[0045] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the embodiments of the present application should fall within the scope of protection of the embodiments of the present application.

[0046] The specific implementation of the embodiment of the present application is further explained below in conjunction with the accompanying drawings of the embodiment of the present application.

[0047] The present application embodiment provides a DPU data transmission method, which is applied to Figure 1 The DPU shown in the figure includes a control unit, a media access controller and a communication main line. One end of the control unit is connected to the media access controller, and the other end is connected to the communication main line. The DPU is connected to the CPU through the communication main line. Furthermore, the DPU is also connected to a storage device, which is a storage device external to the DPU, which can be specifically DDR, and the communication main line can be specifically PCIe.

[0048] Furthermore, the DPU data transmission method provided in the embodiment of the present application has the following specific steps: Figure 2 As shown, the method includes:

[0049] S201, when the media access controller receives a transaction market data packet, the control unit transmits the transaction market data packet to the CPU through the communication main line, and writes the log data to the storage device.

[0050] In the embodiment of the present application, when the market server transmits the transaction market data packet to the DPU, when the media access controller of the DPU receives the transaction market data packet, the control unit immediately transmits the transaction market data packet to the CPU through the communication main line, and completes the transmission of the transaction market data packet with low latency. At the same time, the control unit also collects the log data of the DPU during the transmission of the transaction market data packet through the communication main line, and writes the collected log data into the storage device connected to the DPU.

[0051] Specifically, the log data in the embodiment of the present application may include the parsing time when the DPU parses the transaction quotation data packet, the status of the DPU, etc.

[0052] S202: The control unit detects the working status of the media access controller.

[0053] In the embodiment of the present application, during the process of transmitting the transaction quotation data packet through the communication main line, the control unit detects the working state of the media access controller to determine whether the transaction quotation data packet has been transmitted. Specifically, the working state of the media access controller may include idle and non-idle. If the control unit determines that the working state of the media access controller is idle, the control unit determines that the transmission of the transaction quotation data packet is completed. If the control unit determines that the working state of the media access controller is non-idle, the control unit determines that the transmission of the transaction quotation data packet is not completed.

[0054] S203: If the control unit determines that the working state of the media access controller is idle, the control unit transmits the log data to the CPU through the communication main line.

[0055] In an embodiment of the present application, after detecting the working status of the media access controller, if the control unit determines that the working status of the media access controller is idle, the control unit determines that the transmission of the transaction quotation data packet is completed, and then the control unit determines that the communication main line is idle at this time, and then the control unit transmits the log data stored in the storage device to the CPU through the communication main line to complete the data transmission.

[0056] The DPU-based data transmission method provided in the embodiment of the present application, when the media access controller receives the transaction quotation data packet, the control unit transmits the received transaction quotation data packet to the CPU, and writes the log data generated by the DPU in the process of transmitting the transaction quotation data packet to the storage device, and further, detects the working state of the media access controller, and further, the working state of the media access controller is idle, and the log data is transmitted to the CPU through the communication main line. In the embodiment of the present application, when the media access controller receives the transaction quotation data packet, the control unit transmits the transaction quotation data packet to the CPU through the communication main line, so that the transaction quotation data packet can monopolize the communication main line, and then the transaction quotation data packet can be transmitted to the CPU with low delay, and further, when the media access controller is idle, the log data stored in the storage device is transmitted to the CPU, which can avoid the problem of delay in the transmission of the transaction quotation data packet caused by the log data occupying the communication main line.

[0057] Furthermore, the present application embodiment provides another structural diagram of a DPU, as shown in FIG. Figure 3As shown, the DPU also includes a first timer, one end of the first timer is connected to the media access controller, and the control unit is specifically connected to the media access controller through the other end of the first timer. The first timer is used to reset and count each time the media access controller receives a transaction quotation data packet. Specifically, when the media access controller receives the first quotation transaction data packet, the first timer is reset and starts counting. When the media access controller receives the second quotation transaction data packet, the first timer is reset again and starts counting again.

[0058] Further, the first timer has a first threshold, and when the timing reaches the first threshold, the first timer transmits the first timing information to the control unit. Specifically, the first threshold may be 20ms, and when the timing reaches 20ms, the first timer transmits the first timing information to the control unit.

[0059] Further, the detection of the space status of the media access controller in the embodiment of the present application may include the following steps:

[0060] S201: A control unit detects whether first timing information transmitted by a first timer is received.

[0061] In an embodiment of the present application, when the control unit detects the working status of the media access controller, the control unit detects the working status of the media access controller through a first timer. Specifically, the first timer is reset and counts each time the media access controller receives a transaction quotation data packet, and when the timing reaches a first threshold, the first timing information is transmitted to the control unit. Then, the control unit can detect the working status of the media access controller by detecting whether it has received the first timing information transmitted by the first timer.

[0062] S202: If the control unit receives the first timing information, it determines that the working state of the media access controller is idle.

[0063] In an embodiment of the present application, if the control unit detects that it has received the first timing information, the control unit determines that the media access controller has not received a new transaction quotation data packet for a long time, and then the control unit determines that the media access controller is idle. Further, the control unit determines that the transaction quotation data packet is transmitted, thereby determining that the communication main line is not occupied and is also in an idle state.

