摘　　要：对AS间BGP路由策略进行了深入研究,给出了一种推断导出策略的方法。在此基础上,提出了一种基于AS关系的AS间BGP路由策略验证方法,通过该方法可以发现AS间异常的prefix宣告,从而可以实现对路由策略的验证。然后用该方法对AT&T的两个AS间的BGP路由策略进行了验证,取得了较好的效果。The paper investigates the route policy between ASs, then presents a method that can conduct new policies. On the basis of that, it also presents a method of between AS polices verification based on AS relationships. Through this method it can find out the abnormal prefix advertise to verify the route policies. It takes an experiment for the method between two ASs in AT＆T, and the results are good.
