[0053] In order to make the purposes, technical solutions and advantages of the present application clearer, further detailed description will be made to the present application in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0054] The data transmission method provided by the embodiments of the present application can be applied in an application environment as shown in Figure 1 The terminal 102 is connected with the edge computing device 106 through the relay device 104, the terminal 102 transmits the to-be-transmitted data to the relay device 104 through a network, and the relay device 104 transmits the received data to the edge computing device 106 through a network. The data storage system can store the data required to be processed by the edge computing device 106. The data storage system can be integrated on the edge computing device 106, or can be placed on a cloud or other network server. The terminal 102 can be a wired connection terminal, or can be a wireless connection terminal, including but not limited to various personal computers, notebook computers, smart phones, tablet computers, Internet of Things devices and portable wearable devices, the Internet of Things devices can be smart speakers, smart televisions, smart air conditioners, smart vehicle devices, etc. The portable wearable device can be a smart watch, a smart bracelet, a head-mounted device, etc. The edge computing device 106 can be deployed in an edge computing platform, and can be realized by an independent edge computing device or an edge computing device cluster composed of multiple edge computing devices.

[0055] In one embodiment, as shown in Figure 2 A data transmission method is provided, which is applied to an edge computing device in Figure 1 for example, and includes the following steps:

[0056] S201, receiving a connection request sent by a relay device, wherein the connection request is sent by a terminal to the relay device.

[0057] The relay device is a device used for receiving data sent by a sending terminal and sending the received data to a receiving terminal in network data transmission. Optionally, the relay device can be a switch, which can be a TSN switch. The TSN switch based on Time Sensitive Networking (TSN) has deterministic latency and multi-protocol transmission capability, low delay, low jitter, and high reliability, which can guarantee deterministic transmission of data and network multiplexing. The relay device can also be composed of a communication network integrated TSN switch, or the relay device can also be composed of a base station integrated TSN switch.

[0058] It should be noted that in the process of data transmission, the terminal can send the data to be transmitted to the relay device, and the relay device sends the received data to the receiving device. When the data volume is large or the data latency requirement is high, the relay device can send the received data to the edge computing device, and the edge computing device can manage the data to be transmitted to improve the processing efficiency of the data to be transmitted. The terminal device can include a wired connection terminal and a wireless connection terminal. In this embodiment, the transmission relationship between different terminals and the edge computing device can be referred to as shown in Figure 3 , wherein the wired connection terminal can transmit data to the edge computing device through the TSN switch, and the wireless connection terminal can transmit data to the edge computing device through the communication network combined with the TSN switch.

[0059] In this embodiment, the relay device can receive the connection request sent by the terminal, and then send the received connection request to the edge computing device. The connection request sent by the terminal can include device information of the terminal and parameter information of the data to be transmitted, such as data packet size, latency requirement, data transmission period, etc.

[0060] In the embodiment, the edge computing device can include a data transceiver module, a time-sensitive network control module, an edge cloud computing module, and a data storage module. The data transceiver module is configured to receive connection requests and data of all terminals and send control information of the edge computing device. The time-sensitive network control module is configured to control transmission management of the data. The edge cloud computing module is configured to perform computing processing on the received data and generate control information according to the processing result. The data storage module is configured to store data received and output by other modules.

[0061] In S202, the first configuration information corresponding to the terminal is determined according to the connection request by using the pre-established time-sensitive network. The first configuration information includes a transmission strategy of the first data to be transmitted from the terminal to the edge computing device.

[0062] It should be noted that the time-sensitive network (TSN) defines a time-sensitive mechanism for Ethernet data transmission. By combining priority with time division multiplexing, the available transmission time is allocated to data packets according to priority, so as to provide zero congestion loss and limited delay for various time-sensitive data streams coexisting on the network. The TSN has the advantages of limited delay, reliable data packet forwarding, coexistence with Ethernet, and the like. The TSN adds determinism of data transmission to the standard Ethernet. In addition, the TSN can send a data copy during transmission and delete the duplicate data at the destination to ensure the reliability of the transmitted data, thereby ensuring the stability of Ethernet transmission. Therefore, in the embodiment, the time-sensitive network control module can be set in the edge computing device according to the pre-established time-sensitive network, to manage and control the transmission time of the data to be transmitted by the terminal, so as to ensure the deterministic transmission of the data.

[0063] Optionally, in the embodiment, the edge computing device can further include a data transceiver module configured to receive connection requests and data of all terminals and send control information of the edge computing device, an edge cloud computing module configured to perform computing processing on the received data and generate control information according to the processing result, and a data storage module configured to store data received and output by other modules.

[0064] The first configuration information refers to a transmission strategy of the data to be transmitted by the terminal in the edge computing device. The first data refers to the data to be transmitted from the terminal to the edge computing device. The first configuration information can include parameter information of the edge computing device and a transmission strategy of the transit device for forwarding the first data to the edge computing device.

