Unreliable Failure Detectors via Operational Semantics [chapter]

Uwe Nestmann, Rachele Fuzzati
2003 Lecture Notes in Computer Science  
In this paper, we provide a fresh look at failure detectors from the point of view of programming languages, more precisely using the formal tool of operational semantics.  ...  Using operational semantics, we prove formally that representations of failure detectors in the new model are equivalent to their original representations within the model used by Chandra and Toueg.  ...  Acknowledgments We very much thank André Schiper and Sam Toueg for enlightening discussions about failure detectors and, more generally, distributed algorithms, but they may not necessarily agree with  ...

failure detectors should provide are guaranteed.  ...  In the proposed method, we first construct a model for the NBAC protocol in a modular way by composing a behavior model for unreliable failure detector and a behavior model for distributed computing nodes  ...  Failure detectors are unreliable because they can suspect an operational node or not suspect a failed node.  ...

Failure Detection with Booting in Partially Synchronous Systems [chapter]

Josef Widder, Gérard Le Lann, Ulrich Schmid
2005 Lecture Notes in Computer Science  
Unreliable failure detectors are a well known means to enrich asynchronous distributed systems with time-free semantics that allow to solve consensus in the presence of crash failures.  ...  Implementing unreliable failure detectors requires a system that provides some synchrony, typically an upper bound on end-to-end message delays.  ...  A different -more abstract -approach was taken by Chandra and Toueg [5, 6] , who introduced the concept of unreliable failure detectors (FDs).  ...

Advances in the Design and Implementation of Group Communication Middleware [chapter]

Daniel Bünzli, Rachele Fuzzati, Sergio Mena, Uwe Nestmann, Olivier Rütti, André Schiper, Paweł T. Wojciechowski
2006 Lecture Notes in Computer Science  
Group communication is a programming abstraction that allows a distributed group of processes to provide a reliable service in spite of the possibility of failures within the group.  ...  The section proposes a fresh look at failure detectors by representing them via transition systems (as known from operational semantics), with the goal of bringing the definitions closer to our formal  ...  The concept of unreliable failure detectors has been introduced some time ago.  ...

On Process-Algebraic Proof Methods for Fault Tolerant Distributed Systems [chapter]

Morten Kühnrich, Uwe Nestmann
2009 Lecture Notes in Computer Science  
In settings with process failures, things get worse.  ...  The wrap code has to use perfect failure detectors since unreliable failure detectors may cause incorrect answers. For convenience, let R def = {a i,j,k , b i,j , c i } 1≤i,j,k≤n .  ...  Our own previous work [NFM03] has been in the context of much weaker imperfect (or: unreliable) failure detectors (♦S, as of [CT96] ).  ...

Towards a model-driven method for reliable applications

Vidar Slåtten, Frank Alexander Kraemer, Peter Herrmann
2010 Proceedings of the 2nd International Workshop on Software Engineering for Resilient Systems - SERENCE '10  
We present a model-driven method to incrementally introduce fault-tolerance mechanisms into application models that are initially developed with assumptions of ideal transmission semantics.  ...  This means that the transmission between partitions has the semantics described by the building block in Fig. 6 , with a send and receive operation.  ...  It shows that after a token is provided via input node pid, the authentication terminates either via ok or nok.  ...
