A ‘substrate’ for dynamically defined behavior in high assurance, embedded, real-time systems



This paper proposes development of a standard ‘substrate’ for dynamically defined behavior that supports the run-time definition of completely new and previously unanticipated behavior. This stands in contrast to most embedded, hard real-time systems that only support switching between previously defined states and alternatives. The proposal supports the ability to define new behaviors both as end user defined scenarios (which have a run-time representation), and as cross cutting strategies and policies (in an aspect-oriented sense). In the context of systems that learn, it can be used to exchange experience (learned strategies and optimized scenarios). In the context of command and control systems it can be used to issue ‘orders’ corresponding to radical, and unexpected changes in mission. The approach will initially be targeted to a networked Java platform for high assurance, embedded, hard real-time systems. Support for an explicit state based run-time representation allows us to easily analyze system behavior using light weight formal methods such as model checkers. The incremental specification of new behavior allows us to explore similar incremental approaches to analysis. Potential DARPA applications include the use of the platform as a mission computer on an unmanned combat vehicle or, more generally, as a node in a highly adaptable next generation tactical Internet.
