Abstract
Description
technical field
[0001] The present invention relates to the technical field of gigabit passive optical network (Gigabit Passive Optical Network, GPON), in particular to a remote configuration optical network unit (Optical Network Unit, ONU) precision time synchronization protocol (Precision Time Protocol, referred to as PTP or 1588) Methods, apparatus and systems for business. Background technique
[0002] IEEE 1588v2 is a precision time synchronization protocol for network measurement and control systems, that is, PTP or 1588, which can achieve frequency and phase synchronization. PTP adopts the master / slave synchronization method, that is, the master and slave devices complete the synchronization function based on the sending and receiving time stamps of network data packets. GPON can complete the clock and time synchronization in the following way. The optical line terminal (Optical Line Terminal, OLT) connects to the time source to obtain time information, and then tran...
