摘　　要：BGP和OSPF是目前网络中普遍使用的域间和域内路由协议,路由协议的运行状态直接影响网络性能。本文设计和实现了一个通用的路由监控分析系统,能实时收集路由信息,自动生成域间域内拓扑,提供历史拓扑信息的浏览和重放、拓扑图的比较、路由信息的解析和统计等功能,并能够分析路由收敛和稳定性,从而辅助网管人员掌握网络路由系统实时运行状况,做出相应的管理决策。BGP and OSPF are two protocols widely used for inter-and intra-domain routing. Their working states have deep influence on network performance. This paper designs and implements a general route monitoring and analysis system. The system collects routing information in real-time, and parses the information to automatically generate inter- and intra-domain topology. The system generates history topology graphs so that users can easily browse and compare them. It also analyzes the muting convergence and stability based on the statistics of the collected routing information. With the help of these convenient functions, network administrators can manage the real-time state of a routing system and take the corresponding operation.
