| 中文摘要: |
| 考虑现实大规模通信网络中负载流量的动态变化,以及局域拥塞状态对路由的影响,引入一个带有可调参数的级联故障模型.对比了同质的ER(Erds-Rényi)随机网络和异质的BA(Barabási-Albert)无标度网络由蓄意节点攻击引发的级联行为,探讨了不同拓扑网络的包产生速率、路由参数和规模对故障传播的影响.依据临界包产生速率这种新的度量网络鲁棒性指标,通过仿真发现,拓扑结构对网络最优路由参数值以及不同网络规模上的攻击效果都产生重要影响. |

| Considering dynamic change of load flow and the effect of local congestion status on routing in real large-scale communication networks,a cascading failure model with tunable parameters is introduced.Cascading behaviors in homogeneous ER(Erds-Rényi) random and heterogeneous BA(Barabási-Albert) scale-free networks subject to intentional attacks on node are compared,and the effect of packet generation rate,routing parameter and size of different topological networks on the failure propagation is investigated.According to the critical packet generation rate which is a new measure to the robustness of a network,it is found through simulation that topological structure can make important influence on the optimal value of the routing parameter and the effect of the attacks on different network sizes. |
