ABSTRACT:
A system may include a communication medium, a master node, and a slave node. The master node may send several sets of synchronization messages on the communication medium. Each set of synchronization messages includes several synchronization messages. The slave node may receive each set of synchronization messages and to select a synchronization message having an optimal delay from each set of synchronization messages. The slave node may calculate a correction for a slave clock included in the slave node in response to timing information associated with the synchronization message having the optimal delay in each set. The slave node may not calculate a correction for the slave clock in response to timing information associated with at least some of the synchronization messages in each set. The communication medium may convey at least one synchronization message within each of the sets with a minimum delay.
