| 摘 要： | 边界网关协议 (BGP-4 )支持的策略路由在互联网运行效率和安全方面发挥着重要作用 ,并直接涉及经济利益问题。为了对其进行测试 ,首先讨论了策略路由中所涉及的服务提供者与客户之间的基本关系 ;在分析路由属性与路由策略等概念的基础上 ,定义了路由行为与策略的一致性关系及两类违反一致性的情况。为了获得较好的测试效果 ,在测试手段上综合使用了主动的测试方法和被动的测试方法。这些技术和方法的正确性、有效性在实际测试活动中得以证实 ,并为网络的运行、管理提供了有益的指导

| Abstract: | Policy based routing affects the efficiency and security of the Internet transfer of sensitive financial information and is one of the most important features of Border Gateway Protocol Version 4 (BGP 4). Policy based routing was evaluated using the basic relations between autonomous systems (AS). Definitions were given to describe the attributes of the route, the policy, and the conformance relation between the behavior of the border gateway and the policies. The two main types of policy violations were classified as "leaking" and "penetration". The active testing and the passive testing were combined to achieve ideal coverage. Actual tests verified the validity of the analysis and provied guidance for network management. |
