EPON网络拓扑管理系统

针对大规模异构EPON（EPON：Ethernet Passive Optical Network）网络，为了提高EPON网络的管理水平和维护效率，并且能够更直观地显示EPON网络内部设备拓扑关系、网络工作实时状态和告警等重要信息，需要设计一个EPON网络拓扑管理系统对EPON网络进行有效管理.本文首先介绍了拓扑管理系统设计与实现方案，将整个系统其划分为采集、处理、显示三大模块.数据采集层采用基于TL1通信协议获取网络信息，处理层基于MVC（Model View Controller）的模式设计和开发B/S（Browser/Server）架构的集中处理系统，拓扑显示层的GUI应用HTML5 Canvas标签实现.最后通过搭建测试环境，证明了设计方案是可行和高效的.

Topology Management System for EPON

Because the scale of EPON network increases rapidly, it is required to design an EPON network topology management system in order to improve the management and maintenance of EPON network, which can intuitively display the EPON network topology structure, the network working status and alarm in real time. Firstly, the design and implementation of topology management system is introduced. The designed system is divided into structure of three levels including acquisition, processing and view. The acquisition layer employs the TL1 communication protocol mode to get network information. The processing layer uses B/S structure and processing system is based on MVC model. The GUI of display layer employs HTML 5 Canvas tag to display the topology relationship. And finally, through constructing the test environment, it proves the design is feasible and effective.
