A Report on Software Functional Variability.

Abstract

Proposals are made for a software structure that provides a high degree of fault tolerance and is appropriate for a large, complex, real-time system such as an air traffic control system. Further proposals describe how the structure can be extended to allow software development work to be carried out in parallel with operational use of the system. A pilot system has been implemented on a Modular-One multiprocessor computer in order to test some of the concepts. An assessment of the work indicates that it has been only partly successful and some problems of a fundamental nature remain to be investigated. (Author)
