通信网络抗毁性的评价方法

A Method of Evaluating the Invulnerability of Communication Networks Structure

基于多抗毁性度量值的评估技术,以作战运用的视角,对通信网络的抗毁性进行评价。首先,从通信网络抗毁性的定义出发,构建了通信网络拓扑结构的抗毁性评价模型。在所建模型中,选取了用户较为关心的网络抗毁性量度,方差的引入弥补了以往的量度不能体现个体差异的不足。其次,采取的点打击策略没有按度的大小进行打击,而是取路径中出现次数最多的点进行打击,这更符合实际情况。最后利用模型对实例进行了分析,结果表明模型不仅能够评价通信网络拓扑结构的抗毁性,而且还能指出网络结构需要优化的地方。

Based on the evaluation technology of multi - value about invulnerability, the invulnerability of the communication networks is evaluated in the view of battle. First, an evaluation model is built. In the model, some invulnerable indexes about which the clients are concerned are selected. The variation can incarnate the fluctuation of individuals. Second, the strategy of attacking vertexes, which has been used in many articles, is not adopted. But the more practical strategy is that the vertex which emerges most frequently in paths is searched and attacked. Finally an example of network is analyzed by using the model, the analysis result shows that the model can be used to evaluate the invulnerability of the communication networks and tell that which part of the network structure needs optimization.
