The embodiment of the invention provides a method for receiving and transmitting a network data packet, network equipment and a communication system, and the method for receiving and transmitting the network data packet comprises the following steps: a fast core network protocol stack obtains a data packet from a network card queue, and sends the data packet to a slow core protocol stack; the data packet is matched with a preset strategy at the slow core network protocol stack, if the matching is successful, uploading the data packet to an annular queue, otherwise, sending the data packet to a network card queue; the data packet is read from the annular queue through the monitoring process, a judgment result for the data packet is obtained, a judgment result mark is added to the data packet, and the data packet containing the judgment result is sent to the annular queue; and if the fast core confirms that the data packet is marked with the judgment result mark, the data packet is sent to a slow core, and the slow core determines to discard the data packet or send the data packet to the network card queue according to the judgment result.
Description
technical field [0001] The present application relates to the field of sending and receiving data packets, and specifically, the embodiments of the present application relate to a method for sending and receiving network data packets, a network device, and a communication system. Background technique [0002] Network security devices are usually deployed in a serial manner to monitor data traffic, analyze traffic characteristics, and discard or forward data packets according to the analysis results. Therefore, the packet forwarding efficiency of network security devices is an important factor affecting the speed of network traffic. . [0003] The application process receives data packets through the listening socket, and the socket option can be added to filter the data packets. The processing logic of this processing method is cumbersome and cannot meet the network performance requirements of high-performance network devices. [0004] Therefore, how to increase the sending...
