[0002] Network transmission refers to the process of using a series of transmission media to communicate through circuit adjustments and changes based on network transmission protocols. Commonly used transmission media include twisted pair, coaxial cable, etc. Network protocols include the OSI (Open Systems Interconnection) seven-layer model, etc.

[0003] For network transmission between the host and the target network card, the next data can often be processed only after one data is processed. Data cannot be processed according to priority. Even if the software can process data according to priority, during the process of sending the current data, the currently arriving data with high real-time requirements and high priority must wait until the above current data is sent before it can be sent. At this time, the real-time nature of the currently arriving data cannot be guaranteed. Even if the software or hardware can send data with high priority or high real-time requirements based on interrupts, the interrupted transmission needs to be retransmitted with errors.

[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] For network transmission between the host and the target network card, the next data can often be processed only after one data is processed. Data cannot be processed according to priority. Even if the software can process data according to priority, during the process of sending the current data, the currently arriving data with high real-time requirements and high priority must wait until the above current data is sent before it can be sent, and the real-time nature of the currently arriving data cannot be guaranteed. Even if the software or hardware can send data with high priority or high real-time requirements based on interrupts, the interrupted transmission needs to be retransmitted with errors.

[0057] To this end, the embodiment of the present application proposes a network data packet processing solution, which can effectively reduce the time that large-capacity network data packets occupy the network link layer, thereby ensuring the real-time requirements of data transmission and reception.

[0058] The present application embodiment discloses a network data packet processing method, which is applied to a front-end device of a network link controller, see Figure 1 As shown, the method includes:

[0059] Step S11: Obtaining the packetization parameters and at least one network data packet sent by the host.

[0060] The protocol specifies the data format, transmission method, operation process and other details to ensure that the sender and receiver can understand and interpret the data. Take the OSI (Open Systems Interconnection) model as an example. The OSI model is a conceptual model used to describe the architecture of computer network protocols. It was proposed and defined by the International Organization for Standardization (ISO) in the 1980s. Figure 2 As shown in Figure 1, it divides the computer network communication process into seven different levels, namely: 1. Physical Layer; 2. Data Link Layer; 3. Network Layer; 4. Transport Layer; 5. Session Layer; 6. Presentation Layer; 7. Application Layer. Usually, data from the network layer (including the network layer) to the application layer are processed by software programs according to the protocol specifications of each layer. The data transmission and reception of the data link layer and the physical layer need to be processed by related hardware modules, such as the Ethernet network card, which is a hardware module that integrates data link layer and physical layer data processing.

[0061] Taking Ethernet network card as an example, the network card consists of three parts: the interface between the physical layer of the network card and the transmission medium (RJ45), the Ethernet data link controller, and the interface between the network card and the host. ( , ) interface, where the Ethernet data link controller is used to implement the transmission data encoding, reception data decoding, CRC (Cyclic Redundancy Check, cyclic redundancy check) generation and verification, etc. Figure 3 As shown in the figure, it can be seen that the process of Ethernet network card sending data is as follows: 1. The host sends the data to be sent through The interface writes it to the sending buffer; 2. The link controller chip will add the frame header information and generate a CRC check code to form an Ethernet data frame; 3. The physical layer interface controller controls the physical layer chip to convert the data into an electrical signal and send it out through the medium. The process of receiving data in the Ethernet network card: 1. The physical layer chip converts the valid electrical signal received by the medium into a digital signal and sends it to the Ethernet link controller chip; 2. The link controller chip checks whether the destination address of the frame is its own MAC address. If not, the data is discarded. If it is, it continues to receive data; 3. According to the frame header information, the full length data is received, and then the CRC check is performed. If everything is normal, the host is notified to take the data from the receiving buffer.

[0062] It can be seen from this that the traditional solution can only process the next sending request after one data sending request is processed, that is, after one Ethernet data frame is sent. It is impossible to process the high-priority sending request first when a high-priority sending request comes. Even if the software can process data according to priority, during the current data sending process, the currently arriving data with high real-time requirements and high priority must wait until the above-mentioned current data is sent before it can be sent. At this time, the real-time performance of the currently arriving data cannot be guaranteed. Even if the software or hardware can send data with high priority or high real-time requirements based on interrupts, the interrupted transmission needs to be retransmitted with errors.

