Abstract:
We present an interaction model enabling data-source probes and action-based gauges to communicate using an intelligent event model known as ActEvents. ActEvents build on conventional event concepts by associating structural and semantic information with raw data, thereby allowing recipients to be able to dynamically understand the content of new kinds of events. Two submodels of ActEvents are proposed: SmartEvents, which are XML-structured events containing references to their syntactic and semantic models, and Gaugents, which are heavier but more flexible intelligent mobile software agents. This model is presented in light of DARPA's DASADA program, where ActEvents are used in a larger-scale subsystem, called KX, which supports continual validation of distributed, component-based systems. ActEvents are emitted by probes in this architecture, and propagated to gauges, where 'measurements' of the raw data associated with probes are made, thereby continually determining updated target-system properties. ActEvents are also proposed as solutions for a number of other applications, including a distributed collaborative virtual environment (CVE) known as CHIME.
