摘　　要：考虑军事通信网中节点的不同功能属性、节点之间的关联协作和信息流动的方向性,结合网络流理论,构建一种符合军事通信网特征的网络流路径模型。在此基础上定义基于时延的通信可靠性和通信节点重要度,用以表征网络实际运行的可靠性。分析军事通信网在一般情况和突发性情况下的通信可靠性,结果显示通信可靠性均存在峰值,反映出军事通信网的可靠通信能力,进而计算通信节点的重要度,找出网络的瓶颈节点。通过分析通信节点负载情况,验证了该模型的有效性。Considering the different functions of nodes, the collaboration of different nodes and the directionality of information flows,a network flow path model is established which matches the features of military network,according to the network flow theory. Then the communication reliability and the importance of communication nodes are defined based on the communicating delay based on this model,which can reflect the reliability of network in running. After that, the communication reliability of military communication network is analyzed in general case and emergency case. The result shows that it exists peak of communication reliability in two cases, which suggests the reliable communication capability of military communication network. And the importance of communication nodes is calculated, then the bottleneck nodes are found through that results. Finally the validity of this model is verified by analyzing the load of communication nodes.