[0065] In this embodiment, the edge computing device can determine the first configuration information corresponding to the terminal according to the received connection request by using the pre-established time-sensitive network. Optionally, the transmission path, transmission cycle and other information of the terminal can be determined according to the device information of the terminal in the connection request by using the time-sensitive network. The transmission delay requirement, transmission bandwidth size, transmission cycle and other information according to the first data can be determined according to the parameter information of the first data in the connection request by using the time-sensitive network.

[0066] S203, the first configuration information is sent to the relay device, wherein the first configuration information is used to instruct the relay device to transmit the first data to the edge computing device according to the transmission strategy.

[0067] In this embodiment, the edge computing device can send the first configuration information to the relay device after determining the first configuration information. The relay device can perform sending control on the first data according to the transmission strategy in the received first configuration information after receiving the first data sent by the terminal, and transmit the received first data to the edge computing device according to the transmission strategy.

[0068] Optionally, in this embodiment, for the wired connection terminal, the edge computing device can send the first configuration information to the TSN switch. For the wireless connection terminal, the edge computing device can send the first configuration information to the relay device composed of the communication network fusion TSN switch.

[0069] As an optional implementation, after the edge computing device transmits the first configuration information to the relay device, the edge computing device can also send a configuration success message to the relay device, and the relay device forwards the configuration success message to the terminal. After receiving the configuration success message, the terminal starts to send the first data to be transmitted.

[0070] It can be understood that if the first data to be transmitted in the terminal changes, the terminal needs to resend a new connection request. The edge computing device generates new first configuration information according to the received new connection request, and sends the new first configuration information to the relay device. The relay device performs transmission control on the current first data according to the received new first configuration information.

[0071] In the data transmission method, in a case where the terminal sends a connection request to the relay device, the edge computing device receives the connection request sent by the relay device, determines first configuration information including a transmission strategy of first data transmitted by the terminal to the edge computing device according to the connection request by using a pre-established time-sensitive network, sends the first configuration information to the relay device, so that the relay device can control the first data according to the transmission strategy in the received first configuration information, and then transmits the first data to the edge computing device. Compared with the prior art, since the edge computing device can control the transmission time of the first data to be transmitted by the terminal by using the pre-established time-sensitive network, and sends the generated first configuration information to the relay device, so that the relay device can control the transmission of the first data according to the first configuration information, the precise scheduling and management of the first data are realized, so that the edge computing device can process the received data in the case where the transmission time of the first data is determined, avoiding the problem that the low processing efficiency of the edge computing device caused by the uncertain transmission time of the first data and the low latency processing requirement cannot be realized. In turn, the low latency characteristic of the edge computing device can be realized. In addition, since the first configuration information is determined according to the connection request received by the edge computing device, the determined first configuration information can accurately control the first data of different terminals, further improving the processing efficiency of the edge computing device for the received data, and realizing the low latency characteristic of the edge computing device.

[0072] In the above scenario of determining the first configuration information corresponding to the terminal according to the connection request, the first configuration information can be determined by analyzing the connection request and the result obtained by analyzing. In one embodiment, as shown in Figure 4 S202 includes:

[0073] S301, the connection request is analyzed and processed to obtain a terminal address and transmission parameters, wherein the transmission parameters include a latency requirement, a data packet size, and a data transmission period.

[0074] The terminal address refers to the device IP, MAC address and other information of the terminal sending the connection request, and the transmission parameters refer to the related information of the first data to be transmitted. The latency requirement in the transmission parameters refers to the time requirement of data transmission from one end of the network to the other end. The latency can include sending latency, propagation latency, processing latency and queuing latency, and the total latency is the sum of the above sending latency, propagation latency, processing latency and queuing latency. Different data has different requirements for latency. For example, the latency requirement of financial data transmission is high. The data packet size in the transmission parameters refers to the length of the data frame of the first data to be transmitted. The larger the data, the longer the data frame. Different link layers can bear different lengths of data frames.

[0075] In the embodiment, the edge computing device can send the received connection request to the time-sensitive network control module, and parse the connection request according to a transmission protocol between the edge computing device and the relay device to obtain a terminal address and a transmission parameter of the first data.

[0076] S302, determining first configuration information according to the terminal address and the transmission parameter by using the time-sensitive network.

[0077] In the embodiment, the device IP and the MAC address of the terminal can be determined according to the terminal address, and then the terminal is allocated a port address of the relay device receiving the connection request and the first data according to the determined device IP and MAC address. The priority parameter can be determined according to the time delay requirement of each data in the first data in the time delay requirement in the transmission parameter. The allocation of the transmission line of each data in the first data can be determined according to the data packet size in the transmission parameter. The sending time of each data in the first data can be determined according to the data transmission period in the transmission parameter.

[0078] It should be noted that, in the embodiment, the first configuration information is determined according to the terminal address and the transmission parameter by using the time-sensitive network through a time-aware shaper (TAS) mechanism defined in the IEEE802.1Qbv standard of the time-sensitive network. Different priority flows are assigned to 0-7 traffic class (TC) queues. The time-aware shaper mechanism dynamically provides on / off control for different priority queues at the exit based on a set periodic gating list, so as to guarantee the bandwidth and delay time of each transmission queue and realize deterministic transmission of flows.

