[0053] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.
[0054] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.
[0055] The main solution of the embodiment of the present application is: obtain a data reception signal, and obtain a target data packet based on the data reception signal; parse the target data packet to obtain a data priority; store the target data packet in a target storage space according to the data priority; and transmit the target data packet in the target storage space based on the data processing priority of the target storage space.
[0056] In this embodiment, for the convenience of description, the following description is made by taking the identification of the kernel data transmission device as the execution subject.
[0057] As existing technologies develop rapidly with new technologies and applications such as artificial intelligence and smart cockpits, the intelligence of automobiles continues to improve. Advanced driver assistance functions such as adaptive cruise control and automatic emergency braking are increasingly used in smart connected cars, which facilitates people's daily travel and also demonstrates the great potential of fully autonomous driving in the future in reducing safety accidents, improving traffic efficiency and enhancing driving experience. However, with the widespread deployment of intelligent driving technology in automobiles, intelligent driving carries more and more functions, and more and more data is transmitted between various functional management systems, which also leads to a huge amount of data to be processed by the intelligent driving center and lower processing efficiency.
[0058] The present application provides a solution, which parses the target data packet received by the kernel to obtain the priority of the target data packet, stores the data packet in a storage space corresponding to the priority based on the priority of the data packet, transmits the data packets in the storage space in sequence based on the priority of each storage space, and processes different data packets in sequence according to the priority of the data, improves the network transmission efficiency of the data based on the priority of the kernel processing the data, and transmits the data over the network more efficiently.
[0059] It can be seen from the above embodiments that the present application discloses a kernel data transmission method, device, equipment and storage medium, which relates to the field of data processing technology, and discloses: obtaining a data reception signal, and obtaining a target data packet based on the data reception signal; parsing the target data packet to obtain a data priority; storing the target data packet in a target storage space according to the data priority; transmitting the target data packet in the target storage space based on the data processing priority of the target storage space; the method parses the target data packet received by the kernel to obtain the priority of the target data packet, stores the data packet in a storage space corresponding to the priority based on the priority of the data packet, and transmits the data packets in the storage space in sequence based on the priority of each storage space, so as to realize sequential processing of different data packets according to the data priority, improve the network transmission efficiency of the data based on the priority of the kernel processing data, and transmit the data over the network more efficiently.
[0060] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a kernel data transmission device, etc. The following takes the kernel data transmission device as an example to illustrate this embodiment and the following embodiments.
[0061] Based on this, the present application embodiment provides a kernel data transmission method, referring to Figure 1 , Figure 1 This is a flowchart of the first embodiment of the kernel data transmission method of the present application.
[0062] In this embodiment, the kernel data transmission method includes steps S10 to S40:
[0063] Step S10, acquiring a data receiving signal, and obtaining a target data packet based on the data receiving signal.
[0064] It should be noted that the operating system widely used in the field of intelligent driving is Linux. The following is an introduction to the network data transmission process of the Linux operating system. Figure 2 As shown, Figure 2 The complete path of the message sent from the client to the server is that the client first creates a socket, transmits it through the network protocol, and then transmits the data to the kernel driver through skb. The kernel driver then sends the data to the device for processing, and then transmits it between network devices until it is applied to the client. This embodiment is based on Figure 2 The kernel driver is used to optimize network transmission efficiency.
[0065] It is understandable that the data receiving signal may be a data receiving message, and when the kernel receives the message, it is ready to receive a data packet to be transmitted through the kernel.
[0066] It can be understood that the target data packet is a data packet received by the kernel and to be stored in the storage space waiting to be sent.
[0067] In the specific implementation, the kernel data receiving process can refer to Figure 3 In the figure, the message triggers the kernel driver to receive the packet through an interrupt.
[0068] It should be noted that obtaining the target data packet based on the data reception signal may be firstly copying the data to be transmitted through the kernel from the network device to the CPU memory to obtain the target data packet.
[0069] Step S20, parsing the target data packet to obtain data priority.
[0070] It should be noted that the target data packet includes a target address, a source address and other information, and the priority of the data is obtained according to the source address obtained by parsing the target data packet.
[0071] In the specific implementation, the step of receiving the target data packet can refer to Figure 4 In the figure, skb represents a data packet. Figure 4 For example, the data packet includes the data header, the data itself, the data information, the data tail, etc.; the network message of the data itself includes the target MAC address (target address), the source MAC address (source address, that is, the address where the target data packet is sent to the kernel) and other information.
[0072] It should be noted that the data priority of the target data packet is related to the source address of the target data packet, that is, the priority of the source address in the preset address priority list can be understood as the priority of the target data packet.
[0073] It should be emphasized that the preset address priority list may include the priority of each source address.
