Abstract
A process to detect a failure of a constituent system () in a system of systems () consisting of a number of constituent systems () which exchange messages through a communications system (), in which every constituent system () has a global time with a known granularity g, and at least one constituent system creates, at periodic creation times () determined a priori from the progression of the global time, a time-triggered life-sign message, the time of transmission () of this life-sign message in the time-triggered communications system (), determined a priori from the progression of the global time, is synchronized with the creation time of this life-sign message, and the time of receipt () of this life-sign message, determined a priori from the progression of the global time, is synchronized with the timeout time point (), determined a priori from the progression of the global time, of a monitor () of this life-sign message monitoring the arrival of the life-sign message, wherein an error message is triggered at the timeout time point if no life-sign message has arrived at the expected time of receipt ().
