面向多ISP协同的域间路由策略管理方法

域间路由系统由多个自治系统互连而成，各自治系统根据自身的商业目标独立配置路由策略。由于各网络服务提供商（ISP）的策略隐私性以及边界网关协议（BGP）设计和实现上的缺陷，目前的域间路由系统在协同配置和协同安全方面存在明显的不足，对路由策略冲突，路由信息欺骗等问题缺乏有效的解决手段。域间路由协同策略管理方法采用分布式协同结构，利用隐私隐藏信息共享的方法，能够在实现自治系统隐私保护的前提下发现自治系统之间可能存在的路由策略冲突，解决各ISP在独立情况下无法进行的策略优化。

Routing policy management method for multi-ISP collaboration

Inter-domain routing system consists of several Autonomous Systems (AS), and they are connected to each other and configure their own routing policy. Currently, due to the privacy of policy of Internet Service Providers (ISP) and flaws of design and realization of Boarder Gateway Protocol (BGP), there are a lot of flaws in collaborative configuration and security, along with apparent deficiency to deal with the problems just like conflict in routing policy and routing cheating. To handle the problems mentioned above, a distributed system for collaborative configuration and policy check between multi ISPs was put forward, in which privacy protection technology was applied in the information sharing process, so that multi ISPs could work collaboratively to check policy consistence violation faults that could not be found out by themselves alone.
