R.A. Conroy, H.A. Malec · OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · 1983
An architectural overview is provided of the fully distributed ITT 1240 system, emphasizing the following points: (1) The software architecture is fundamentally reliable because of the independence of functional modules and the rigor of interface mechanisms. (2) The hardware architecture is fundamentally reliable because the basic failure units are small and use LSI and VLSI components. (3) The architecture is inherently fault tolerant through the decoupling provided by message communication in the systems network. (4) Reliable performance is easily engineered to any level. (5) The field peformance has reached steady state system effectiveness predictions within three months of initial cutovers. 8 references.