[0074] In a specific implementation, the preset address priority list can be a description file host_weight added under / etc, and the description file host_weight includes the mac addresses of allowed communication devices and the priority of each allowed communication device (ie, the priority of each mac address).
[0075] Step S30, storing the target data packet into a target storage space according to the data priority, wherein the target storage is controlled to be any one of a plurality of preset storage spaces.
[0076] It should be emphasized that when setting and dividing the priority of transmission through the kernel, there are three priorities: the priority of the data packet, the priority of the device allowed to communicate, and the priority of each preset storage space.
[0077] It can be understood that the priority of the data packet is the same as the source address of the data in the data packet (that is, the priority of the allowed communication device), and the priority of the allowed communication device is the priority of the MAC address of the allowed communication device. The priority of the storage space can be set and divided according to the priority of the allowed communication MAC address.
[0078] In the specific implementation, in order to improve the efficiency of packet receiving, a piece of memory is applied for as skb storage memory (SKB_BUFF) when the network driver is initialized. The size is n*skb_max_len (skb maximum length), and it is divided according to the priority. The diagram of data packet priority can be referred to Figure 5 , divide the priority into 3, then the memory will occupy the first n / 3 skb_max_len according to the priority 1, and then be divided down in sequence, and finally get multiple preset storage spaces, and determine the data processing priority of each storage space.
[0079] In a feasible implementation manner, step S30 may include steps A301 to A303:
[0080] Step A301, obtaining the preset priority number.
[0081] It is understandable that the preset priority number can be the number of priorities, for example, the priority can be divided into 4 levels; the data processing priority can also be converted into the priority of the data source address.
[0082] Step A302, obtaining the storage space size according to the preset priority number.
[0083] It is understandable that the number of storage spaces can be determined based on the preset priority number, but because the data priorities are different and because the data in the high-priority storage space is processed first, the data in the low-priority storage space is processed the slowest, and data retention may occur.
[0084] It should be understood that the total storage space can be divided according to its size and the number of preset priorities, and then the priority of each storage space can be determined. The size of each storage space can be adjusted based on the priority to determine the size of each priority storage space.
[0085] Step A303: divide the preset storage space according to the size of the storage space to obtain a plurality of preset storage spaces.
[0086] It is understandable that the priority and storage space size of each storage space are first determined to divide the total space for storing data packets to obtain a plurality of preset storage spaces.
[0087] In this implementation, by associating the priority of the data source address, the priority of the storage space and the priority of the data packet, and allocating the data packet storage value to the storage space of the corresponding priority according to the source address priority of the data packet, the importance of the received data can be divided, which facilitates the subsequent transmission of the data in the storage space according to the priority of the storage space, effectively improving the data transmission efficiency.
[0088] The above are merely feasible implementations before step S30 provided in this embodiment, and this embodiment does not specifically limit the specific implementations before step S30.
[0089] Step S40: transmitting the target data packet in the target storage space based on the data processing priority of the target storage space.
[0090] It is understandable that the kernel may send data packets in each preset storage space to the target address when performing output transmission.
[0091] It should be noted that the kernel will give priority to sending data packets in the storage space with the highest priority. While processing the data in the target storage space, it monitors whether there are data packets to be sent in the storage space with a higher priority than the target storage space. If so, the data packets in the high-priority storage space will be processed first.
[0092] In a feasible implementation, step S40 may include steps A41 to A42:
[0093] Step A41, identifying the state of data to be processed in a reference storage space, wherein the reference storage space is a preset storage space having a higher data processing priority than the target storage space.
[0094] It is understandable that if the data in the target storage space is to be processed, it is necessary to first determine whether there are any unprocessed data packets in the reference storage space having a higher priority than the target storage space.
[0095] It should be understood that the state of data to be processed may include no data to be processed and data to be processed.
[0096] Step A42, when the state of the data to be processed is that there is no data to be processed, the target data packet in the target storage space is transmitted.
[0097] It is understandable that when the state of the data to be processed is no data to be processed, it may be that the reference databases with a higher priority than the target database are all in a blank state, and there is no data packet that needs to be processed.
[0098] It should be noted that, when the state of the data to be processed is no data to be processed, the target address of the target data packet is obtained; when the target address belongs to a preset whitelist, the target data packet is transmitted.
[0099] Among them, it should be noted that when sending the target data packet in the target storage space, it is also necessary to perform security verification on the address of the device to which the target data packet is to be delivered (target address). The security verification method can be to match the target address of the target data packet with the device address allowed to communicate in the preset whitelist, and determine whether the target address belongs to the address in the whitelist. If it is in the whitelist, data transmission can be performed on the target data packet.
