摘要
提出了一种BGP无效路由实时检测方法.该方法通过对路由的地址前缀进行所属关系鉴别来确定AS所声明前缀的有效性.对AS关系进行了推导,得到Internet的AS拓扑结构.依据自治系统间关系和路由通告原则,通过分析BGP路由的AS路径属性来发现违反AS关系的路径和伪造的AS路径.仿真实验结果表明,所给方法能够有效发现无效的BGP路由信息.
A method to detect BGP invalid routes is proposed. The method discovers invalid address prefix through checking the ownership of the prefix in a route. The Intemet topology based on ASes relationships inferred from routes information is constructed. According to the commercial relationships between ASes and routes export rules, the method detects AS path attribute to fred the invalid routes whose AS path attribute containing bogus AS number and AS path violating AS relationships. Simulation result shows that the method can efficiently fred BGP invalid routes.
