Configuration method for optical network unit, optical network unit and optical line terminal

Abstract

The invention provides a configuration method for an optical network unit, the optical network unit and an optical line terminal. The configuration method for the optical network unit comprises steps as follows: the optical line terminal inquires operation administration and maintenance (OAM) attribute information of the optical network unit; the optical line terminal reads a value of a configuration counter in the OAM attribute information; and after determining that the value of the configuration counter in the OAM attribute information is different from the value of a locally stored configuration counter, the optical line terminal reconfigures the optical network unit by adopting configuration data corresponding to the value of the locally stored configuration counter. By using the configuration method, the optical line terminal transmits the configuration data to the optical network unit after the optical network unit is on line and the configuration data of the optical network unit is changed; and furthermore, the recovery time of the service of the optical network unit can be shortened, the user experience is enhanced, and the central processing unit (CPU) utilization due to the fact that the optical line terminal frequently transmits the configuration data can be reduced.

Description

technical field [0001] The invention relates to optical network communication technology, in particular to a configuration method of an optical network unit, an optical network unit and an optical line terminal, and belongs to the technical field of communication. Background technique [0002] Ethernet Passive Optical Network (Ethernet Passive Optical Network; hereinafter referred to as: EPON) technology adopts point-to-multipoint structure and passive optical fiber transmission, and provides access to various services based on Ethernet technology. It is currently the mainstream integrated broadband access method. [0003] In the existing EPON equipment, its processing flow is as follows: After the optical network unit (Optical Network Unit; hereinafter referred to as: ONU) device is successfully registered, the optical line terminal (Optical Line Terminal; hereinafter referred to as: OLT) device will send the ONU device After the ONU configuration data saved on the OLT dev...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, if the OLT device does not actively query the configuration data of the ONU device, it cannot perceive the change of the ONU device configuration caused by the local modification of the ONU device. After the ONU device goes online, the OLT device needs to download the online ONU device. send configuration data

If the user does not apply for a service change, the configuration data delivered by the OLT device is the same every time the ONU device goes online, and because the configuration data of most Fiber To The Home (FTTH) users are in the same It is the same in the network environment, and sending the same configuration data each time is a waste of bandwidth and increases the time for business recovery.
