| 摘 要： | 针对网络系统中节点存在正常、亚健康、故障三种状态的情形,研究了网络系统亚健康状态下的性能退化评估方法。依据网络系统亚健康状态的特征及网络系统中节点之间的相互关系,深入探讨了影响网络系统效能退化的因素,提出了一种基于微分方程的网络系统亚健康状态的性能退化评估模型,进而预测亚健康网络系统未来可能发生的转化规律。理论分析及试验论证表明,所构建的模型具有一定的合理性,并具有良好的应用前景。

| Abstract: | The nodes in network systems have three statuses: normal,subhealth and fault.To better analyze the behavior of the network system,a performance degradation evaluation method is presented based on the subhealth network system.Firstly,the influencing factors of performance degradation in network systems are discussed.Then,the performance degradation evaluation model of subhealth network systems is presented based on differential equations according to the relationship between the subhealth state features and ... |
