The effect of testing on reliability of fault-tolerant software

Popov, P. T. and Littlewood, B. (2004). The effect of testing on reliability of fault-tolerant software. Paper presented at the 2004 International Conference on dependable systems and networks, 28 June - 1 July 2004, Florence, Italy.

Abstract

Previous models have investigated the impact upondiversity - and hence upon the reliability of fault-tolerantsoftware built from 'diverse' versions - of the variation in'difficulty' of demands over the demand space. Thesemodels are essentially static, taking a single snapshotview of the system. In this paper we consider ageneralisation in which the individual versions areallowed to evolve - and their reliability to grow - throughdebugging. In particular, we examine the trade-off thatoccurs in testing between, on the one hand, the increasingreliability of individual versions, and on the other handthe possible diminution of diversity.
