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.

摘要： A bandwidth scheduling method. The method includes a bandwidth allocation apparatus receives a bandwidth request message sent by a message conversion apparatus, where the bandwidth request message includes a bandwidth requirement, and the bandwidth requirement is a bandwidth required by a user-side apparatus for completing transmission of a service. The bandwidth allocation apparatus calculates first bandwidth grant information and second bandwidth grant information based on the bandwidth requirement, where the first bandwidth grant information is information about a bandwidth that is allocated to the user-side device, and the second bandwidth grant information is information about a bandwidth that is allocated to a second access device. The bandwidth allocation apparatus sends the first bandwidth grant information to the user-side device, and the bandwidth allocation apparatus sends the second bandwidth grant information to the second access device by using a first access device.
