Exploration of Various Fault Tolerance Techniques
In the past few years, Mobile agent technology is one of the emerging, fastest growing and promising concepts for the development of applications. A mobile agent is composition of computer program that proceed autonomously for a user or application moving in the heterogeneous communication environment. This survey presents “pure fault tolerance technique “that enables a system to continue opera...
متن کاملTechniques of Software Fault Tolerance
Fault tolerance is the ability of a system to perform its function correctly even in the presence of internal faults. We should accept that, relying on software techniques for obtaining dependability means accepting some overhead in terms of increased size of code and reduced performance (or slower execution). N-version programming achieves redundancy through the use of multiple versions. Failu...
متن کاملEvolutionary Techniques for Fault Tolerance
Artificial evolution can integrate fault tolerance considerations into the automatic design process, producing inherently fault-tolerant designs without explicit redundant parts. Population dynamics can give rise to some level of fault tolerance ‘for free.’ Requirements for fault tolerance can also be incorporated into the fitness function. The practicalities of these methods are investigated, ...
متن کاملA Survey of Software Fault Tolerance Techniques
This report examines the state of the field of software fault tolerance. Terminology, techniques for building reliable systems, andfault tolerance are discussed. While a scientific consensus on the measurement of software reliability has not been reached, software systems are sufficiently pervasive that' 'software components" of larger systems must be reliable, since dependence is placed on the...
متن کاملA Survey of Software Fault Tolerance Techniques
The paper surveys various software fault tolerance techniques and methodologies. The techniques include traditional techniques: recovery blocks (RcB), n-version programming, n selfchecking Programming, retry blocks (RtB), n-copy programming and some new techniques: adaptive n-version systems, fuzzy voting, abstraction, parallel graph reduction, rejuvenation. The utility for each technique based...
