Embodiment Construction

[0024] Below according to accompanying drawing and embodiment the present invention will be described in further detail:

[0025] Since EPON adopts OAM channel to manage terminals, the OAM channel of EPON can be used for content expansion and perfection. The present invention aims at the problem that the current terminal management content is not perfect, and combines the internationally general XDSL terminal management technology (TR062 management standard) to manage the EPON terminal, so that the EPON terminal can be operated and managed, and the terminal interface is included. Complete management of terminals including management, service configuration management, performance data, and status management.

[0026] The present invention is established under a tree network, including EMS (Equipment management system, that is, equipment management system), optical line terminal (OLT), a plurality of optical network units (ONU1, ONU2...ONUn, here take ONU as an example to illust...

Abstract

A method for carrying out terminal management based on EPON includes connecting unit management system on optical line terminal based on EPON and setting up network management channel between them and between optical line terminal and each network terminal, carrying out analysis on message by optical line terminal when network management protocol message is sent to optical line terminal by unit management system, retransmitting message to network terminal by set up operation-maintenance channel when network protocol message is aimed at network terminal and retransmitting message reported from network terminal to unit management system by optical line terminal.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a terminal management method for an Ethernet-based passive optical network (EPON). Background technique [0002] In the increasingly large-scale broadband access network, most of the existing local area networks (LAN) run on the 100Mbit / s network, and many large-scale commercial companies are transitioning to Gigabit Ethernet (GE). On the metropolitan core network and metropolitan edge network, the bandwidth capacity of Synchronous Optical Network (SONET) / Synchronous Digital Hierarchy (SDH) / Gigabit Ethernet (GE) is very abundant, which creates a serious bandwidth bottleneck in the access network. . Compared with cable transmission, optical fiber transmission has the advantages of large capacity, low loss, and strong anti-electromagnetic interference ability. Therefore, as the cost of optical fiber transmission gradually decreases, the fiber opticization of the access netwo...
