全IP宽带移动网络中基于分层P2P的协同防护机制

Corporate Defend Mechanism Based on Layered P2P in All IP Broadband Mobile Networks

针对基于IMS/SAE的全IP宽带移动网络架构的特点,分析研究了现有入侵检测技术的现状,提出了适用于全IP宽带移动网络的协同检测防护机制。该机制利用P2P技术实现了检测信息的协同交互和共享,通过建立分层的P2P网络架构减小了协同信息的资源占用率和传输时延,能够及时更新全IP宽带移动网络中的检测样本库,提高检测效率。

This paper analyses existing intrusion detection technology based on the features of the all-IP mobile broadband network architecture of IMS/SAE,and presents one collaborative detection defense mechanism applicable to all-IP broadband mobile network.The mechanism achieves synergistic interaction and sharing of detecting information using the P2P technology,reduces the resources utilization and transmission delay of coordination information through the establishment of tiered P2P network architecture,is able to update all-IP broadband mobile network testing sample library,and improves detection efficiency.
