1. A method of synchronizing a communication network, the method comprising:
obtaining, by a network management system, a quality parameter of at least two or more synchronization sources connected to communication nodes in the communication network and a capacity parameter of the communication nodes connected to the synchronization sources;
selecting, by the network management system, a synchronization source to be used for synchronization of the communication network from among the at least two or more synchronization sources, according to a priority calculated based on the obtained quality parameter and capacity parameter; and
transmitting, by the network management system, a setting signal for setting the communication nodes in the communication network for synchronization of the communication network using a synchronization signal provided from the selected synchronization source.
