PROBLEM TO BE SOLVED: To provide a method and a system for timing synchronization between constituting elements in a network system. SOLUTION: The application of clock synchronization protocol for a plurality of synchronous domains comprises coping with asymmetric delay upon message transmission in double ring network topology employing a plurality of synchronous domains, the provision of a preliminary synchronous domain employing the plurality of synchronous domains, and the collection of informations with respect to the accuracy of a master clock employing the plurality of synchronous domains.
