Management method of FTTH (fiber to the home)-type ONU (optical network unit) between EML (element management level) and NML (network management level)

Abstract

The invention discloses a management method of an FTTH (fiber to the home)-type ONU (optical network unit) between an EML (element management level) and an NML (network management level). The management method comprises the following steps: concealing application of a remote unit object, adopting locating information of a virtual frame, a frame, a slot or a disk, and modeling a single disk from each FTTH-type ONU; modeling a network element from each OLT (optical line terminal) and suspended ONU thereof, building the virtual frame for each network element, building a virtual machine frame for all ONUs suspended on the PON (passive optical network) port of each OLT side, building a virtual slot for each ONU, and carrying out synchronous configuration; automatically adding the virtual slot and the single disk when adding new ONU, deleting the ONU single disk and the virtual slot when deleting the ONU, expressing the relation of the ONU and the OLT side by building a remote connection point on the PON port of the ONU, and describing this layer information of the PON port by LR-PON. According to the invention, the locating information expression of the ONU between the EML and the NML can be simplified, and the managed virtual management object is reduced.

Description

technical field [0001] The present invention relates to the field of optical communication, in particular to an FTTH (Fiber To The Home, fiber to the home) type ONU (Optical Network Unit, optical network unit) management method. Background technique [0002] As the scale of FTTH application becomes larger and larger, operators propose to incorporate FTTH into an OSS (Operations support System, operation support system) management system, so as to adapt to their increasing OSS application requirements. [0003] At present, the international organization TMF (Tele Management Forum, Telecommunications Management Forum) is also developing the ONU management model. In the latest draft TMF (Tele Management Forum, Telecommunications Management Forum) draft 529 that is being discussed, it is clearly defined: the ONU is established as a network element The equipment container (Equipment Holder) of the remote unit (Remote Unit) below, when describing the equipment container, the posi...

AI Technical Summary

Problems solved by technology

The disadvantages are: (1) ONU is similar to ordinary single disk in type, but introduces two different positioning methods shown in Table 1

[0006] Domestic OSS manufacturers tend to manage a single FTTH-type ONU as an independent network element, and virtualize a network element, rack, frame, slot, and disk for each ONU, which will lead to a large increase in the number of objects in the memory. The advantage is that it can realize ONU and Ordinary single disks have the same positioning method to simplify the design of the management system; the disadvantages are: (1) FTTH will manage the OLT and the ONU attached to it as a unified logical function system, that is, network element management, and the ONU It is managed as the same network element object as the OLT, and its association relationship cannot be clearly expressed, so it is inconvenient to perform operations on various network elements

For example, the management relationship between OLT and ONU is not easy to express, and the difficulty of fault analysis increases

(2) Too many virtual management objects

[0008] (1) In the TMF draft, there are different positioning methods for single-disk objects, and the meaning of using remote units here is not clear

[0009] (2) In the existing schemes in China, a large number of objects will be generated, which will consume memory, and at the same time, the ONU and OLT will be managed equally, which cannot meet the requirements of managing the OLT and its attached ONUs as network elements.
