该文提出了OSPF(openshortestpathfirst)链路摆动抑制算法以克服由于无线信道误码率较高而引起的专用网链路摆动问题。该算法核心思想是在保证网络连通性的基础上,评估所有链路性能并对不稳定链路进行动态抑制。链路在被抑制的状态下不参加路由计算。仿真结果表明:在算法参数设置合理的情况下,链路状态广播更新数量和网络同步运行时间等指标可分别改善约35%和10%。OSPF链路摆动抑制算法简单可行,适应于专用网自身特点,可有效提高网络整体性能。
This paper proposes OSPF (openshortestpathfirst) link swing suppression algorithm to overcome the problem of the private network link swing caused by the high bit error rate of the wireless channel. The core idea of this algorithm is to evaluate the performance of all links and dynamically suppress the unstable links based on network connectivity. The link is not involved in route calculation while being suppressed. Simulation results show that when the parameters of the algorithm are set reasonable, the number of link state broadcast updates and network synchronization running time can be improved by about 35% and 10% respectively. OSPF link swing suppression algorithm is simple and feasible, to adapt to the characteristics of the private network, which can effectively improve the overall network performance.
