摘要： 为提高域间选路协议的扩展性能、收敛性能和路由质量，设计了一种基于链路状态机制的域间选路协议。首先对自治系统级网络的状态进行建模，结合域间连接的链路状态信息，利用最短路算法进行域间路由计算。讨论了路由模型及选路策略的实施机制，分析了协议的性能并和BGP进行了对比。分析和仿真表明，基于链路状态机制的域间选路协议能够减小域间路由表的大小，加快收敛速度并提高路由质量。

Abstract: To improve scalability, convergence and route quality of inter-domain routing, a link-state based inter-domain routing protocol is designed. The status of autonomous system level network is first modeled. Combined with the status information of inter-domain connections, the shortest path algorithm is implemented to calculate the inter-domain route. The routing model and the mechanism of inter-domain routing policy are discussed.The protocol performance is analyzed and compared with BGP. The analysis and simulation results show that the link-state based inter-domain routing protocol can reduce routing table size,and improve convergence and route quality.

Key words: inter-domain routing protocol, link-state, border gateway protocl
