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
The present invention relates to the communications field, in particular to a kind of optical network unit DPU device management method, Apparatus and system.
Background technology
Allocation process unit (DistributionPointUnit, referred to as DPU) equipment only refers to be placed on the equipment of branch point (DistributionPoint, referred to as DP) node.Network side is EPON (PassiveOpticalNetwork, referred to as xPON)/Ethernet upper united mouth, user side is VDSL2/G.FAST Digital Subscriber Line (DigitalSubscriberLine, referred to as DSL) interface, in the related, current DPU equipment control model adopts network configuration NETCONF agreement, and this agreement is generally by carrying IP agreement.If first line of a couplet equipment is optical line terminal (ticallineterminal, referred to as OLT), so persistence manager agency (PermanentManagementAgen, referred to as PMA) can be placed in OLT device, even OLT and optical network unit (OpticalNetworkUnit, referred to as ONU) it is adjacent device, if or adopt IP bearing mode, so it is accomplished by OLT and DPU all configuration of IP addresses, this relates to the distribution of IP address, the problems such as management, bring the complexity of network management, too increase the complexity of DPU equipment.
Way to manage conventional at present is the way to manage adopting IP address, Fig. 1 adopts the IP address schematic diagram to the mode that DPU equipment is managed in correlation technique, as shown in Figure 1, including subscriber terminal equipment (CustomerPremiseEquipment, referred to as CPE), the shortcoming of this mode is: each DPU is required for distribution IP address, and IP address is distributed, mark and management are extremely complex, open huge with maintenance workload.
nullAnother mode be between OLT and DPU use GPON (gigabit compares EPON，During the technology such as GPONGigabit-CapablePON)/XG-PON1 (ten thousand Gigabit-capable Passive Optical Network)，Special optical network unit management is used to control interface (ManagementandControlInterface，Referred to as OMCI) be the agreement of information interaction of a kind of OLT and ONT of definition in GPON standard) passage to be to carry NETCONF message，This passage is for the configuration between OLT and ONU and notice,Fig. 2 is the schematic diagram of the OMCI management passage in correlation technique between OLT and ONU，Fig. 3 is the schematic diagram adopting NETCONFoverOMCI way to manage in correlation technique，As shown in Figures 2 and 3.Based on the mode that the implementation of this passage is NETCONFoverOMCI, this function adopts PON underlying mechanisms, it is not necessary to configuration of IP address etc. just can realize OLT and ONU configuration management and ONU alarm notification.But in this OMCI passage, each OMCI message maximum byte is less than 53 bytes, if carrying NETCONF message with OMCI, then relating to NETCONF message fragment and restructuring, extensibility is very poor.
