摘　　要：首先概述了在网络管理系统中探测网络拓扑的一般方法,然后根据GPON系统的结构特点,设计了基于SNMP协议的无源光网络中显示OLT和ONU拓扑结构的方案,并采用C++编写了网络管理端的探测显示模块,最后通过代理端的模拟收发系统,实现了网络管理站通过OLT代理实时发现ONU拓扑以及状态的功能。Firstly this paper gives a brief overview about the general network topology discovery method in network management system, then on base of the character of GPON structure and the reference of SNMP protocol, it designs a project which can discover and display the topology of OLT（Optical Line Terminal） and ONU（Optical Network Unit）in passive optical networks, and using C＋＋ language, we write a detection and display module at the network management station. Finally, by use of the simulative receive and send system at the agent side ,it achieves the function which can discover the topology as well as the status of ONU through OLT agent at the network management side.
