Abstract: Currently most of the methods and tools of monitoring inter-domain routing stability available are from the macro point of view and the parameter is simple，some of the metrics only count the number of updates which can not offer particular information for eliminating routing faults.The paper designs and implements an effective monitoring tool for inter-domain routing stability，which analyzes the basic point based on binary group of（peer，prefix） or prefix according to routing updates and can reflect the status of inter-domain routing stability.The tool is good to meet requirements by applying the data collected from practice routing environment.

摘要： 目前域间路由稳定性监测分析方法和工具大多从宏观角度出发，反映路由稳定性状况的参数指标单一，有的甚至仅对路由更新信息进行了简单的分类统计，不能为故障排查提供更为详尽的依据。设计并实现了一种有效的域间路由稳定性监测工具，在更新消息层面上针对（对等体、前缀）二元组或前缀为基点展开分析，多方面反映了域间路由稳定状况。通过应用实际的相关路由信息进行分析，验证了工具的有效性。
