Abstract | |||||||||||||||||
| Enclosing a component within a software "wrapper" is a well-established way of adapting components for use in new environments. This paper presents an overview of an experimental evaluation of the use of a wrapper to protect against faults arising during the (simulated) operation of a practical and critical system; the specific context is a protective wrapper for an off-the-shelf software component at the heart of the control system of a steam raising boiler. Encouraged by the positive outcomes of this experimentation we seek to position protective wrappers as a basis for structuring the provision of fault tolerance in component-based open systems and networks. The paper addresses some key issues and developments relating wrappers to the provision of dependability in future computing systems. | |||||||||||||||||
