<p>PROBLEM TO BE SOLVED: To provide a communication network having dynamic synchronization, capable of changing the way of synchronization, when a clock is changed. SOLUTION: A communication network is provide with plural network nodes, which are respectively equipped with a synchronizing circuit for generating a global clock signal from a local clock signal formed by a clock generator, based on time when a massage is received, divider arrangement formed in the synchronizing circuit for diving the local clock signal, based on at least one division rate generated by scalar arrangement and a correcting period, and a comparator circuit for comparing the receiving time of the message with the reception time of the local clock signal, and for forming the correction period. Moreover, the synchronizing circuit is provided with a division control part for changing at least one division rate, when the correcting period exceeds a predefined first threshold.</p> |
