Abstract:

The Software Defined Network(SDN) provides dynamic control of the network,but the security is poor.Therefore,a dynamic random network model of SDN is proposed to study the process of network virus spreading.Through theoretical analysis and numerical simulation,it is found that the propagation of network viruses from the source subnet to the target subnet is related to the mobility of the nodes between the subnetworks.Experimental results show that the method can effectively identify virus migration threshold and detect the trend of virus transmission in real time.

Key words: network security, Software Definition Network(SDN), network virus, community, random network, mobility ratio

摘要:

软件定义网络(SDN)提供了对网络的动态调控,但是安全性较差。为此,提出一种SDN下的动态随机网络模型。研究网络病毒随子网间节点迁移而扩散及爆发的过程,通过理论分析和数值模拟,发现网络病毒从源子网传播到目标子网的传播特性与子网间节点的迁移率相关。实验结果表明,该方法能有效找出病毒迁移阈值,并能实时发现病毒传播趋势。
