Data synchronization method and system, and optical network unit

摘要

Embodiments of the present disclosure provide a data synchronization method and system, and an optical network unit. An ONU receives synchronization data that is transmitted by a first OLT through a GEM port corresponding to a predetermined GEM port ID or a logical link corresponding to a predetermined LLID, and stores the synchronization data. When a fault occurs on the first OLT or on a backbone optical fiber connected to the first OLT, the ONU transmits the synchronization data to a second OLT so that the second OLT recovers services according to the synchronization data.

1. A data synchronization method, comprising:
receiving, by an optical network unit (ONU), synchronization data that is transmitted by a first optical line terminal (OLT) through a gigabit passive optical network encapsulation method (GEM) port corresponding to a predetermined GEM port identification or a logical link corresponding to a predetermined logical link identification (LLID), and storing the synchronization data; wherein the predetermined GEM port identification, or the LLID, is dedicated for use for transmission of the synchronization data; and when a fault occurs on the first OLT or on a backbone optical fiber connected to the first OLT, transmitting, by the ONU, the synchronization data to a second OLT without parsing the synchronization data, so that the second OLT recovers services according to the synchronization data.
