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.To improve scalability, convergence and route quality of inter-domain routing, a link-state based interdomain 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 interdomain 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 the routing table size, and improve convergence and route quality.
