摘要
为降低良性蠕虫网络带宽消耗和提高传播速度,提出基于分层叠加网的良性蠕虫扩散模型—HOPM(Hierarchy Over-lay Propagation Model)和基于周期性反馈策略的自适应良性蠕虫传播控制算法—FBSP(Feed Back Self-adapting Propagation Algorithm).分层叠加网模型具有逼近物理网结构、自适应网络变化的特点;FBSP算法跟踪蠕虫与良性蠕虫的交互过程,根据周期性反馈信息实时调整良性蠕虫的传播范围和策略来控制其网络带宽消耗.仿真实验表明在宏观网络环境下,基于分层叠加网的良性蠕虫扩散的通信负荷为基于Landmark叠加网模型的30%-50%.
In order to reduce the influence on network and improve the speed during the antiworm propagating, a hierarchy overlay propagation model （HOPM） and a propagating algorithm which is based on periodical feedback self-adapting technology algorithm（FBSP） are proposed. The hierarchy propagation model has the following characteristics： manageable, approaching the physical network which is based on, and adapting frequent changes of the physical network. The FBSP algorithm traces the reciprocity processing of worms and antiworms, adjusts the antiworm propagating ranges and policies in real time to control the consumption of network bandwidth. The simulated result shows, while the network is large enough, the communication load of the antiworm propagating in HOPM model is only about 30%--50% of the one in a Landmark model.
