Method of accessing optical network unit management and control interface (OMCI) entity from application layer

Abstract

The invention relates to the field of optical communication techniques, in particular to a method of accessing optical network unit management and control interface (OMCI) entity from an application layer. With presetting an operation-interface, independent progresses of optical network units (ONU) can achieve the operations of establishing, setting, reading or deleting, and the like to OMCI entity data through transferring the operation-interface and independent from the management of an optical line terminal (OLT). Meanwhile, conflicts can be avoided and the operability and flexibility to the ONU configuration and operation can be increased so as to be favorable to the ONU customization of manufacturers.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a method for accessing OMCI entities from an application layer. Background technique [0002] GPON (Gigabit-Capable PON) technology is the latest generation broadband passive optical integrated access standard based on the ITU-TG.984.x standard. It has many advantages such as high bandwidth, high efficiency, large coverage, and rich user interfaces. Most operators regard it as an ideal technology to achieve broadband and comprehensive transformation of access network services. [0003] figure 1 It is a schematic structural diagram of a GPON application mode in the prior art; as figure 1 As shown, the GPON system includes optical nodes (Optical Network Unit, referred to as ONU), optical network equipment (Optical Network Terminal, referred to as ONT) and passive optical distribution network; among them, OLT provides network side and core network (such as Video ser...

Problems solved by technology

[0007] However, when other processes in the ONU system need to access the OMCI entity data to configure the OMCI entity, because the ONU applications in the prior art all implement OMCI in a traditional way, and the OMCI process is the manager of the OMCI entity , so it can only rely on the active configuration of the OLT to realize the access to the OMCI entity, and does not develop an independent set of interfaces for the application layer to realize the configuration function of the OMCI entity, only the access to the entity data information saved by OMCI, That is, the operation of creating, setting, reading and / or deleting OMCI entity data from the application layer cannot be realized, which makes the configuration operation of the ONU relatively simple, which is not conducive to the customization of the ONU manufacturer
