Abstract

The use of commercial off the shelf (COTS) components in the development of dependable real-time systems, while effective in keeping systems affordable, also introduces vendor-driven upgrade problem. The dependable real-time computing community therefore needs to develop approaches that can introduce new hardware and software components into deployed systems safely, reliably and easily, in spite of the inevitable bugs in some of the new COTS components. This paper gives an informal review of the Simplex Architecture, which has been developed to support safe and reliable online upgrade of dependable computing systems.
