| 摘 要： | 针对蠕虫病毒提出了易感主机有常数输入并具有标准传染率的SIRS传播模型，考虑蠕虫病毒在传播期间主机总数的动态变化性，应用微分方程定性与稳定性理论对该模型进行分析, 讨论了不同因素对蠕虫病毒控制的影响。并利用Abilene网络分析了网络拓扑对病毒传播速率的影响。最后，通过CAIDA提供的蠕虫数据对该模型进行了检验。

| Abstract: | According to worm propagation,a SIRS propagation model of susceptible hosts with constant recruitment and standard incidence rate is proposed. Considering that the total host count is dynamically changed during the propagation, the qualitative and stability theory of the differential equation is applied to analyze the model. Not only the propagation regularity of worm virus but also the effects of different factors on the worm virus control are discussed. And the Abilene network is used to analyze the effects of network topology on worm propagation rate. At last, the worm data provided by CAIDA are used to test the model. |
