Software Fault Tolerance
نویسنده
چکیده
A fault-tolerant software unit is composed of N~2 diverse member units, usually developed by N separate teams, and an execution environment. The development process employs diversity requirements, communication protocols, and inter-team isolation rules to promote the greatest possible independence of team efforts and diversity among their products. The principal models, specification, building, evaluation, and system integration of fault-tolerant software are discussed, and goals for future work

An Overview of Software Fault Tolerant Computing
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 ...
متن کاملOn the Extension of Xception to Support Software Fault Models
Software faults are recognized as the major cause of system outages. The two possible approaches to overcome this problem are fault avoidance and fault tolerance. Quality assurance techniques fail to attain the zero defects mark, making fault tolerance vital to assure mission and business critical systems dependability. One major issue is the difficulty in the verification and validation of sof...
متن کاملDesign and Analysis of Transient Fault Tolerance for Multi Core Architecture
This paper describes the software approach of fault tolerance for shared memory multi core system using PLR.PLR uses a software-centric approach transient fault tolerance which ensuring a correct software execution. This scheme is used at user space level which does not necessitate changes to the original application.PLR create a set of redundant process per application process. In this scheme ...
متن کاملToward an Object-Oriented Approach to Software Fault Tolerance
Software fault tolerance is often necessary, but can itself be dangerously error-prone because of the additional effort that must be involved in the programming process. The additional redundancy may increase size and complexity and thus adversely affect software reliability. Object-oriented programming provides an appropriate framework for controlling complexity and enforcing reliability. Howe...
