摘　　要：由于分布式内容分发网(CDN)技术的广泛应用,网站域名所对应因特网协议(IP)地址可能为多个,这给骨干网流量检测系统的实时检测控制提出了更高的要求。骨干网络流量中实时提取域名系统(DNS)响应消息并从中获取域名和IP地址,同时迅速更新到流量检测系统。基于Octeon多核网络处理器的高速处理能力,设计并实现了流量检测系统中的快速DNS检测与联动模块,并通过在骨干网链路中实际测试运行确保了系统的正确性和稳定性。Because content delivery network （CDN） technology is widely used,the Internet protocol （IP） address that network station domain name corresponds to may be multiple,which puts for- ward higher requirement to the real-time detection and control of flow detection system in the backbone network. In the flow of backbone network, the domain name system （DNS） responding message is extracted in real time and the domain name and IP address are fetched,at the same time the flow detection system is rapidly updated. This paper designs and realizes the rapid DNS detec- tion and joint action model in flow detection system based on the high-speed processing capability of Octeon multi-core network processor,and guarantees the correctness and stability of the system through the practical detection and running in the backbone network link.
