Real-time Ethernet fieldbus data packet processing method based on AFXDP

The invention relates to a real-time Ethernet fieldbus network data packet processing method based on an AFXDP, relates to the technical field of numerical control, in particular to the technical field of real-time Ethernet fieldbuses, and particularly relates to the real-time Ethernet fieldbus network data packet processing method based on the AFXDP. The method comprises the following steps: firstly, analyzing a transmission path of a real-time Ethernet fieldbus data packet in a native network card driver, and establishing a capture point of the real-time Ethernet fieldbus data packet at an entrance of the network card driver; then, analyzing the characteristics of the data packet at the capture point, and establishing an AFXDP-based data packet capture and forwarding method; and finally, according to the bus protocol type to which the data packet belongs, designing an analysis processing method of the data packet in the real-time Ethernet bus component in the user space. 本发明涉及一种基于AF_XDP的实时以太网现场总线网络数据包处理方法，涉
