Adaptive Distributed and Fault-Tolerant Systems

by Matti A. Hiltunen, Richard D. Schlichting - International Journal of Computer Systems Science and Engineering , 1995
"... An adaptive computing system is one that modifies its behavior based on changes in the environment. Since sites connected by a local-area network inherently have to deal with network congestion and the failure of other sites, distributed systems can be viewed as an important subclass of adaptive ..."

systems. As such, use of adaptive methods in this context has the same potential advantages of improved efficiency and structural simplicity as for adaptive systems in general. This paper describes a model for adaptive systems that can be applied in many scenarios arising in distributed and fault-tolerant

Fault Injection and Dependability Evaluation of Fault-Tolerant Systems

by Jean Arlat, Alain Costes, Yves Crouzet, Jean-claude Laprie, David Powell - IEEE Trans. Computers , 1993
"... Abstract- This paper describes a dependability evaluation method based on fault injection that establishes the link between the experimental evaluation of the fault tolerance process and the fault occurrence process. The main characteristics of a fault injection test sequence aimed at evaluating the ..."

Fault-Tolerant Holonic Manufacturing Systems

by Martyn Fletcher, S. Misbah Deen - Concurrency and Computation Practice & Experience , 2001
"... This paper presents a model of fault-tolerant Holonic Manufacturing Systems (HMS), where each holon is a knowledge-based agent capable of solving distributed problems by applying production/assembly and information management services. Our multi-agent architecture provides robustness and distribu ..."

A framework for reconfiguration-based fault-tolerance in distributed systems

by Stefano Porcarelli, Marco Castaldi, Felicita Di Giandomenico, Andrea Bondavalli, Paola Inverardi - IN DISTRIBUTED SYSTEMS,” ARCHITECTING DEPENDABLE SYSTEMS II , 2004
"... Nowadays, many critical services are provided by complex distributed systems which are the result of the reuse and integration of a large number of components. Given their multi-context nature, these components are, in general, not designed to achieve high dependability by themselves, thus their b ..."

, we focus on fault handling strategies, particularly on system’s reconfiguration. The paper describes a framework which provides fault tolerance of components based applications by detecting failures through monitoring and by recovering through system reconfiguration. The framework is based on Lira

Testing of Fault-Tolerant and Real-Time Distributed Systems via Protocol Fault Injection

by Scott Dawson, Farnam Jahanian, Todd Mitton, Teck-lee Tung - In Proceedings of the 26th International Symposium on Fault-Tolerant Computing (FTCS-26 , 1996
"... As software for distributed systems becomes more complex, ensuring that a system meets its prescribed specification is a growing challenge that confronts software developers. This is particularly important for distributed applications with strict dependability and timeliness constraints. This paper ..."
Abstract - Cited by 50 (7 self) - Add to MetaCart
reports on ORCHESTRA, a portable fault injection environment for testing implementations of distributed protocols. This tool is based on a simple yet powerful framework, called script-driven probing and fault injection, for the evaluation and validation of the fault-tolerance and timing characteristics

A FAULT-TOLERANCE LINGUISTIC STRUCTURE FOR DISTRIBUTED APPLICATIONS

by Vincenzo De Florio - UNIVERSITY OF LEUVEN, BELGIUM , 2000
"... The structures for the expression of fault-tolerance provisions into the application software are the central topic of this dissertation. Structuring techniques provide means to control complexity, the latter being a relevant factor for the introduction of design faults. This fact and the ever incr ..."
Abstract - Cited by 12 (9 self) - Add to MetaCart
increasing complexity of today's distributed software justify the need for simple, coherent, and effective structures for the expression of fault-tolerance in the application software. A first contribution of this dissertation is the definition of a base of structural attributes with which application

Security and Fault-Tolerance in Distributed Systems: An Actor-Based Approach

by Gul A. Agha, Reza Ziaei - IN PROCEEDINGS OF COMPUTER SECURITY, DEPENDABILITY AND ASSURANCE: FROM NEEDS TO SOLUTIONS , 1998
"... The inherent complexity of real-world distributed applications makes developing and maintaining software for these systems difficult and error-prone. We describe an actor-based meta-level model to address the complexity of distributed applications. Specifically, metalevel framework allow code implem ..."
