Embodiment Construction

[0053] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0054] The invention applies the management object instance index in the OAM protocol data unit, realizes fine remote management of each management object and its instance of the ONU, and is also convenient for intercommunication between different manufacturers' equipment. First of all, let me introduce the so-called management object instance index. This management object instance index mechanism can adopt the "type-length-value (TLV)" structure, using a management object instance index TLV introduced in the OAMPDU stipulated in IEEE802.3-2005 to identify the specific instance of the management object targeted by one or more variable descriptions / containers (Variable Descriptor / Container) for its attributes immediately following the TLV.

[0055] As shown in Figure 2, it is a schematic diagram of the basic format of t...

Abstract

The present invention relates to the remote management method of a optical network unit; the method comprises that an optical circuit end receives the order issued by a network management device for the implementation of the remote management of relevant property / operation of the optical network unit, and judges whether the relevant property / operation needs the collocation and management object example index; if the index is needed, the optical circuit end forms the requirement information for remote management which comprises the management object example index and emits the information to the optical network unit; the end also receives the response information of remote management returned by the optical network unit and reports the information to the network management device. The present invention also relates to the remote management system of the optical network unit comprising an optical circuit end and an optical network unit; the optical circuit end comprises an order receiving module, an index judging module, a first requirement information-forming module, a requirement information-emitting module and a response information reporting module. The present invention realizes the expanded frame of the remote management through the management object example index and can realize the remote management of various management objects and examples of ONU.

Description

technical field [0001] The invention relates to the field of broadband optical fiber access, in particular to a method and a system for remotely managing management objects of an Optical Network Unit (ONU for short). Background technique [0002] With the rapid development of the Internet and new services and applications such as IPTV that put forward higher requirements for access bandwidth, optical fiber access has become an inevitable direction for the development of broadband access networks. Considering the maturity of technology and operating cost, Ethernet Passive Optical Network (EPON for short) is the most important means of realizing optical fiber access, and it is also the access technology with the most development potential. [0003] Since the EPON system adopts a bandwidth-sharing point-to-multipoint topology, as shown in Figure 1, each Optical Line Terminal 1 (Optical Line Terminal, OLT for short) is connected to multiple For each ONU3, downlink services are ...
