Method, apparatus and system for managing optical network unit DPU device

Abstract

The invention discloses a method, an apparatus and a system for managing an optical network unit DPU device. A specific business bearer channel is established between an optical line terminal OLT and an optical network unit DPU; a permanent management agent PMA of the OLT receives a NETCONF configuration message from a configuration server, and sends a management message of a management object to the DPU by the specific business bearer channel; the specific business bearer channel is terminated by the OLT and an optical network unit ONU of an adjacent device of the OLT, the OLT and the ONU separately extract the NET-CONF message to a device management CPU, and the OLT and the ONU establish a transparent channel for bearing a NET-CONF protocol. Therefore, the problems of high management complexity and poor extensibility of the optical network unit DPU device are solved, the management complexity is lowered, the extensibility is improved, and the maintenance cost is reduced.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a device management method, device and system for an optical network unit (DPU). Background technique [0002] A distribution processing unit (DistributionPointUnit, DPU for short) device only refers to a device placed on a branch point (DistributionPoint, DP for short) node. The network side is a passive optical network (Passive Optical Network, referred to as xPON) / Ethernet uplink port, and the user side is a VDSL2 / G.FAST digital subscriber line (Digital Subscriber Line, referred to as DSL) interface. In related technologies, the current DPU device management model The network configuration NETCONF protocol is adopted, which generally carries the IP protocol. If the uplink device is an optical line terminal (abbreviated as OLT), then the permanent manager agent (Permanent ManagementAgen, referred to as PMA) can be placed on the OLT device, even if the OLT and the Optical ...

AI Technical Summary

Problems solved by technology

If the uplink device is an optical line terminal (abbreviated as OLT), then the permanent manager agent (Permanent ManagementAgen, referred to as PMA) can be placed on the OLT device, even if the OLT and Optical Network Unit (referred to as ONU) are adjacent If the equipment still adopts the IP bearer mode, then it is necessary to configure IP addresses on both the OLT and the DPU, which involves issues such as IP address allocation and management, which brings complexity to network management and increases the complexity of the DPU equipment

[0003] The current conventional management method is to use the IP address management method. figure 1 It is a schematic diagram of the manner in which IP addresses are used to manage DPU devices in...
