Real-time highly connected distributed systems

Abstract

The authors describe a development methodology applicable to real-time highly connected distributed systems in the domain of command and control. Models are developed for the system resource management activity and the application process in the domain. This methodology develops, as a basis for the domain, the interaction between the application and system model. This interaction is captured in an abstract process interface utilized by both application and system processes. The system model encapsulates solutions to problems with concurrent access to system data elements, fault tolerance, instrumentation, scheduling, and data distribution, reducing application program complexity. The application model utilizes system model elements by specification in the instantiated process interface from the elements of the abstract process interface. The surveillance application of the air defense system is used as an example of the application model. A prototype system implementation is used as the system model. >
