Software Fault Tolerance

reportActive / Technical Report | Accession Number: ADA205180 | Open PDF

Abstract:

The main principles of software fault tolerance are presented and various schemes for achieving it are described, with emphasis being placed on the N-version programming and the recovery blocks schemes. The areas of research discussed include reliability modeling, version independence, and system simulation. A brief description of the use of software fault tolerance in aerospace applications is given and the important subject of cost-effectiveness is addressed. The potential benefits to Air Traffic Control systems are identified together with areas where further study and research are desirable.