[0063] To this end, this application adds a front-end hardware device in front of the Ethernet link controller chip. This device can be built-in or embedded in various embedded systems or host systems, and designs a protocol for the device to perform packet grouping processing on the sent and received data, realize the priority-based network data packet transmission and reception, and ensure the real-time requirements of data transmission and reception. Figure 4 As shown, the device includes a packet controller, a data packet sending buffer, a packet processing module, a sending module, a packet sending data buffer, a receiving module, a packet receiving data buffer, and a packet assembly processing module.

[0064] In this embodiment, the packetization parameters of the host are received by the packetization controller, and the packetization parameters are passed to the packetization processing module, wherein the packetization parameters include whether to packetize, the packetization length, etc.

[0065] Step S12: performing a packetization operation on the network data packets whose length is greater than a preset length threshold according to the priority information carried by the network data packets and the packetization parameters, so as to obtain a plurality of packetization data corresponding to each of the network data packets.

[0066] In this embodiment, at least one network data packet sent by the host is stored in a sending data packet buffer (ie, a first cache); each network data packet carries corresponding priority information.

[0067] Further, the packet processing module performs packet operations on the network data packets in the first cache whose length is greater than a preset length threshold according to the priority information and packet parameters carried by the network data packets. Figure 5 As shown in the figure, the priority of network data packet A is 5, and the priority of network data packet B is 3. The priority of network data packet B is higher than that of network data packet B, so network data packet B is first sub-packetized. It should be pointed out that a high priority indicates a high real-time performance. Assuming that the sub-packet length is 200 bytes, Figure 5 As shown, network data packet B and network data packet A are packetized in sequence. Specifically, network data packet A is packetized to obtain 200 a's, 200 b's, 200 c's and 148 d's, and network data packet B is packetized to obtain 200 1's, 200 2's and 10 3's.

[0068] Step S13: adding field information to each of the sub-packet data based on the target protocol; the field information includes the sorting information and the priority information of the sub-packet data in the corresponding network data packet, and the priority information of each of the sub-packet data divided from the same network data packet is the same.

[0069] In this embodiment, the sub-packet processing module adds field information to each sub-packet data based on the target protocol. The structural diagram of the target protocol is shown in Figure 6 As shown, it includes field 1: priority information, field 2: sub-packet data identifier, field 3: total number of sub-packet data, and field 4: sub-packet data number, wherein the sub-packet data identifiers of the sub-packet data divided from the same network data packet are the same, the total number of sub-packet data represents the number of sub-packet data divided from the same network data packet, and the sub-packet data number represents the order of the sub-packet data in the corresponding network data packet. Further, the number of the network data packets in the first cache is determined to obtain a first number.

[0070] Step S14: sending the sub-packet data to a network link controller according to the field information, so that the network link controller processes the sub-packet data to obtain processed sub-packet data.

[0071] In this embodiment, the packet data sent by the subpacket data buffer (second cache) is first stored to add the field information, and the sending module is used to determine whether the first quantity is 1. Further, if the first quantity is 1, the packet data in the second cache is directly sent to the network link controller. If the first quantity is not 1, the packet data is sent to the network link controller according to the field information.

[0072] Specifically, if the number of subpackets is not 1, the subpacket data in the second cache are sorted in order from high to low according to the priority information, and for the subpacket data with the same priority information, the subpacket data are sorted in order from small to large according to the subpacket data number to obtain the current sorting result. Further, the subpacket data in the second cache is sent to the network link controller according to the current sorting result, and it is determined in real time whether new subpacket data is stored in the second cache. If no new subpacket data is stored in the second cache, the subpacket data in the second cache continues to be sent to the network link controller according to the current sorting result. If new subpacket data is stored in the second cache, all current subpacket data in the second cache are re-sorted according to the priority information and the subpacket data number to obtain an updated sorting result. Finally, the current subpacket data in the second cache is sent to the network link controller according to the updated sorting result so that the network link controller processes the subpacket data.

[0073] That is to say, if the number of subpackets is not 1, each subpacket data is sorted in the order of priority information from high to low and the subpacket data number from small to large to obtain the current sorting result, and the subpacket data in the second cache is sent to the network link controller according to the current sorting result. During this process, this embodiment will continue to determine whether new subpacket data is stored in the second cache. If new subpacket data is stored in the second cache, the updated sorting result is obtained again, and the current subpacket data in the second cache is sent to the network link controller according to the updated sorting result.

