为了提升专用网在无线信道环境下的整体性能,该文对开放最短路径优先(open shortest path first,O SPF)协议进行了优化研究。研究主要包括单区域机制、相关数据包简化、状态机简化以及协议关键参数设置。仿真结果表明:在恶劣信道环境中,路由表平均计算次数可减少81%,协议带宽平均损耗可降低80%,而网络稳定工作时间可延长2倍。针对O SPF标准协议的优化设计简单可行,适应于专用网自身特点,可有效提高网络性能。 In order to improve the overall performance of private network in wireless channel environment, this paper optimizes the open shortest path first (O SPF) protocol. The research mainly includes single-area mechanism, simplification of related data packets, simplification of state machine and setting of protocol key parameters. The simulation results show that the average number of routing tables can be reduced by 81% and the average bandwidth of protocol can be reduced by 80% in harsh environment, while the network stability can be extended by 2 times. Optimized design for O SPF standard protocol is simple and feasible, adapted to the characteristics of private network, which can effectively improve network performance.
