A synchronization strategy for a time-triggered multicluster real-time system
Hermann Kopetz, A. Kruger, Dietmar Millinger, Anton Schedl · 2002
The provision of a system-wide global time base with a good precision and sufficient accuracy is a fundamental prerequisite for the design of a multicluster distributed real-time system. We investigate the issues of clock synchronization in a multicluster system, where every node can have a different oscillator. Based on the parameter of a typical automotive distributed system we show that a precision and accuracy in the second range is achievable without undue effort.
