Design of Fast Discovery System of Network Topology Based on OSPF

针对当前网络拓扑发现中存在的问题,提出了一个基于OSPF的快速网络拓扑发现方法,讨论了拓扑信息添加、修改和拓扑图绘制的详细算法,并分析了拓扑信息转换算法的性能和特点。文章还就拓扑信息的快速图形化显示技术作了讨论并给出了实现的关键技术。实验表明,该系统在广域网环境下,与同类系统相比具有拓扑发现速度快、显示效果好等特点。

The article puts forward a lust discovery algorithm for network topology based on OSPF to aim at the existing problems in the network topology discovery system. Then it discusses the algorithm of adding, modifying topology information and drawing topology map, and analyses the performance and characteristic of this algorithm. It also discusses the technology of fast displaying topology information with graph and the key techniques to implement the display system. The experimental result shows that the new system has the features of fast discovering the topology and good displaying effects compared with the similar system in the WAN environment.
