Capture packets have a wide range of use in the network data analysis,intrusion detection systems,firewalls and other network monitoring or defense systems.Face the Gigabits network environment of class high-speed,the impact of high-speed data stream packet loss caused by an impact on data capture performance.This paper compares a variety of features to enhance data capture technology,through NAPI and PF_RING to achieve conflict-free access to shared resources.Experiments show that compared with the Libpcap packet capture capabilities significantly enhanced.
