[0021] 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.

[0022] 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.

[0023] The main solution of the embodiment of the present application is: obtain the device data stream sent by the service terminal device; identify the service type of the device data stream to obtain the service type identification result of the device data stream; determine the transmission port priority corresponding to the device data stream according to the service type identification result; set the data transmission parameters of the transmission port corresponding to the device data stream according to the transmission port priority, and forward the device data stream through the corresponding transmission port.

[0024] As various devices in modern factories and industrial facilities, including programmable logic controllers (PLCs), radars, cameras, sensors, etc., are gradually connected to the Internet, forming a highly interconnected industrial ecosystem, these devices not only need to collect and exchange large amounts of data in real time, but also place higher requirements on the real-time, reliability and security of data transmission.

[0025] In the prior art, data forwarding and scheduling generally involves a unified, one-time manual priority configuration of physical ports. The ports forward data according to the configured priority, which may result in high-priority data services being connected to low-priority ports, causing the service data to be forwarded in a low-priority state. In other words, the existing port priority configuration method is a static priority allocation strategy that lacks flexibility and intelligence and cannot adapt to dynamically changing industrial environments and business needs.

[0026] The present application provides a solution, which obtains the device data stream sent by the service terminal device, and then identifies the service type of the device data stream to obtain the service type identification result, and then sets the transmission priority for the transmission port corresponding to the device data stream according to the priority corresponding to each type of service, and then further configures the corresponding data encapsulation format according to the transmission port priority, and finally forwards the encapsulated device data stream through the corresponding transmission port. This solution determines the data transmission priority according to the service type identification result of the data packet, ensuring that high-priority services can be forwarded preferentially at high-priority ports, ensuring the data transmission quality of key services.

[0027] Based on this, an embodiment of the present invention provides a terminal side data transmission scheduling method, referring to Figure 1 , Figure 1 The present invention is a flowchart of a first embodiment of a terminal-side data transmission scheduling method.

[0028] In this embodiment, the terminal side data transmission scheduling method includes the following steps: Step S10: Acquire the device data stream sent by the service terminal device.

[0029] It should be noted that the execution subject of this embodiment can 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 that can realize the above functions, a cloud server, etc. The following takes the cloud server as an example to illustrate this embodiment and the following embodiments.

[0030] It should be noted that the terminal-side data transmission scheduling method recorded in this application is applied to gateway devices directly connected to various types of industrial equipment terminals, such as the common 5G TAN deterministic gateway. The 5G TAN deterministic gateway is a gateway device designed specifically for industrial Internet and time-sensitive applications. It has the characteristics of high speed, large connection, wide coverage, low latency and high reliability. It can be widely used in distribution network differential protection, cloud PLC, remote control and mobile precision timing and other scenarios that require 5G to provide deterministic network connection.

[0031] It is understandable that in a typical industrial remote control scenario, terminal devices such as PLC machines, cameras, radars, locators, and sensors may randomly access the LAN port of any 5G deterministic gateway in the area according to the real-time task content for data transmission. These devices are equivalent to business terminal devices, and the data forwarded through the gateway is the device data stream. It should be noted that at this time, these devices may not have been configured with data transmission priorities. On the one hand, these devices may be connected to the local area network for the first time, and neither the local gateway nor the next-level gateway that is about to forward data has configured corresponding priorities for them. On the other hand, the gateway device accessed by the terminal device in each data transmission task may be different, so a dynamic and intelligent method is needed to manage and optimize the transmission priority of the data stream.

[0032] It should be understood that the core idea of ​​the technical solution of this application needs to be explained here first, such as Figure 2 As shown, Figure 2 The figure is a schematic diagram of the entire service process of the present invention. Since data transmission of different service types has different real-time requirements, for example, PLC control data has higher real-time requirements, while monitoring video and environmental sensor sampling data have lower real-time requirements, the former should be assigned a high priority during data transmission, and the latter needs to be configured as a low priority. Therefore, the present application sets a priority mapping table corresponding to the real-time requirements of the service type of the data stream in the gateway directly connected to the terminal device, so that the terminal-side gateway can automatically identify the data stream uploaded by the connected device, and then identify the service type in the data stream to differentiate the priority allocation for each connected device, and then further allocate the data stream to ports with different forwarding rates, thereby realizing differentiated data transmission of field service data.

[0033] Step S20: performing service type identification on the device data flow to obtain a service type identification result of the device data flow.

[0034] It should be noted that enhanced DPI identification technology is required to identify the service type of device data streams. DPI is the abbreviation of Deep Packet Inspection technology, which is a network packet filtering technology used to check the data portion of the data packet passing through the detection point (which may include its header) to detect protocols that do not match the specifications, viruses, spam, intrusions, or to determine whether the detected data packet can pass or needs to be routed to other different destinations according to preset access criteria. It can also be used to collect statistical data. Traditional DPI identification technology is deployed in the forwarding equipment of operators and Internet service providers for firewall-related malicious identification, and mainly plays a role in information transmission security. Therefore, DPI technology has not yet been clearly applied in the field of priority planning of terminal-side gateways.

