基于CACTI的BGP多路径数据监测分析

CACTI Based Monitoring and Analysis of BGP Multipath Data

针对BGP缺乏有效的多路径实现的问题,设计并实现了一个基于CACTI的BGP多路径数据监测分析平台,通过给BGP协议配置多出口鉴别(MED)属性,利用BGP路由表及CACTI流量监测图,在实验平台上实现了对MED策略路由的验证.实验结果表明:监测分析平台不但有利于BGP故障的发现,而且也可以减小新策略的盲目部署对运行中的现网造成的不利影响,并为新策略在现网的部署提供了保证.

Given that BGP lacks effective multipath,a platform for BGP multipath data monitoring and analysis was designed and built.This BGP was equipped with multi-exist discriminator（MED） property and the experimental platform could demonstrate strategic routing of MED by using a BGP routing table and CACTI traffic monitoring charts.The monitoring and analysis platform was not only useful in determining BGP malfunction,but also could decrease the negative effects of blind deployment of new strategies on existing networks as well as ensure the deployment of new strategies on existing networks.