[0064] S203: If the control unit does not receive the first timing information, it determines that the working state of the media access controller is non-idle.

[0065] In an embodiment of the present application, if the control unit detects that it has not received the first timing information, the control unit determines that the media access controller is in a state of receiving a transaction quotation data packet, and then the control unit determines that the media access controller is non-idle. Further, the control unit determines that the transmission of the transaction quotation data packet is not completed, thereby determining that the communication main line is occupied and is also non-idle.

[0066] In the embodiment of the present application, the first timer is reset and counted each time the media access controller receives a transaction quotation data packet, so that the control unit can accurately determine the working status of the media access control, so that the control unit can determine whether to transmit log data according to the working status of the media access controller, and thus can avoid transmitting log data when the communication main line is occupied, thereby ensuring that the transaction quotation data packet can monopolize the communication main line during transmission.

[0067] Furthermore, in the embodiment of the present application, the log data is transmitted to the CPU via the communication main line, which may include the following steps:

[0068] S2031: The control unit divides the log data into a plurality of log sub-data according to a preset number of bytes.

[0069] In the embodiment of the present application, when the control unit transmits the log data, the control unit first obtains a preset number of bytes, and divides the log data into a plurality of log sub-data using the preset number of bytes. Specifically, the preset number of bytes may be 1500 bytes, or other numbers.

[0070] S2032: The control unit encapsulates each log sub-data respectively to generate multiple log data packets.

[0071] In the embodiment of the present application, after the control unit divides the log data into a plurality of log sub-data, the control unit encapsulates each log sub-data respectively to generate a plurality of log data packets.

[0072] S2033, transmit the log data packet to the CPU through the communication main line.

[0073] In the embodiment of the present application, after generating multiple log data packets, the control unit transmits each log data packet to the CPU in sequence through the communication main line to complete the transmission of the log data.

[0074] The control unit of the embodiment of the present application can conveniently transmit log data by dividing the log data into log data packets for transmission.

[0075] For further information, please refer to Figure 3As shown, the DPU of the embodiment of the present application also includes a second timer, one end of the second timer is connected to the first timer, and the other end is connected to the control unit, and is used to reset and time when the control unit starts to transmit the log data packet of the log data. Specifically, the second timer is reset and starts timing when the control unit starts to transmit the log data packet of the log data, and when the timing reaches the second threshold, the second timer transmits second timing information to the control unit, and the second timing information is used to instruct the control unit to stop transmitting the log data packet of the log data.

[0076] Further, the second timer has a second threshold, and when the timing reaches the second threshold, the second timer transmits the second timing information to the control unit. Specifically, the second threshold may be 480ms, and when the timing reaches 480ms, the second timer transmits the second timing information to the control unit.

[0077] Furthermore, the DPU-based data transmission method of the embodiment of the present application may further include the following steps:

[0078] S203: The control unit detects whether second timing information transmitted by a second timer is received.

[0079] In an embodiment of the present application, when the control unit transmits a log data packet of log data through the communication main line, the control unit controls the transmission time of the log data through the second timer. Specifically, the second timer is reset and starts timing when the log data packet of log data starts to be transmitted, and when the timing reaches a second threshold, the second timing information is transmitted to the control unit. Then, the control unit can control the transmission time of the log data by detecting whether it has received the second timing information transmitted by the second timer, thereby avoiding the log data occupying the communication main line for a long time, and thereby avoiding the transaction quotation data packet from being unable to be transmitted to the CPU in time.

[0080] S204: If the control unit receives the second timing information, it detects whether the log data transmission is completed.

[0081] In the embodiment of the present application, when the control unit receives the second timing information, the control unit determines that the log data occupies the communication main line for a maximum time and needs to stop transmitting the log data, and then the control unit detects whether the log data has been transmitted. Specifically, the control unit can detect the number of log data packets that have been transmitted to determine whether the log data has been transmitted.

[0082] S205: If the control unit determines that the transmission of the log data is not completed, it stops transmitting the log data and transmits the received transaction quotation data packet.

[0083] In the embodiment of the present application, if the control unit determines that the log data transmission is not completed, it stops transmitting the log data and transmits the received transaction quotation data packet, so that the transaction quotation data packet can be transmitted to the CPU in a timely manner.

[0084] The embodiment of the present application uses a second timer to time the transmission time of the transmission log data. When the transmission time of the transmission log data reaches a second threshold and the transmission of the log data is not completed, the transmission of the log data is stopped and the received transaction quotation data packet is transmitted, so that the transaction quotation data packet can be transmitted to the CPU in a timely manner.

[0085] Furthermore, the DPU-based data transmission method of the embodiment of the present application may also include the following steps:

[0086] S206: If the transmission of the log data packet is stopped during the transmission of the log data packet, the control unit detects whether the transmission of the first log data packet being transmitted is completed.

[0087] In an embodiment of the present application, if the control unit stops transmitting the log data during the process of transmitting the log data packet, the control unit detects whether the first log data packet being transmitted has been transmitted. Specifically, the control unit can determine whether the first log data packet has been transmitted based on the number of bytes transmitted.

