Abstract: This paper puts forward a scalable design of OSPF topology monitoring system in resource, cost, configuration and application mode to aim at the existing problems in the management of OSPF network. Meanwhile, it gives the adjacency & passive design of Link State Advertisement(LSA) collector, topology discovery and link-break detection algorithm based on LSA. The experimental result and analysis show that the new system has the features of high scalability and correctness compared with the similar systems in the large-scale network environment.

Key words: Link State Advertisement(LSA), topology monitoring, centralized, distributed

摘要： 针对当前开放最短路径优先(OSPF)网络管理中存在的问题，提出一种OSPF网络拓扑监测系统在资源消耗、应用成本、配置项以及应用方式等方面的可扩展性设计。给出采集器的邻接被动式设计和基于链路状态信息的拓扑生成算法以及链路中断检测技术。试验及分析表明，该系统在大规模网络环境下与同类系统相比，具有可扩展性强、准确性高的特点。
