EPON_EoC网络拓扑分层显示的设计与实现

Design and implementation of multi-layer display for EPON_EoC network topology

EPON+EcC作为三网融合中双向改造的主流方案,为其构建统一网管系统是必要的,而以图形方式显示网络拓扑结构是网管系统的基本要求之一。在已实现的EPON和EoC设备统一管理方案及拓扑发现的基础上,结合Twaver SVG进行了网络拓扑多层显示的设计与实现,并完善了拓扑编辑、拓扑导出等功能。同时,在此基础上也实现拓扑显示与告警管理模块的交互,在拓扑上实现设备端口告警和告警传播。

EPON_EOC has become the mainstream proposal in bidirectional transformation for Triple-play,it＇s necessary to equip it with a unified network management system（NMS）.And one of the basic requirements of NMS is that displays the network topology by graphical.Based on the realized unified management scheme and topology discovery of EPON_EoC,the design and implementation of multi-layer display for EPON_EoC are achieved by Twaver SVG,as soon as topological editing,topological deriving and so on.By the interaction with alarm management,the alarms on device port and alarm transmission are implemented in topology,too.