[0088] S207: If the transmission of the first log data packet is not completed, the transmission of the first log data packet is stopped, and the control unit adds an error mark in the first log data packet.

[0089] In the embodiment of the present application, if the control unit determines that the transmission of the first log data packet is incomplete, the control unit immediately stops the transmission of the first log data packet and adds an error mark in the first log data packet to instruct the CPU to delete the first log data packet.

[0090] S208: When the control unit re-receives the first timing information, it re-transmits the first log data packet through the communication main line.

[0091] In the embodiment of the present application, after the transmission of the transaction quotation data packet is completed, that is, when the control unit receives the first timing information again, the control unit retransmits the first log data packet to the CPU through the communication main line.

[0092] In the embodiment of the present application, the control unit adds an error identifier in the first log data packet when the transmission of the first log data packet is not completed, so that the CPU can accurately identify the error packet, thereby ensuring the integrity of the log data. Furthermore, the control unit can ensure that the log data packets transmitted to the CPU are all completed data packets by retransmitting the first log data packet through the communication main line when the first timing information is re-received, thereby further ensuring the integrity of the log data.

[0093] Furthermore, the embodiment of the present application provides another data transmission method based on DPU, the specific steps are as follows: Figure 4 As shown, including:

[0094] When the media access controller receives a transaction quotation data packet, the control unit transmits the transaction quotation data packet to the CPU through the communication main line, and writes the log data to the storage device. The first timer is reset and counts each time the media access controller receives a transaction quotation data packet, and when the timing reaches a first threshold, the first timing information is transmitted to the control unit.

[0095] If the control unit detects that it has received the first timing information, determines that the media access controller is idle, obtains a preset number of bytes, and uses the preset number of bytes to divide the log data into multiple log sub-data, the control unit encapsulates each log sub-data respectively to generate multiple log data packets. Furthermore, the control unit transmits each log data packet to the CPU in turn through the communication main line to complete the transmission of the log data.

[0096] The second timer is reset and starts timing when the control unit starts to transmit the log data packet of the log data, and when the timing reaches the second threshold, the second timer sends second timing information to the control unit. If the control unit receives the second timing information, it detects whether the log data transmission is completed. If the control unit determines that the log data transmission is not completed, it stops transmitting the log data and transmits the received trading quotation data packet.

[0097] At the same time, if the transmission of the log data packet is stopped during the transmission of the log data packet, the control unit detects whether the first log data packet being transmitted is completed. If the control unit determines that the transmission of the first log data packet is not completed, the control unit immediately stops the transmission of the first log data packet and adds an error mark in the first log data packet to instruct the CPU to delete the first log data packet.

[0098] When the control unit receives the first timing information again, the control unit retransmits the first log data packet to the CPU through the communication main line.

[0099] Furthermore, the embodiment of the present application provides a data transmission device based on a DPU, which is applied to a control unit of the DPU, and the DPU is also connected to a storage device, specifically Figure 5 As shown, the device comprises:

[0100] The first transmission module 501 is used to transmit the transaction market data packet to the CPU through the communication main line when the media access controller receives the transaction market data packet, and write the log data to the storage device, wherein the log data is generated by the DPU during the transmission of the transaction market data packet;

[0101] A detection module 502 detects the working status of the media access controller;

[0102] The second transmission module 503 is used to transmit the log data to the CPU through the communication main line if the working state of the media access controller is idle.

[0103] Furthermore, the detection module 502 of the embodiment of the present application is also used to detect whether the first timing information transmitted by the first timer is received, wherein the first timing information is transmitted to the control unit when the timing time of the first timer reaches a first threshold; if the first timing information is received, it is determined that the working state of the media access controller is idle; if the first timing information is not received, it is determined that the working state of the media access controller is non-idle.

[0104] Furthermore, the second transmission module 503 of the embodiment of the present application is also used to divide the log data into multiple log sub-data according to a preset number of bytes; encapsulate each log sub-data respectively to generate multiple log data packets; and transmit the log data packets to the CPU through the communication main line.

[0105] Furthermore, the DPU-based data transmission device of the embodiment of the present application may also include a timer detection module, which is specifically used to detect whether second timing information transmitted by a second timer is received, wherein the second timing information is transmitted to the control unit when the timing time of the second timer reaches a second threshold; if the second timing information is received, it is detected whether the log data transmission is completed; if the log data transmission is not completed, the log data transmission is stopped, and the received transaction quotation data packet is transmitted.

[0106] Furthermore, the DPU-based data transmission device of the embodiment of the present application may also include a judgment module, which is specifically used to detect whether the first log data packet being transmitted is completed if the transmission of log data is stopped during the transmission of the log data packet; if the transmission of the first log data packet is not completed, stop transmitting the first log data packet and add an error mark to the first log data packet, wherein the error mark is used to instruct the CPU to delete the first log data packet trading quotation data packet.

[0107] Furthermore, the second transmission module 503 of the embodiment of the present application may also be configured to retransmit the first log data packet through the communication main line when the first timing information is re-received.
