Graph Chatbot

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.

Total Order Broadcast and Multicast Algorithms: Taxonomy and Survey

André Schiper, Xavier Défago

Total order broadcast and multicast (also called atomic broadcast/multicast) is an important problem in distributed systems, especially with respect to fault-tolerance. In short, the primitive ensures that messages sent to a set of processes are delivered ...

Comparative performance analysis of ordering strategies in atomic broadcast algorithms

André Schiper, Xavier Défago

Comparative Performance Analysis of Ordering Strategies in Atomic Broadcast Algorithms Xavier Defago, Andre Schiper, Peter Urban In this paper, we present the results of a comparative analysis of Atomic Broadcast algorithms. The analysis was done by using ...

Appia vs. Cactus: Comparing Protocol Composition Frameworks

André Schiper, Sergio Mena, Xavier Cuvellier, Christophe Grégoire

The paper presents and compares Appia and Cactus, two frameworks for protocol composition. The comparison is based on the experience gained in implementing a fault-tolerant Atomic Broadcast service. The paper also gives preliminary performance results, and ...

Revisiting Token-based Atomic Broadcast Algorithms

André Schiper, Nils Richard Ekwall

Many atomic broadcast algorithms have been published in the last twenty years. The two main mechanisms used to tolerate failures (if we exclude synchronous systems and consider only crash failures) are unreliable failure detectors and group membership. Tok ...

Towards JMS-Compliant Group Communication

André Schiper, Matthias Wiesmann, Stefan Pleisch, Arnas Kupsys

Group communication provides communication primitives with various semantics and their use greatly simplifies the development of highly available services. However, despite tremendous advances in research and numerous prototypes, group communication stays ...

Robust TCP Connections for Fault Tolerant Computing

André Schiper, Nils Richard Ekwall

When processes on two different machines communicate, they most often do so using the TCP protocol. While TCP is appropriate for a wide range of applications, it has shortcomings in other application areas. One of these areas is fault tolerant distributed ...

Optimistic atomic broadcast: a pragmatic viewpoint

André Schiper, Fernando Pedone

Optimistic atomic broadcast: a pragmatic viewpoint F.Pedone and A.Schiper This paper presents the Optimistic Atomic Broadcast algorithm (OPT-ABcast) which exploits the spontaneous total-order property experienced in local-area networks in order to allow fa ...

Practical impact of group communication theory

André Schiper

Practical impact of group communication theory Andre Schiper Group communication is an important topic in fault-tolerant distributed applications. The paper summarizes the main contributions of practical importance that contributed to our current understan ...

Beyond 1-Safety and 2-Safety for Replicated Databases: Group-Safety

André Schiper, Matthias Wiesmann

In this paper, we study the safety guarantees of group communication-based database replication techniques. We show that there is a model mismatch between group communication and database, and because of this, classical group communication systems cannot b ...

Replicated Invocation

André Schiper, Stefan Pleisch, Arnas Kupsys

In today's systems, application are composed from various components that may be located on different machines. The components may have to collaborate in order to service a client request. More specifically, a client request to one component may trigger a ...
