摘　　要：BGP是一个基于策略的路由协议,目前,由于BGP策略所引发的路由振荡在Internet中非常普遍,给网络稳定性健壮性都带来了很多负面的影响。网络仿真在路由稳定性研究中充当着相当重要的角色。用网络仿真的方法来研究和分析影响BGP路由稳定性的因素,是一个非常科学实用的研究方法和途径。The border gateway protocol (BGP) is the inter-domain dynamic routing protocol used to exchange reach ability information between autonomous system in the Internet. The policy-based configuration of the BGP will cause route oscillations, which can give rise to global routing anomalies.This paper presents a one-year study of the effect that BGP policies have on the route stability and the BGP convergence properties and analyses the simulated data of a classical model of three nodcs.Our analysis shows that the convergence time or/and the number of routing update packets is interrelated with a proper miniannounce-time in the BGP policies and a large delay-time in the link.
