lynch, and Stockmeyer [3] and Lamport [4] showed that, in order to solve Consensus in a distributed system, it is sufficient that the system behaves well during a finite period of time. In sharp contrast, Chandra. Hadzilacos, and Toueg [6] proved th ...

An economic approach for scalable and highly-available distributed applications

Karl Aberer, Nicolas Bonvin

Service-oriented architecture (SOA) paradigm for orchestrating large-scale distributed applications offers significant cost savings by reusing existing services. However, the high irregularity of client requests and the distributed nature of the approach m ...

The Heard-Of model: computing in distributed systems with benign faults

André Schiper

Problems in fault-tolerant distributed computing have been studied in a variety of models. These models are structured around two central ideas: (1) degree of synchrony and failure model are two independent parameters that determine a particular type of sy ...

Relaxed Atomic Broadcast: State-Machine Replication Using Bounded Memory

André Schiper, Sergio Mena, Omid Shahmirzadi

Atomic broadcast is a useful abstraction for implementing fault-tolerant distributed applications such as state-machine replication. Although a number of algorithms solving atomic broadcast have been published, the problem of bounding the memory used by th ...

Abstractions for asynchronous distributed computing with malicious players

Marko Vukolic

In modern distributed systems, failures are the norm rather than the exception. In many cases, these failures are not benign. Settings such as the Internet might incur malicious (also called Byzantine or arbitrary) behavior and asynchrony. As a result, and ...

A formal approach to fault tolerant distributed consensus

Rachele Fuzzati

The term distributed Consensus denotes the problem of getting a certain number of processes, that could be far away from each other and that exchange messages through some communication means, to all agree on the same value. This problem has been proved im ...

On Collision-fast Atomic Broadcast

Rodrigo Malta Schmidt, Fernando Pedone

Atomic Broadcast, an important abstraction in dependable distributed computing, is usually implemented by many instances of the well-known consensus problem. Some asynchronous consensus algorithms achieve the optimal latency of two (message) steps but cann ...

Type-based event dissemination

Sébastien Bähni

With the explosion of broadband Internet connections in the late 80s, new types of applications, called distributed applications, came to light. These applications typically seek to provide a user with remote services that appear to that user as if they we ...
