【摘要】：在域间路由中,BGP的最优路径转发规则使得节点无法控制自身能够收到哪些路径。针对该问题,提出了一种按需的域间路径构建方法,其主要特点为上游节点可以对其下游节点的选路过程施加影响,根据自身需求定制路径。首先对BGP进行扩展,提出了一种支持在路径通告中嵌入更多策略信息的域间路由协议P-BGP,嵌入在路径通告中的策略能够指导中间节点如何选路。在P-BGP的基础上,进一步提出了支持按需的域间路径构建方法OIPBM,OIPBM以BGP保证源端与目的端的可达性,需要构建特殊路径的源端将路径构建的需求信息发送至目的端,由目的端协助其发起一个带策略的P-BGP收敛过程获取满足需求的路径。在理论分析的基础上,通过实验验证了OIPBM具有较好的性能。
[Abstract]:In inter domain routing, the optimal path forwarding rules of BGP make nodes unable to control which paths they can receive. In view of the problem, an on-demand inter domain path construction method is proposed. The main feature is that the upstream node can influence the routing process of its downstream nodes and customize the path according to its own requirements. First, the BGP is entered into the path. An interdomain routing protocol (P-BGP), which supports more policy information embedded in path announcements, is proposed. The strategy embedded in the path notification can guide the routing of the intermediate nodes. On the basis of P-BGP, the method to support the on-demand inter domain path construction (OIPBM) is further proposed, and OIPBM guarantees the reachability of the source end and the destination with BGP. In nature, the source end of the special path is needed to send the requirement information of the path construction to the destination, and the destination is used to assist it to initiate a P-BGP convergence process with the strategy to obtain the requirements. On the basis of the theoretical analysis, it is proved that the OIPBM has good sexual energy through the experiment.
