Abstract: In order to study the role of different types of nodes in the network during the failure propagation process and its impact on cascading failures, this paper uses the aggregation to investigate the load transfer efficiency of different network nodes. Firstly, the aggregation is used to describe the characteristics of network topology changes when a node fails. Through the aggregation, a network cascading failure model is established. Then the model determines the critical failure path of the network. Finally, through case analysis, it is found that the traffic network is more stable and has improved liquidity after aggregation changes.

Key words: reliability, cascading failure, network nodes, topology

摘要: 本文从可靠性角度定义了影响级联失效过程的关键指标,探讨网络不同类型节点在失效传播过程中的作用及其对可靠性的影响。通过节点聚合描述不同节点的失效传递,以及节点失效时的网络拓扑结构变化特征,从而构建网络级联失效模型,然后确定网络的关键失效路径。最后通过案例分析,发现交通网络在经过聚合变化后稳定性更强,流通性也有提高,验证了该模型的有效性。
