MED路由策略研究

Study of MED Routing Policy

边界网关协议是目前用于广域网中最主要的域间分布式动态路由协议,具有丰富的路由控制机制。MED属性的使用不当通常会引起热土豆路由和MED振荡。介绍热土豆路由和MED振荡,总结分析了避免热土豆路由和MED振荡的方法,并针对广域网和专网分别提出了整体的MED路由策略,最后利用仿真软件加以验证。

At present,border gateway protocol is a mostly dynamic,distributed and inter-domain routing protocol used in WAN,it has plenty of routing control mechanisms.The inappropriate using of the MED attribute commonly induces to the hot potato routing and the persistent MED oscillation.In this paper,hot potato routing and the persistent MED oscillation are presented and the way of avoiding hot potato routing and the persistent MED oscillation are included and the routing algorithm with the med attribute is introdu...
