摘要
电力骨干通信网抗毁性分析对于评价电力通信网络的生存性能,制定网络的保护策略具有重要的意义。结合复杂网络异构性,基于电力骨干通信网拓扑结构,构建了网络节点差异性矩阵。依据电力通信的业务特点,将链路传输流量作为链路的权重,构建了网络链路差异性矩阵。融合节点及链路差异性定义了节点重要度及电力骨干通信网的结构熵。以一个实例网络对网络的节点重要度及蓄意攻击下以结构熵为指标的网络抗毁性进行了仿真分析,结果表明了所提方法的合理性和有效性。
It is of great significance to analyze the invulnerability of electric power backbone communication network for evaluating the survivability of electric power communication network and formulating network protection strategies.Based on the heterogeneity of complex networks and the topological structure of electric power backbone communication network,the network node difference matrix is constructed.According to the characteristics of power communication services,the network link difference matrix is constructed with regarding the link traffic as the link weight.Combining the differences of nodes and links,the importance of nodes and the structural entropy of electric power backbone communication network are defined.For a practical network,the simulation analysis of node importance and network invulnerability under intentional attack based on structural entropy is carried out,and the results show that the method proposed in this paper is more accurate and effective for electric power backbone communication network than other comparative methods.
