高速网络环境下的数据采集技术

The Data Acquisition Technology Under the Gigabit Network Environment

近年来,网络带宽的飞速发展使得入侵检测系统、防火墙等网络安全产品在适应高速环境下的数据采集受到挑战。本文在对传统的数据采集进行深入研究的基础上,对NAPI与PF_RING技术进行了优化。实验结果表明,优化后NAPI与PF_RING技术能够对骨干网流量进行实时入侵检测系统的数据采集。

In recent years the rapid development of network bandwidth is challenged by making intrusion detection systems, firewalls and other network security products to adapt to the environment under high-speed data acquisition. This paper makes an in-depth study of data collection on the basis of the NAPI and PF_RING technology optimization and implementation,and the test results show that optimizing the NAPI and PF_RING technology can achieve the data acquisition of real-time traffic backbone network intrusion detection systems.
