Title:
SELF-ADAPTIVE METHOD FOR REALIZING 1588 TIME SYNCHRONIZATION IN UNICAST MODE
Document Type and Number:
WIPO Patent Application WO/2018/041044
Kind Code:
A1
Abstract:
Disclosed is a self-adaptive method for realizing 1588 time synchronization in a unicast mode. The method comprises: during the stage of establishing a master-slave relationship, in an event processing method of each clock network element, increasing an actively sent notification message based on the established master-slave relationship in a negotiated unicast mode; during the stage of calculating a deviation and performing adjustment, in an event processing method of a master clock network element, increasing an actively sent synchronous message and an actively sent delay request response message based on a master clock event processing method in the negotiated unicast mode; and in an event processing method of a slave clock network element, increasing an actively sent delay request message based on a slave clock event processing method in the negotiated unicast mode. According to the present invention, the negotiated unicast mode is improved; therefore, when performing 1588 time synchronization in the unicast mode, the network elements in the present invention do not need to appoint a unicast intercommunication mode with opposite sides in advance, thereby ensuring intercommunication in any unicast mode.
