The Comparison and Verification of Some Efficient Packet Capture and Processing Technologies

Packet capture technology is the basis for network data analysis and processing. The rapid development of network applications, the speed of network transmission, and the speedy increase in the number of network users put forward higher requirements for packet capture technology. Some high-performance network packet capture technologies come into being. This paper first analyzes the inherent defects of the traditional Linux data capture method, and then introduces and analyzes the advantages and disadvantages of the current high-performance packet capture technologies and framework from the technical principle, application flow, packet capture rate and resource occupancy.
