Fault tolerance – an ability of a system to cope with errors – is an important characteristic of safety-critical systems. However, the current approaches to software development often ignore the fault tolerance aspect. This results in an ad-hoc and often incorrect introduction of the fault tolerance mechanisms into system design. In this paper, we summarize the experience gained in the formal d...

This paper describes the OFTT (OLE Fault Tolerance Technology), a fault tolerance middleware toolkit running on the Microsoft Windows NT operating system that provides required fault tolerance for networked PCs in the context of industrial process monitoring and control applications. It is based on the Microsoft Component Object Model (COM) and consists of components that performs checkpoint-sa...

nowadays, robots account for most part of our lives in such a way that it is impossible for usto do many of affairs without them. increasingly, the application of robots is developing fastand their functions become more sensitive and complex. one of the important requirements ofrobot use is a reliable software operation. for enhancement of reliability, it is a necessity todesign the fault toler...

For the purpose of a clear discussion) this paper will introduce terms and paradigms used for fault tolerance. In this paper first the notions system, component, environment, design, structure and behaviour are presented. Then, the notions failure and fault are defined. After observing that designing a fault tolerant system is based on the use of redundaucy and fault hypotheses, the fundamental...

Fault tolerance is a major concern to guarantee availability of critical services as well as application execution. Traditional approaches for fault tolerance include checkpoint/restart or duplication. However it is also possible to anticipate failures and proactively take action before failures occur in order to minimize failure impact on the system and application execution. This document pre...

The AUTOSAR standard simplifies the complexity of automotive system design with its layered and modular software architecture. Currently, this standard has no support for fault-tolerance. Fault-tolerance will be required in the design of the future automotive systems to avoid catastrophic system failures and hazardous events. In this thesis, we present a study of fault-tolerance by means of sof...

In cloud computing the major problem area is fault tolerance. When many clients request the server simultaneously, server is overloaded which causes fault. In our approach the load balancing technique is used to avoid fault. There are various fault tolerance techniques in existing cloud computing. They are self healing, job migration, static load balancing and replication. There are some drawba...

The incorporation of fault tolerance techniques into robot systems improves the reliability but also increases the hardware and computational requirements in the overall system It is not always clear how to evaluate the merit or e ectiveness of di erent fault tolerance approaches for a given application In this paper we present a new set of performance criteria designed to measure and compare t...

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 coverage of the fault tolerance process are presented. Emphasis is given to the derivation of experimental...
