摘　　要：结合某专用业务网网络拓扑结构、信息传输特点和业务传输需求,分析当前骨干网络路由设置存在的不足,通过分析路由信息协议(Routing Information Protocol,RIP)、开放最短路径优先(Open Shortest Path First,OSPF)、中间系统到中间系统(Intermediate System-to-Intermediate System,IS-IS)路由协议、边界网关协议(Border Gateway Protocol,BGP)等几种常用动态路由协议的特点和应用场景,结合网络模拟仿真结论,认为OSPF和IS-IS协议具有收敛速度快、层次化多区域结构设计、占用带宽少以及路由控制策略丰富等特点。通过合理的参数设置,可以满足某专用业务网“网络传输万无一失,链路故障代通时间不超过50 ms”的使用需求。This paper analyzes the shortcoming of the current backbone network routing by combining the topology,information transmission characteristics and service transmission requirements of a dedicated service network.By analyzing the characteristic and application scenarios of several commonly used dynamic routing protocols,such as RIP,OSPF,IS-IS,BGP,and combining with the network simulation conclusion,it is concluded that the OSPF and IS-IS protocols have the characteristics of fast convergence,hierarchical multi-area structure design,less occupied bandwidth,and rich routing control strategies.They can meet the demand of a special service network that“network transmission is safe and link failure time is less than 50ms”.