[0035] It can be understood that the introduction of DPI technology in the terminal-side gateway can enable the gateway to have the ability to actively identify real-time transmitted data, and the device data stream enters the gateway in the Ethernet data frame format, where the application layer message in the data frame format contains the MAC address, application layer protocol, application port number, and feature fingerprint information of the data message. The terminal-side gateway uses DPI technology to identify the characteristics of the data stream regarding the business type.

[0036] It should be understood that DPI identification technology can be identified based on feature words. Different applications usually use different protocols, and various protocols have their own special fingerprints. These fingerprints may be specific ports, specific strings or specific bit sequences. It can be identified based on the application layer gateway. For services with separated control flow and business flow, the business flow has no characteristics. The application layer gateway identification technology first identifies the control flow and selects a specific application layer gateway to parse the business flow according to the control flow protocol. It can also be identified based on behavior patterns, and the business can be distinguished through statistical data such as the frequency of business changes. It can be seen that in the specific implementation process, the business type can be identified based on the different characteristics of the business data, and the business type identification results of the data flow from multiple angles can be obtained. Since the identification process is a process similar to judgment, it is not completely accurate. Therefore, through the multi-angle identification code, and then combined with the weights of each identification result, the type with the largest confidence value is taken as the result of this business identification.

[0037] Step S30: Determine the transmission port priority corresponding to the device data flow according to the service type identification result.

[0038] It should be noted that before this step, the service type of the device data stream has been identified by enhanced DPI technology, and the service type identification results have been obtained. These results are usually specific types of service flows, such as video streams, file transfers, real-time control signals, etc. In this step, a predefined mapping relationship table from service type to transmission port priority is required. This table clearly defines the priority level corresponding to each service type.

[0039] In one embodiment, determining the transmission port priority corresponding to the device data stream based on the service type identification result includes: obtaining a mapping relationship table between service type identification results and service priorities; determining the transmission priority of the device data stream based on the mapping relationship table; and determining the transmission port priority corresponding to the device data stream based on the transmission priority of the device data stream.

[0040] It can be understood that the mapping relationship table between the service type identification result and the service priority is a data structure that associates different service types in the network with their corresponding priorities. This mapping relationship table enables the network device to dynamically assign different priority processing to different service flows based on the service type identification result. Figure 3 As shown, Figure 3 This is an example diagram of the service priority mapping relationship table. It can be seen from the figure that the order of priority is arranged from high to low. PLC control, as the highest level of priority, can achieve the highest port access priority. This category of data should be transmitted through the port with the highest forwarding rate. Subsequent categories are assigned ports with different forwarding rates according to the priority order. In the specific implementation, the determined physical port priority information is written into the priority field of the TAN protocol. This field is used in the TAN frame to identify the priority of the data packet so that it can be correctly processed during the data forwarding process. It should be emphasized that writing the priority field of the TAN protocol in the physical port priority information makes the identification in the entire TAN network universal. Any gateway in the TAN network can determine the priority of the data transmitted from the port based on this part of the field information.

[0041] Step S40: according to the transmission port priority, set the data transmission parameters of the transmission port corresponding to the device data flow, and forward the device data flow through the corresponding transmission port.

[0042] It should be noted that, based on the priority of the transmission port, the gateway device can decide which data encapsulation format to use. For example, high-priority data may need to use the fast PDU (protocol data unit) format, while low-priority data may use the standard PDU format, so that high-priority data packets may be sent to ports with higher bandwidth and lower latency.

[0043] In one embodiment, the data transmission parameters of the transmission port corresponding to the device data stream are set according to the transmission port priority, including: obtaining TAN protocol priority field information according to the transmission port priority and TAN protocol priority mapping table; and setting the data encapsulation format of the transmission port based on the TAN protocol priority field information.

[0044] It should be noted that after determining the priority of the transmission port, the priority of the transmission port needs to be bound to the priority field of the TAN protocol. That is, when the priority of the transmission port is high, the high priority field in the TAN protocol is also written into the priority identification field of the transmission port. The beneficial effect of this is that the data from the southbound access device of the terminal-side gateway can be forwarded with differentiated priority on the terminal side at the same time, and the service data on the server side is transmitted to the service platform again with differentiated priority, thereby ensuring that key services can obtain the necessary service quality assurance throughout the transmission path and meet the requirements of low latency, high reliability, etc.

[0045] It is understandable that before forwarding data, the terminal device corresponding to the current data stream needs to register the transmission priority. Due to the special application scenarios of terminal gateway devices, the devices that access the gateway for data transmission are random. Therefore, every time a new terminal device is connected, it is necessary to automatically register the terminal, assign it a transmission priority, and broadcast it to other transmission gateways.

