为更加准确地评估军事通信网络(military communication network,MCN)拓扑抗毁性(topology survivability,TS),建立了基于节点功能类型的MCN拓扑模型;给出了T-CPUE(transport-collect,process,use,effect)信息功能链的概念,定义MCN拓扑抗毁性为使T-CPUE信息功能链保持连通的能力;分别基于节点连通度、链路结合度、节点重要度、链路重要度和T-CPUE信息功能链的连通度,提出了的5种MCN拓扑抗毁性指标。以某体系作战通信网络为例,分析了在逐渐移除最大度节点和最重要节点的策略下,网络的各种拓扑抗毁性随移除节点数的变化情况,验证了所提方法的合理性和有效性。
In order to evaluate the topology survivability of military communication network (MCN), a topology model of MCN considering nodes functions is built~ the concept of T-CPUE infor mation functional chain is given. Based on the definition of MCN topology survivability as connectivity degree among four types of terminal user of T-CPUE, five MCN topology survivability measures, including node connectivity, link connectivity, node significance, link significance and T-CPUE chain connectivity, is defined. With an example communication network in SoS operations, the rationality and validity of the proposed method is demonstrated by comparing variability of five topology survivability measures along with increasing of the deleted nodes number in accordance to two different node deleting strategies, i. e. deleting maximum degree node gradually and deleting the most vital node gradually.
