Routing policy management method for multi-ISP collaboration
面向多ISP协同的域间路由策略管理方法

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.
