The book examines key programming techniques such as. The book is intended for practitioners and researchers who are concerned with the dependability of software systems. Phases in the fault tolerance implementation of a fault tolerance technique depends on the design, configuration and application of a distributed system. Fault tolerance techniques are used to predict these failures and take an appropriate action before failures actually occur. Following are the methods for preventing programmers from introducing faulty code during development.

A Survey of Software Fault Tolerance Techniques

However, cost and overhead information such as that described earlier in this chapter , performance analysis such as that described in [63] , design methodologies e. Software design faults are recognized as the current obstacle to successful dependable systems develop- ment [91]. Conventional development methods do not incorporate the processes and key activities required for effective development of dependable systems. To fill this need, Kaaniche, Blanquart, Laprie, and colleagues [91, 92] developed the dependability-explicit development model. The model provides guidelines emphasizing the key issues to be addressed during the main stages of dependable systems development [91, 92]. The dependability-e xpl ici t developme nt model provides lists of key activities related to system development phases.

Metrics details. Customizable software systems consist of a large number of different, critical, non-critical and interdependent configurations. Reliability and performance of configurable system depend on successful completion of communication or interactions among its configurations. Most of the time users of configurable systems very often use critical configurations than non-critical configurations. Failure of critical configurations will have severe impact on system reliability and performance. We can overcome this problem by identifying critical configurations that play a vital role, then provide a suitable fault tolerant candidate to each critical configuration.

Software Fault Tolerance: An Evaluation Abstract: In order to assess the effectiveness of software fault tolerance techniques for enhancing the reliability of practical systems, a major experimental project has been conducted at the University of Newcastle upon Tyne. Techniques were developed for, and applied to, a realistic implementation of a real-time system a naval command and control system. Reliability data were collected by operating this system in a simulated tactical environment for a variety of action scenarios. This paper provides an overview of the project and presents the results of three phases of experimentation.

Fault Tolerance-Challenges, Techniques and Implementation in Cloud Computing

Fault Tolerance pp Cite as. Fault tolerance techniques for coping with the occurrence and effects of anticipated hardware component failures are now well established and form a vital part of any reliable computing system. However, it is more unusual to find that strategies for fault tolerance have been included in a system for coping with design faults , although such strategies are becoming increasingly common in systems with high reliability requirements. For instance, applications in railway systems, nuclear reactor control and aircraft control are reported by Voges. Unable to display preview. Download preview PDF. Skip to main content.

Software fault tolerance is the ability of computer software to continue its normal operation despite the presence of system or hardware faults. Fault-tolerant software has the ability to satisfy requirements despite failures. The only thing constant is change. This is certainly more true of software systems than almost any phenomenon, [3] not all software change in the same way so software fault tolerance methods are designed to overcome execution errors by modifying variable values to create an acceptable program state. Fault tolerance must be a key consideration in the early stage of software development.
