[0033] It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0034] The present invention provides a data processing method, which is applied to a data processing device. Figure 1 A flow chart of a data processing method provided in an embodiment of the present application is shown as follows: Figure 1 As shown, the data processing method may include:

[0035] S101. When a first data packet is received, determine a first data stream corresponding to the first data packet and a first data packet header feature of the first data packet.

[0036] In an embodiment of the present application, upon receiving a first data packet, the data processing device determines a first data stream corresponding to the first data packet and a first data packet header feature of the first data packet.

[0037] A data processing method proposed in an embodiment of the present application can be applied to scenarios where data packets are sent and received.

[0038] It should be noted that Figure 2 This is a schematic diagram of an exemplary data processing device structure provided in an embodiment of the present application, as shown in FIG. Figure 2 As shown, the data processing device includes an FPGA and a system-on-chip (SOC), and the SOC specifically includes a data plane development kit (DPDK), an application module, a data packet analysis module, and a pre-packet processing list module, wherein the FPGA is used to receive incoming data packets and determine a packet processing method for the data packets; the DPDK is used to assist the FPGA in sending data packets to the application module of the SOC; the application module is used to receive data packets sent by the FPGA; the data packet analysis module is used to parse the received data packets to obtain data packet header features, and then determine the traffic type of the data flow to which the data packet belongs based on the data packet header features, and send it to the pre-packet processing list orchestration module; the pre-packet processing list orchestration module is used to determine the corresponding packet processing list based on the traffic type, and send it to the FPGA, so that the FPGA can determine the packet processing method for the data packet based on this packet processing list.

[0039] It should be noted that when the first data packet flows into the data processing device, it first flows into the FPGA. After determining the first data stream corresponding to the first data packet and the first data packet header characteristics of the first data packet, the FPGA needs to determine whether the first data packet is the first data packet in the first data stream, and then choose whether to send the first data packet to the SOC for processing based on the judgment result.

[0040] It should be noted that the data packet header features include: a five-tuple, a transport layer protocol flag, an application layer protocol, etc.; among them, the five-tuple includes: a source Media Access Control Address (MAC) address, a destination MAC address, a source Internet Protocol (IP) address, a destination IP address, and a communication protocol.

[0041] S102: If it is determined that the first data packet is not the first data packet in the first data stream, search for a first packet processing list corresponding to the first data stream from a correspondence between preset data streams and preset packet processing lists.

[0042] In an embodiment of the present application, when the data processing device determines that the first data packet is not the first data packet in the first data stream, it searches for the first packet processing list corresponding to the first data stream from the correspondence between the preset data stream and the preset packet processing list.

[0043] In an embodiment of the present application, the preset packet processing list in the correspondence between the preset data stream and the preset packet processing list is determined according to the first data packet in the preset data stream corresponding to the preset packet processing list; a group of data packet header features and a group of packet processing methods are stored in the first packet processing list, and each data packet header feature in the group of data packet header features corresponds to a packet processing method.

[0044] It should be noted that, since the first packet processing list is determined based on the first data packet in the first data stream, the first data packet of the first data stream needs to be processed first; specifically, if it is determined that the first data packet is the first data packet in the first data stream, the first traffic type corresponding to the first data stream is determined based on the first data packet header characteristics, and the first packet processing list corresponding to the first traffic type is searched from the correspondence between the preset traffic type and the preset packet processing list; the correspondence between the first data stream and the first packet processing list is added to the correspondence between the preset data stream and the preset packet processing list; and the first packet processing method corresponding to the first data packet header characteristics is searched from the first packet processing list, so as to perform packet processing on the first data packet based on the first packet processing method.

[0045] It should be noted that, when the FPGA determines that the first data packet is the first data packet in the first data stream, it needs to send the first data packet to the SOC for processing.

[0046] It should be noted that if Figure 2 As shown in the figure, FPGA uses DPDK to send the first data packet to SOC. Since DPDK can directly bypass the kernel space of SOC and send the first data packet to the user space of SOC, that is, the application module, it can reduce the frequency of CPU interruption and memory copy, and improve the rate of data packet upload.

