摘　　要：针对高可靠等级网络规划中网络抗毁性评估及拓扑结构优化的问题,根据网络可靠性要求,综合考虑网络传输线路资源情况及建设成本等因素,对网络拓扑结构开展初步设计,通过仿真对网络节点或链路在不同概率随机故障或损毁情况下的网络连通度进行抗毁性测度。依据仿真结果,评估网络抗毁性是否满足网络可靠性要求,按需优化网络拓扑设计,进一步提升网络可靠性。实践表明,该方法是一种有效的网络拓扑结构优化方法。In order to solve the problem of network survivability evaluation and topology optimization in high reliability level network planning,the network topology is designed preliminarily,considering the network reliability requirements,the network transmission line resources and construction costs,and the network connectivity of network nodes or links under random failures or damages with different probabilities is measured by OMNeT++.According to the simulation results,the network survivability is evaluated to determine whether it meets the requirements of network reliability,and then the network topology design is optimized on demand for further improving the network reliability.The practice shows that it is an effective network topology optimization method.
