摘　　要：介绍了采用ns-3仿真分析“IP骨干网络中链路故障对全网负荷影响”的方法。通过在ns-3中建立的网络仿真系统(NSS,Network Simulation System),构建了高承载的支持动态路由的骨干网络,并发送仿真网络流量,计算了网络故障带宽,分析单链路故障对全网负荷的影响。为骨干网带宽扩容中的故障带宽分析、网络安全分析提供建议。This paper introduces a method of using ns-3 to simulate and analyze the load change in the IP network backbone.By constructing the high-loading backbone network with dynamic routing protocols supported using ns-3 called Network Simulation System(NSS),and sending simulated network flows,we analysis the network fault bandwidth of the backbone,and its reflection to the whole network load.We offer some suggestion in the fault bandwidth analysis and network security analysis for the backbone bandwidth expansion.

关 键 词：故障带宽 ns-3 网络扩容