[0074] See also Figure 5 , Figure 7 and Figure 8 As shown, different network data packets have different data packet identifiers. For example, the data packet identifier of network data packet A is 4567abcd, and the data packet identifier of network data packet B is 1234cdef. The packet processing module packets data packets A and B according to the set parameters and the packet protocol. Since the priority of data packet B is higher than that of A, data packet B is packetized first, and the packetized data is written into the sending packetized data buffer in sequence. After the sending module detects that there is packetized data in the sending packetized data buffer, it will traverse the priority fields of all the packetized data and give priority to sending the packetized data with high priority, such as the packetized data above. It will be sent to the link controller chip first. When the sending module sends the sub-packet data to the link control chip, the sub-packet processing module is also sub-packetizing the data packets in the sending data buffer. When the packet processing module writes the new higher priority packet data into the sending packet data buffer, at this time, based on the protocol priority, the sending module will send the packet data first. , Then send the sub-packet data .

[0075] Step S15: Acquire the processed subpacketized data sent by the network link controller.

[0076] In this embodiment, the receiving module The bus receives the processed data packet carrying the field information sent by the link controller chip, writes the processed data packet into the received subpacket data buffer (third cache), and notifies the packet assembly processing module of the number of received subpackets.

[0077] Step S16: performing a packetization operation on the processed sub-packetized data according to the field information to obtain packetized data so that the host can read the packetized data.

[0078] In this embodiment, when the packet assembly processing module detects that there is data in the received subpacket data buffer, it will traverse the "priority" field of all data packets and assemble the subpacket data with high priority first. Specifically, the packet assembly processing module assembles packets according to the "data packet identifier", "total number of data packets" and "current data packet number" fields of the protocol. After a complete data packet is assembled, it is written to the received data packet buffer (the fourth cache) so that the host can read the assembled data.

[0079] It should be pointed out that the present device and the packetization protocol are applied to the front stage of the network link controller, and can send large-capacity data packets in packets, effectively reducing the long-term occupation of the network link layer by large-capacity data transmission, and can achieve uniform length of packetized data, so that all data packets occupy the network link layer uniformly, and add priority-based sending and receiving control, so that data packets with high priority and high real-time requirements can be sent first, and can meet and be applied to various control fields with high real-time requirements, such as server management control, industrial control, etc. Further, the function of the receiver and the sender negotiating the length of the packetized data according to the real-time requirements can be added to the present device. Specifically, the sender and the receiver can calculate the delay time from the sender sending data to the receiver receiving data by sending a certain amount of test data, and the length of the packetized data can be inversely deduced according to the required minimum delay time, that is, setting the length of the packetized data can meet the requirements of the delay time for various data packets of both the sender and the receiver.

[0080] It can be seen that the present application proposes a network data packet processing method, which is applied to the front-stage device of a network link controller, including: obtaining the packetization parameters and at least one network data packet sent by the host; performing a packetization operation on the network data packet whose packet length is greater than a preset length threshold according to the priority information carried by the network data packet and the packetization parameters, so as to obtain a plurality of packetized data corresponding to each of the network data packets; adding field information to each of the packetized data based on the target protocol; wherein the field information includes the sorting information and the priority information of the packetized data in the corresponding network data packet, and the priority information of each of the packetized data divided from the same network data packet is the same; sending the packetized data to the network link controller according to the field information, so that the network link controller processes the packetized data to obtain processed packetized data; obtaining the processed packetized data sent by the network link controller; performing a packetization operation on the processed packetized data according to the field information to obtain packetized data, so that the host can read the packetized data. In summary, the present application adds a front-end hardware device to the network link controller, through which the large-capacity network data packets are processed by packetization, which effectively reduces the time that the large-capacity network data packets occupy the network link layer, and realizes the uniformity of the length of the packetized data, so that the time that all the packetized data occupy the network link layer is consistent, and because the present application does not need to use an interrupt mechanism to interrupt the data being sent, the present application does not need to perform error retransmission. Furthermore, the present application implements the control of the reception and transmission of network data packets based on the priority of the network data packets, so that the network data packets with high priority and high real-time performance are sent and processed first, ensuring the real-time requirements of data reception and transmission.

[0082] The data packet acquisition module 11 is used to acquire the packetization parameters and at least one network data packet sent by the host;

[0083] The subpacketization module 12 is used to perform a subpacketization operation on the network data packets whose data packet length is greater than a preset length threshold according to the priority information carried by the network data packets and the subpacketization parameters, so as to obtain a plurality of subpacketized data corresponding to each of the network data packets; and to add field information to each of the subpacketized data based on the target protocol; wherein the field information includes the sorting information and the priority information of the subpacketized data in the corresponding network data packet, and the priority information of each of the subpacketized data divided from the same network data packet is the same;
