Distributed monitoring for component-based traffic management systems

Embedded software in the field of traffic management and control systems has an increasing demand on availability. Typically in case of a failure, hardware circuit watchdogs reset the whole system targeting the goal, that after some acceptable time the system is up and the applications are running correctly again. Also software-based monitoring solutions implementing standard patterns like the Watchdog Pattern, the Safety Executive Pattern or extensions to it might be applied. As these patterns target monitoring of components on a single node, extensions for monitoring distributed components using WBEM-technology for distributed monitoring will be shown. For a proof-of-concept implementation the Windows Management Instrumentation has been applied.
