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 softwarebased 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.
