【摘要】：随着社会与科技发展,基础设施网络之间的相互关联日趋复杂。为研究它们之间的关联关系对网络带来的影响,在对基础设施网络进行物理结构特性分析的基础上,提出一种基于网络图和泰森多边形的基础设施网络建模方法,在模型构建的基础上,研究对比网络独立运行和关联运行时效能的变化以及网络中不同节点故障对网络效能的影响。实验结果表明:故障在关联基础设施网络之间的传播比在独立网络中更为迅速,受故障影响,网络效能下降速度更快;网络中不同节点失效对网络效能影响程度不同,基础设施网络间的关联关系会使节点的重要性发生改变。这一结论为发现和识别网络中基础设施网络重要节点,加强重要节点的预防保护和故障发现后的应急策略提供了理论依据与决策支持。
[Abstract]:With the development of society and science and technology, the interrelation between infrastructure network is becoming more and more complex. In order to study the influence of the relationship between them on the network, an infrastructure network modeling method based on network diagram and Tyson polygon is proposed based on the analysis of physical structure characteristics of infrastructure network. Based on the model construction, the effects of different node faults on the network performance are studied and compared between the independent network and the associated network. The experimental results show that the fault propagates more rapidly in the associated infrastructure network than in the independent network, and the network efficiency decreases more quickly due to the fault, and the different node failure in the network has different influence on the network performance. The relationship between infrastructure networks can change the importance of nodes. This conclusion provides a theoretical basis and decision support for the detection and identification of the important nodes in the infrastructure network and for strengthening the preventive protection of the important nodes and the emergency strategy after the fault detection.
