Abstract
Disclosed is a method for establishing a synchronization in a synchronous Ethernet system. Devices are classified according to the type of the devices, and a device having a highest class in the synchronous Ethernet system is detected, then it is determined if the device having the highest class is able to serve as the timing master. If so, the device having the highest class is able to serve as the timing master if only one such device is detected; otherwise, the timing master between devices having the highest class is selected through a collision algorithm.
Claims6
A method for selecting a timing master in a synchronous Ethernet system, the method comprising the steps of:
- assigning classes to a plurality of devices provided in the synchronous Ethernet system;
- detecting a device having a highest class and determining if the device having the highest class is able to serve as the timing master;
- determining if a number of the device having the highest class is one when it is determined that the device having the highest class is able to serve as the timing master;
- determining the device having the highest class as the timing master of the synchronous Ethernet system if only one device having the highest class is detected;
- and
- selecting the timing master of the synchronous Ethernet system from among devices having the highest class through a collision algorithm if there are at least two devices having the highest class.
