Study and Realization of DPDK-Based Intelligent Packet Parsing in Heterogeneous Networks

In the field of network security, packet parsing serves as a core technical foundation for network traffic monitoring, intrusion detection, and traffic management. Limited by the performance drawbacks of traditional packet capture mechanisms, this paper investigates intelligent packet parsing technology in heterogeneous network environments based on DPDK, proposing an algorithm capable of dynamically and efficiently parsing packets across standard Ethernet, PPPoE, VLAN, and nested VLAN networks with high accuracy. Experiments conducted using TCPReplay for traffic replay testing demonstrate that the algorithm maintains parsing accuracy and low latency even under 10 Gbps bandwidth and million-level concurrent flows. This research provides a scalable technical solution for real-time monitoring and analysis in highspeed, heterogeneous network environments.
