摘　　要：结合结构化P2P网络拓扑和主动型蠕虫的特征,考虑网络中节点的在线率对蠕虫传播的影响,弥补了现有模型忽略网络中节点在线数量变化的不足,提出基于节点在线率的蠕虫传播模型,与双因素模型相比较,该模型能更客观地反映现实中蠕虫传播情况。Combining the features of structured P2P network topology and active worms, this paper propose a propagation model which compensates for the existing models ignoring the change of host number online and takes node rate online into consideration. Simulation result demonstrates, comparing with the propagation model of Two-Factor, the model based on node rate online is more suitable for the propagation characteristics of active worm in structured P2P network.