[0100] In the specific implementation, the process of sending the target data packet in the target storage space can refer to Figure 6 In the figure, the driver_xmit of the driver processing flow is used to determine whether the packet needs to be discarded, that is, the whitelist verifies the mac address. The specific method is to parse the network message from the data contained in the skb, and then parse the destination mac address from the EthernetHeader, and then compare it with the mac address list in the host_weight file. If the mac address of the data packet to be sent does not exist, it will be discarded; otherwise, it will be sent to the network device for processing according to the normal process.
[0101] In the present embodiment, data in each storage space is transmitted according to the priority of each data storage space. Before the data in each storage space is transmitted, the target address of each target data packet to be transmitted is further verified. When the target address belongs to the address whitelist of allowed communication equipment, data is sent. This can ensure data transmission efficiency based on the data storage space priority while improving the security of data transmission.
[0102] The above are only feasible implementations of step S40 provided in this embodiment, and this embodiment does not specifically limit the specific implementation of step S40.
[0103] The present embodiment provides a kernel data transmission method, which parses the target data packet received by the kernel to obtain the priority of the target data packet, stores the data packet in a storage space corresponding to the priority based on the priority of the data packet, and transmits the data packets in the storage space in sequence based on the priority of each storage space, so as to realize sequential processing of different data packets according to the priority of the data, improve the network transmission efficiency of the data based on the priority of the kernel processing the data, and transmit the data over the network more efficiently.
[0104] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 7 , step S30, the kernel data transmission method further includes steps S31-S32:
[0105] Step S31, matching the data priority with the priorities of a plurality of preset storage spaces to obtain a target storage space.
[0106] It is understandable that the data priority may be the priority of the source address in the data packet.
[0107] It should be understood that storage spaces with the same priority are divided based on the priority of each source address.
[0108] It should be noted that matching the data priority with the priorities of multiple preset storage spaces can be to see which preset storage space has the same priority as the data priority, and store the target data packet into the target storage space with the same priority.
[0109] In a feasible implementation manner, before step S31, steps A3101 to A33103 may be included:
[0110] Step A3101, obtain the source address of the target data packet.
[0111] It should be noted that before obtaining the source address of the target data packet, it also includes: obtaining the device network address and device priority of the allowed communication device; storing the one-to-one corresponding device network address and the device priority to a preset storage file; and using the preset storage file as a preset whitelist.
[0112] It can be understood that the source address of the target data packet can be understood as the device address that sends the target data packet to the kernel.
[0113] Step A3102, when the source address belongs to the preset registration list, execute the step of matching the data priority with the priorities of multiple preset storage spaces to obtain the target storage space.
[0114] It should be noted that before storing the target data packet into the storage space of the corresponding priority, it is also necessary to determine whether the source address of the target data belongs to the MAC address whitelist of allowed communication devices. If it belongs to the whitelist, the target data packet can be stored in the target storage space. If it does not belong to the whitelist, the target data packet will be discarded.
[0115] Step A3103, when the source address does not belong to the preset report list, discard the target data packet.
[0116] In the specific implementation, a whitelist is used to verify the MAC address. That is, in the driver_recv process, the data is first copied from the network device to the CPU memory, and then the MAC address of the source of the data packet is parsed and compared with the description file host_weight. If it exists, it is retained, otherwise it is discarded.
[0117] In this implementation, the security of the source address of the target data packet to be stored in the target storage space is verified through a preset white list, and the data is stored after the verification is passed, thereby better ensuring the security of data transmission.
[0118] The above are merely feasible implementations before step S31 provided in this embodiment, and this embodiment does not specifically limit the specific implementations before step S31.
[0119] Step S32, storing the target data packet into the target storage space.
[0120] In the specific implementation, the remaining data packets are further optimized, the priority level corresponding to the mac address in the description file host_weight is obtained, and then the data packet is stored in SKB_BUFF according to the priority level. For example, if the data packet corresponding to the current mac address has a priority of 1, it is directly placed in the skb memory with a priority of 1 for processing. This memory will be sent to the protocol stack for subsequent processing. The skb data in SKB_BUFF is processed in a loop, and the data is sent to the protocol stack for data packet transmission according to the principle of high priority first processing.
[0121] This embodiment provides a kernel data transmission method. When transmitting data on the kernel-driven network, it ensures that the network data can process devices in the whitelist based on the method of verifying the MAC address of the network device, further strengthens the necessity of network security, and ensures high efficiency during network transmission by giving priority to data transmitted from high-priority devices.
[0122] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the kernel data transmission method of the present application. More simple transformations based on this technical concept are all within the protection scope of the present application.
[0123] This application also provides a kernel data transmission device, please refer to Figure 8 , the kernel data transmission device comprises:
