摘要
为了解决实时域间路由动态监测的问题,提出了一种基于路由协议交互的域间路由监测方法。该方法通过一个具有部分路由引擎功能的监测代理连接网络,获取网络中的路由交互信息,通过对路由交互信息的分析,监测网络拓扑的变化情况以及其他网络动态行为。在实际工作中,实现了一个基于该方法的域间路由动态监测系统,并部署于第二代中国教育和科研计算机网CERNET 2中。该方法能够实时地分析域间路由的动态性,并且几乎不会对网络和路由器造成额外的负担。
A real-time, dynamic inter-domain routing monitoring system was developed with a inonitor agent partially implementing the border gateway protocol (BGP) engine. The agent can listen and receive BC-P routing update messages by peering with any BGP speaker in the managed BC-P network. The agent uses the collected routing information to re-construct the BC-P topology and analyze the BC-P dynamics. The system is implemented in the dynamic inter-domain routing monitor system deployed in CERNET2 (the second generation of China Education and Research Network). The system analyzes the inter-domain routing dynamics in real-time with less extra load for both the network and the touters.
