An Overview of Software Fault Tolerant Computing
نویسنده
چکیده
Fault-tolerance is the survival attribute of the real-time software system. The software should provide correct results in the face of various failures. A major technological concern for the coming years is the ever widening gap between the demand for high quality, robust software and its supply. Software fault tolerance is basically the design faults in the computer system. Its function is to prevent system accidents, and mask out faults if possible. A characteristic of the software fault tolerance techniques is that they can, in principle, be applied at any level in a software system: procedure, process, fault application program, or the whole system including the operating system. The continuous research works are done in the field of software fault tolerant computing to make error free software. But still it is difficult to make error free software due to complexity of the system. This paper presents a review fault tolerant computing, historic view of fault-tolerant computing, design fault tolerance, software fault tolerant techniques, software fault tolerance methods and concludes some thoughts on challenges of software fault tolerant computing.

The design of reliable and fault-free software is of a major concern for safety-critical real-time and distributed applications. The fault tolerant community addresses these problems through redundancy in hardware components and by diversity, using different software components. Diversity has been used for many years now as a computer defence mechanism to achieve an acceptable degree of fault-t...