[0046] In one embodiment, before forwarding the encapsulated device data stream through the corresponding transmission port, it also includes: generating transmission priority registration information based on the transmission priority and source MAC address of the device data stream; uploading the transmission priority registration information to the remote controller, and completing the transmission priority registration of the device data stream at the remote controller.

[0047] It should be understood that the gateway device on the terminal side identifies the service type of the passing data stream through the enhanced DPI technology, and determines the transmission priority of the data stream according to the service type. The gateway device then registers the port priority information to the remote controller. This step involves binding the port priority with the priority field of the TAN protocol. In this way, the remote controller can understand the priority setting of each port and schedule and manage the data stream accordingly, thus realizing the two-stage mapping of service priority-port priority-protocol priority, automatically establishing the mapping of service traffic and TAN protocol, realizing the terminal-side frame priority forwarding and frame preemption, and ensuring the service quality of industrial field service data stream transmission.

[0048] This embodiment obtains the device data stream sent by the service terminal device, and then identifies the service type of the device data stream to obtain the service type identification result, and then sets the transmission priority for the transmission port corresponding to the device data stream according to the priority corresponding to each type of service, and then further configures the corresponding data encapsulation format according to the priority of the transmission port, and finally forwards the encapsulated device data stream through the corresponding transmission port. This solution determines the data transmission priority according to the service type identification result of the data packet, ensuring that high-priority services can be forwarded at high-priority ports first, ensuring the data transmission quality of key services.

[0049] 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 4 , the step S20 comprises: Step S201: extracting data from the device data stream to obtain an application layer message.

[0050] It should be noted that the device data stream is encapsulated into UDP packets for transmission by the TAN protocol, and the TAN protocol encapsulates the Ethernet data frames entering the gateway into PDUs (Protocol Data Units). PDU is a data unit transmitted in network communications. It contains information from the upper layer and information attached to the current layer entity, that is, the device data stream enters the gateway in the format of Ethernet data frames. The basic format of an Ethernet frame includes preamble, frame start delimiter, destination MAC address, source MAC address, type / length field, data field, and frame check sequence.

[0051] It is understandable that if Figure 5 As shown, Figure 5 The figure is a schematic diagram of the TAN protocol encapsulation structure. The UDP header in the figure is the header of the UDP message, which contains information such as the source port number, the destination port number, the UDP message length and the checksum; the TAN header is the header of the TAN protocol, which is located after the UDP header. The TAN header contains the control information required by the TAN protocol and is used to process the encapsulation and transmission details specific to the TAN protocol; the standard Ethernet header is the header of the Ethernet frame, which contains the destination MAC address, the source MAC address and the type / length field. The type / length field indicates the type or length of the data payload (PAYLOAD) in the frame; PAYLOAD is the data part of the UDP message, which contains the application layer data. In the context of the TAN protocol, PAYLOAD is the data encapsulated by the TAN protocol, which will be transmitted to the destination; CRC (Cyclic Redundancy Check) is a cyclic redundancy check code used to detect whether an error occurs in the frame during transmission, so the CRC code is located at the end of the entire frame.

[0052] It should be understood that the application layer message is the PAYLOAD part. PAYLOAD is the data part of the UDP message, which contains the application layer data. In the TAN protocol, PAYLOAD is the data encapsulated by the TAN protocol, which will be transmitted to the destination. Therefore, this part of the data contains the MAC address, application layer protocol, application port number, and feature fingerprint information of the data message, and the traffic type identification has the characteristics of refinement.

[0053] Step S202: Identify the application layer message through a deep message inspection algorithm to obtain a service feature identification result.

[0054] It should be noted that, in this embodiment, the service type is identified based on three features: feature word identification, application layer gateway, and behavior pattern identification.

[0055] It can be understood that signature identification refers to the use of characteristic character strings of specific protocols or applications to identify specific application types in data streams. For example, some protocols have fixed byte sequences at specific locations in data packets. These sequences can be used as "fingerprints" to identify protocols, and the business type identification results of data streams can be obtained based on this. Application layer gateway identification is suitable for services where control streams and business streams are separated. This type of data stream needs to first identify the control stream, and then parse it through a specific application layer gateway according to the protocol of the control stream, identify the corresponding business stream from the protocol content, and then determine the business type of the data stream based on the business stream. Behavior pattern identification is based on the analysis of the behavior that has been implemented by the terminal to determine the user's ongoing or upcoming actions. It is usually used to identify services that cannot be determined based on protocols.

