Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

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.

Generic Broadcast

André Schiper, Fernando Pedone

Message ordering is a fundamental abstraction in distributed systems. However, usual ordering guarantees are purely syntactic'', that is, message semantics'' is not taken into consideration, despite the fact that in several cases semantic information a ...

The database state machine and group communication issues

Fernando Pedone

Distributed computing is reshaping the way people think about and do daily life activities. On-line ticket reservation, electronic commerce, and telebanking are examples of services that would be hardly imaginable without distributed computing. Nevertheles ...

The Database State Machine Approach

Rachid Guerraoui, André Schiper, Fernando Pedone

Database replication protocols have historically been built on top of distributed database systems, and have consequently been designed and implemented using distributed transactional mechanisms, such as atomic commitment. We present the database state mac ...

Optimistic Atomic Broadcast: A Pragmatic Viewpoint

André Schiper, Fernando Pedone

This paper presents the Optimistic Atomic Broadcast algorithm (OPT-ABcast) which exploits the spontaneous total order message reception property experienced in local area networks in order to allow fast delivery of messages. The OPT-ABcast algorithm is bas ...

Understanding Replication in Databases and Distributed Systems

André Schiper, Matthias Wiesmann, Fernando Pedone

Replication is an area of interest to both distributed systems and databases. The solutions developed from these two perspectives are conceptually similar but differ in many aspects: model, assumptions, mechanisms, guarantees provided, and implementation. ...

On Transaction Liveness in Replicated Databases

Rachid Guerraoui, Fernando Pedone

On Transaction Liveness in Replicated Databases F.Pedone and R.Guerraoui This paper makes a first attempt to give a precise characterisation of liveness in replicated database systems. We introduce the notion of liveness degrees, which express the expectat ...
