Abstract
An embodiment of the invention includes a method and network for clock synchronization within a time triggered network using time slots, having at least two clusters. The clusters are connected to a coupling unit that includes a clock alignment control logic. The clock alignment control logic includes a coupling unit clock source which is more accurate than the node clock source. The accuracy of the coupling unit clock source is due to the coupling unit clock source including an oscillator crystal with smaller guaranteed deviations than the guaranteed deviations of the node clock source and/or the coupling unit clock source receiving a clock signal from an external clock device or from a GPS device. The method includes using a rate correction for offset correction.