[0056] In one embodiment, the application layer message is identified by a deep message detection algorithm to obtain a service feature identification result, including: performing feature word identification on the application layer message to obtain a feature word service type identification result; performing application layer gateway identification on the application layer message to obtain an application layer gateway service type identification result; performing behavior pattern identification on the application layer message to obtain a behavior model service type identification result; and using the feature word service type identification result, the application layer gateway service type identification result and the behavior model service type identification result as the service feature identification result.

[0057] Step S203: Obtaining a service type identification result of the device data flow according to the service feature identification result and its corresponding feature identification weight.

[0058] It can be understood that the service message first undergoes application layer data extraction, evaluates the matching degree of DPI multi-recognition methods, generates feature word recognition, application layer gateway, behavior pattern serial recognition weighted values ​​I, J, K, and parallel recognition generates feature word recognition service type confidence vector , the confidence vector of the application layer gateway identifying the service type , Behavior pattern recognition business type confidence vector , and determine the business type identification result according to the following formula.

[0059]

[0060] It should be understood that the confidence vector contains multiple sub-elements, each of which represents the confidence of an identification result. Specifically, each sub-element corresponds to a possible service type or traffic category. For example, when the service type includes video streaming, audio streaming, file transfer, etc., each sub-element in the confidence vector represents the model's confidence that the input data belongs to these categories. Generally speaking, the value of each sub-element represents the model's confidence in the corresponding category. The larger the value, the more confident the model is that the input data belongs to the category. In the identification process, identification is performed from three perspectives: feature word recognition, application layer gateway, and behavior pattern. Combined with the weight of each identification method, the confidence of multiple traffic categories of the remote control scenario service can be calculated through the calculation of the above formula, and then the type with the largest confidence value is taken as the result of this service identification, and then a one-stage mapping of service priority to port priority is performed to obtain a 5G TAN gateway port priority mapping solution.

[0061] This embodiment uses a deep message detection algorithm to perform fine-grained identification of application layer messages and distinguish different business types. This identification does not rely solely on a single feature, but combines three methods: feature word identification, application layer gateway identification, and behavior pattern identification, which improves the accuracy and reliability of identification. Since the solution combines a variety of identification methods for different data features, it can adapt to different network environments and business types, has strong adaptability and flexibility, and enables the terminal-side gateway to perform differentiated data transmission through automated identification and priority mapping, thereby improving the overall data transmission efficiency and quality.

[0062] This application also provides a terminal side data transmission scheduling device, please refer to Figure 6 , the terminal side data transmission scheduling device includes: The data transmission module 10 is used to obtain the device data stream sent by the service terminal device; A service type identification module 20, configured to identify the service type of the device data flow and obtain a service type identification result of the device data flow; A data analysis module 30, configured to determine the transmission port priority corresponding to the device data flow according to the service type identification result; The data transmission module 10 is further used to set the data transmission parameters of the transmission port corresponding to the device data flow according to the transmission port priority, and forward the device data flow through the corresponding transmission port.

[0063] In one embodiment, the business type identification module 20 is also used to extract data from the device data flow to obtain application layer messages; identify the application layer messages through a deep message detection algorithm to obtain business feature identification results; and obtain business type identification results of the device data flow based on the business feature identification results and their corresponding feature identification weights.

[0064] In one embodiment, the service type identification module 20 is further used to perform feature word identification on the application layer message to obtain a feature word service type identification result; perform application layer gateway identification on the application layer message to obtain an application layer gateway service type identification result; perform behavior pattern identification on the application layer message to obtain a behavior model service type identification result; and use the feature word service type identification result, the application layer gateway service type identification result and the behavior model service type identification result as the service feature identification result.

[0065] In one embodiment, the data analysis module 30 is also used to obtain a mapping relationship table between business type identification results and business priorities; based on the mapping relationship table, determine the transmission priority of the device data stream; and according to the transmission priority of the device data stream, determine the transmission port priority corresponding to the device data stream.

[0066] In one embodiment, the data transmission module 10 is further used to obtain TAN protocol priority field information according to the transmission port priority and TAN protocol priority mapping table; and to set the data encapsulation format of the transmission port based on the TAN protocol priority field information.

[0067] In one embodiment, the data transmission module 10 is also used to generate transmission priority registration information based on the transmission priority and source MAC address of the device data stream; upload the transmission priority registration information to the remote controller, and complete the transmission priority registration of the device data stream at the remote controller.

[0068] This embodiment obtains the device data stream sent by the service terminal device, and then identifies the service type of the device data stream to obtain the service type identification result, and then sets the transmission priority for the transmission port corresponding to the device data stream according to the priority corresponding to each type of service, and then further configures the corresponding data encapsulation format according to the priority of the transmission port, and finally forwards the encapsulated device data stream through the corresponding transmission port. This solution determines the data transmission priority according to the service type identification result of the data packet, ensuring that high-priority services can be forwarded at high-priority ports first, ensuring the data transmission quality of key services.
