Embodiment Construction

[0058] The method for managing optical network units or optical network terminals of the present invention is proposed on the basis of detailed analysis of the existing defects in the prior art. In the existing management methods, the ONT / ONU is regarded as an accessory device of the OLT , all management data is sent to ONT / ONU through OLT. In this way, for complex ONT / ONU (such as MDU), when managing ONT / ONU through OMCI protocol, OLT needs to send a lot of management data. As a result, the burden on the OLT is too large. Therefore, the present invention supports independent management protocol stack (such as SNMP protocol stack or other management protocol stack) on ONT / ONU, and configures the management IP address of ONT / ONU, realizes EMS and ONT / ONU on the management agreement Directly manage the connection of information, thereby reducing the burden on the OLT.

[0059] With reference to Fig. 4, the system structure of the present invention comprises: network element man...

Abstract

The invention provides a system and method of managing light network unit or light network terminal, it relates to fields of network communication and used to resolve problems that when multiple users are connected with ONT / ONU, the management mode of ONT / ONU is complex, the load of OLT is too big. The system includes EMS, OLT and ONT / ONU, said ONT / ONU is used to parse management data which is sent to ONT / ONU by EMS, package the management data of ONT / ONU then send to EMS. By said technique scheme provided in the invention, the invention supports management protocol at ONT / ONU, distributes the IP address of ONT / ONU, realizes the direct connection of EMS and ONT / ONU at management protocol, so the load of OLT is decreased, the problem that the ONT / ONU can not be a unattached net element to manage.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a system and method for managing optical network units or optical network terminals. Background technique [0002] Current broadband access technologies are mainly divided into copper wire access technologies (such as various DSL technologies) and optical access technologies, and users are connected to broadband networks through various access technologies. The central office equipment using optical access technology is called OLT, and the terminal setting is called ONT / ONU (optical network terminal / optical network unit). The reference configuration is shown in Figure 1: [0003] The application scenario of FTTH (Fiber to the Home) is that the OLT is connected to the ONT / ONU deployed in the home user through optical fiber, which is called fiber to the home. [0004] The application scenario of FTTB (Fiber to the Building) / FTTC (Fiber to the Curb) is that t...
