随着计算机网络的不断扩大，选择一种合适的路由技术尤为重要．本文从ＯＳＰＦ的链路状态数据库、最短路径优先算法和ＯＳＰＦ通信协议等几个方面分析了ＯＳＰＦ的路由技术，说明了采用此技术在网络扩展性、安全性和收敛性方面具有一定优势．同时阐述了在某重大ＩＰ宽带网中采用此技术所进行的路由规划和优化工作，它对于保证ＩＰ宽带网的扩展性和健壮性，优化网络性能具有重要的意义．
With the continuous expansion of computer networks, choosing a suitable routing technology is particularly important. This paper analyzes the OSPF routing technology from several aspects such as OSPF link state database, shortest path first algorithm and OSPF communication protocol. It shows that this technique has certain advantages in terms of network scalability, security and convergence. At the same time, it describes the routing planning and optimization of this technology in a major IP broadband network, which is of great significance to ensure the scalability and robustness of IP broadband network and optimize the network performance.
