Internet域间路由振荡问题分析与研究

Analysis and Research on Route Oscillations of Internet Inter-domain Routing Policy

边界网关协议(BGP)是Internet域间路由的事实标准,它允许各自治系统独立配置路由选择和播发策略,但这种局部配置可能导致全局策略配置冲突和低效,从而引起路由振荡的问题。文章分析了域间路由振荡问题,并综述了其相应的各种解决方案。

The Border Gateway Protocol(BGP)is the de facto inter-domain routing protocol and allows an Autonomous System(AS)to apply diverse local policies for selecting routes and propagating reachability information to other domains.However,BGP permits ASes to have conflicting and inefficient policies that can lead to route oscillations.In this paper,the analyse on route oscillations and a survey of all these algorithms and schemes are presented.
