Abstract
A system includes a plurality of watchdog components. Each watchdog component is configured to receive a kick signal from its monitored function to determine whether the monitored function is active.

The respective token determines whether its respective watchdog component has timed out. Each watchdog component is further configured to generate a token responsive to the kick signal and further responsive to the respective token from all watchdog component that the each watchdog component is connected to. Each watchdog component is further configured to transmit the generated token to the all watchdog components that the each watchdog component is connected to.
