AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Keywords: distributed systems, fault-tolerance, consensus, efficiency, synchronous system, asynchronous system, failure detector. We compare, in terms of solvability and efficiency, the synchronous model, noted S_S, with the asynchronous model augmented wi ...
This paper presents the abstraction of lazy consensus and argues for its use as an effective component for building distributed agreement protocols in practical asynchronous systems where processes and links can crash and recover. Lazy consensus looks like ...
Distributed computing is one of the major trends in the computer industry. As systems become more distributed, they also become more complex and have to deal with new kinds of problems, such as partial crashes and link failures. While many middleware archi ...
Informally, an indulgent algorithm is a distributed algorithm that tolerates unreliable failure detection: the algorithm is indulgent towards its failure detector. This paper formally characterizes such algorithms and states some of their interesting featu ...
In [CT96], [FRT99], and [SM95], respectively, it was stated that the weakest failure detector for any of non-blocking atomic commit, terminating reliable broadcast and leader election, is the Perfect failure detector P. This paper presents a counter exampl ...
A three-tier application is organized as three layers: human users interact with front-end clients (e.g browsers); middle-tier application servers (e.g. Web servers) contain the application's business logic, and perform transactions against back-end databa ...
This paper presents type-based publish/subscribe, a new variant of the publish/subscribe paradigm. Producers publish message objects on a communication bus, and consumers subscribe to the bus by specifying the types of the objects they are interested in. M ...
An e-Transaction is one that executes exactly-once despite failures. This paper describes a distributed protocol that implements the abstraction of e-Transactionsin three-tier architectures. Three-tier architectures are typically Internet-oriented architec ...
A lot of activity is currently going on to replace the SNMP management architecture with a solution better suited to managing modern IP networks and systems. New candidates include Management by delegation, active networks, and Web-based management. In thi ...
Publish/subscribe is considered one of the most important interaction styles for the explosive market of enterprise application integration. Producers publish information on a software bus and consumers subscribe to the information they want to receive fro ...