[0047] It should be noted that before using DPDK to send the first data packet from the FPGA to the SoC, you need to first create the DPDK environment, set up large page memory of no less than 2MB, unbind the Peripheral Component Interconnect (PCI) device responsible for sending data packets in the SmartNIC from the control of the Linux operating system, and rebind the DPDK ibg_uio module as a driver.

[0048] It should be noted that, since the FPGA does not send the first data packet header feature corresponding to the first data packet when sending the first data packet to the SOC, the SOC needs to parse the first data packet when receiving the first data packet to obtain the first data packet header feature of the first data packet, and this process is implemented by the data packet analysis module in the SOC, such as Figure 2 As shown, the data packet analysis module is set between the DPDK and the application module in the SOC, and is responsible for extracting the data packet header features and determining the traffic type of the data flow based on the data header features.

[0049] It should be noted that the traffic type is a character string used to assist in arranging the pre-packet processing list. It is usually described by the application layer protocol name of the data packet. The traffic types include: Secure Shell Protocol (SSH) connection, File Transfer Protocol (FTP) connection, remote control Telnet protocol connection, Hypertext Transfer Protocol (HTTP) access, Secure Hypertext Transfer Protocol (HTTPs) access, etc.; the specific traffic type can be specified according to actual conditions, and the embodiments of this application do not make specific limitations here.

[0050] In the embodiment of the present application, after the data packet analysis module determines the first traffic type of the first data flow, such as Figure 2 As shown, the first traffic type is sent to the pre-packet processing list arrangement module, and the pre-packet processing list arrangement module can obtain the first packet processing list corresponding to the first traffic type by searching the correspondence between the preset traffic type and the preset packet processing list.

[0051] In an embodiment of the present application, the correspondence between the preset traffic type and the preset packet processing list is generated before searching for the first packet processing list corresponding to the first traffic type from the correspondence between the preset traffic type and the preset packet processing list. Specifically: the preset traffic type, a set of data packet header features and a set of packet processing methods corresponding to each preset traffic type are obtained; a preset packet processing list is generated based on a set of data packet header features and a set of packet processing methods corresponding to each preset traffic type; and a correspondence between the preset traffic type and the preset packet processing list is generated based on the preset traffic type and the preset packet processing list.

[0052] It should be noted that each traffic type has a corresponding packet processing list, which stores the packet processing method corresponding to this traffic type.

[0053] It should be noted that the packet processing method can be forwarding to a specified device or port, etc. The specific processing method can be specified according to actual conditions, and the embodiment of this application does not make specific limitations here.

[0054] It should be noted that, in actual applications, the data packet header features and the corresponding packet processing methods can be customized, and a preset packet processing list can be generated based on them to process the incoming data packets.

[0055] It should be noted that the process of the SOC determining the first packet processing list according to the first traffic type is implemented by the pre-packet processing list arrangement module in the SOC, such as Figure 2 As shown, the pre-packet processing list orchestration module is set between DPDK and the application module in the SOC, and is responsible for determining the corresponding packet processing list according to different traffic types.

[0056] S103: Search the first packet processing method corresponding to the first data packet header feature in the first packet processing list; and perform data packet processing on the first data packet based on the first packet processing method.

[0057] In an embodiment of the present application, after finding the first packet processing list, the data processing device searches the first packet processing method corresponding to the first data packet header feature from the first packet processing list; and performs packet processing on the first data packet based on the first packet processing method.

[0058] It should be noted that after finding the first packet processing list, the SOC determines the first packet processing method corresponding to the first data packet from the first packet processing list, and then sends the first data stream, the first packet processing list and the first packet processing method to the FPGA. After receiving the first data stream, the first packet processing list and the first packet processing method, the FPGA first processes the first data packet based on the first packet processing method, and then adds the correspondence between the first data stream and the first packet processing list to the correspondence between the preset data stream and the preset packet processing list. When the next data packet of the first data stream is received, the first packet processing list is directly obtained from the correspondence between the preset data stream and the preset packet processing list, and then the next data packet of the first data stream is processed according to the packet processing method of the next data packet in the first packet processing list.

[0059] It should be noted that, since the FPGA sends the first data packet in the first data stream to the SOC and obtains the first packet processing list corresponding to the first data stream, in the embodiment of the present application, the FPGA can determine the first packet processing method for the first data packet by searching the first packet processing list corresponding to the first data stream when it determines that the first data packet is not the first data packet in the first data stream.
