This paper presents the results of an in-depth survey [9] into the concept of a generic safety-critical network technology. We identify a need for an architecture that would provide a number of distributed services (such as membership, clock synchronization etc.) generically. Such a technology would not only exploit the benefits of software reuse, but would also eliminate a substantial part of the complexity (including the scope for error) from the design process. We first discuss the main results of this survey, namely the requisite properties of such a technology before giving a detailed definition of an arbitrary "safety-critical network". This section also considers the OSI reference model and gives reasons as to why it is not suitable for use in a hard real-time system. As exemplars, we describe a number of related networking technologies, namely, TTP, PROFIBUS and CAN. The paper is concluded with a discussion concerning the future direction of this research.