[0079] The time-aware shaper can be used to protect the data transmission queue with strict time requirement from the interference of other network information. When the priority is very high, a preemption mechanism can be used. For particularly important data, a preemption mechanism IEEE802.1Qbu is specified in the time-aware shaper. The preemption mechanism can configure preemption parameters, that is, if a low-priority data frame is being sent, the system receives another high-priority data frame, interrupts the low-priority data frame being sent, and sends the high-priority data frame, and then re-sends the low-priority data.

[0080] In this embodiment, the edge computing device determines the terminal address and the transmission parameter by analyzing the connection request, determines the first configuration information according to the terminal address and the transmission parameter by using the time-sensitive network, and makes the first configuration information determined based on the terminal address and the transmission parameter of the first data to be transmitted, thereby ensuring the accuracy of the determined first configuration information, avoiding the problem that the transmission time of the first data is inaccurate due to inaccurate first configuration information, and ensuring that the transit device can accurately control the transmission of the first data according to the determined first configuration information.

[0081] In the above scenario of determining the first configuration information according to the terminal address and the transmission parameter, different first configuration information can be determined according to different terminals. In one embodiment, the terminal includes a wired connection terminal, such as Figure 5 As shown in the above S302, it includes:

[0082] S401, determining a first network connection path according to the terminal address.

[0083] The network connection path refers to the address information of the devices of the nodes in the transmission network through which the data is transmitted. In this embodiment, the first network connection path can be the address information of the devices of the nodes in the transmission network when the wired connection terminal sends the first data to the edge computing device. Optionally, the first network connection path can be the IP address of the node device, or the MAC address of the node device. In this embodiment, the address of the wired connection terminal can be used to determine which port of the TSN switch receives the data sent by the wired connection terminal, and which port of the TSN switch transmits the data to the edge computing device.

[0084] S402, determining one of the first gating list parameter and the first preemption parameter, and the first priority parameter according to the transmission parameter.

[0085] The priority parameter refers to a transmission queue of each data in the first data to be transmitted. In this embodiment, the first priority parameter refers to a priority parameter of the wired connection terminal for sending the first data to the edge computing device. The preemption parameter refers to that if a low-priority data frame is being sent, the system receives another high-priority data frame, interrupts the low-priority data frame being currently sent, and sends the high-priority data frame, and then re-sends the low-priority data. In this embodiment, the first preemption parameter refers to a preemption parameter of the wired connection terminal for sending the first data to the edge computing device. The gate list parameter defines a state of a transmission gate for transmitting data in an output port of the TSN switch. The state of the transmission gate includes two states of “on” and “off”. Different priority data streams can be mapped to different transmission queues. Only when the state of the transmission gate is “on”, the data stream can be transmitted by the TSN switch. In this embodiment, the gate list parameter can be determined according to the data packet size, data transmission period, priority parameter and the like. The TSN switch can schedule the transmission of the data stream in each queue according to the gate list parameter, so as to guarantee the bandwidth and latency of the queue with high priority, and realize the deterministic transmission of the data to be transmitted. In this embodiment, the first gate list parameter refers to a gate list parameter of the wired connection terminal for sending the first data to the edge computing device.

[0086] In this embodiment, the first priority parameter of the first data to be transmitted can be set according to the time-sensitive network IEEE802.1Qbv standard defined by the time-aware shaper mechanism according to the delay transmission requirement, and then the first gate list parameter can be calculated according to the set first priority parameter and the data packet size. For example, for a data packet with a size of 512B, a data transmission period of 100ms, and a delay requirement of 100ms, the gate period in the gate list parameter of the data to be transmitted is 100ms. In a gate period, two gate list parameters can be divided. The divided gate list parameters can be as shown in Table 1. When the total time period of the two gate lists is 100ms and the link bandwidth is 1Gbps, the time period of the first gate list can be calculated according to the time period = data packet length / link bandwidth, which is 4096ns, and the gate value is 00001000, indicating that only the state of queue 3 in the TSN switch is “on”, i.e., the data with a priority of 3 is allowed to pass. The time period of the second gate list is 999,995,904ns, and the gate value is 11111111, indicating that the state of all gate queues in the TSN switch is “on”, and all data is allowed to pass.

[0087] In the embodiment, the edge computing device can determine the first priority parameter of the first data to be transmitted by the wired connection terminal according to the parsed latency requirement, and can determine the first gating list parameter or the first preemption parameter of the first data to be transmitted according to the determined first priority parameter and the quantity of the first data to be transmitted, and optionally, if the quantity of the first data to be transmitted is less than a preset threshold, the first preemption parameter of the first data to be transmitted is determined, and in the embodiment, the first preemption parameter of the first data to be transmitted can be determined according to the first priority parameter; if the quantity of the first data to be transmitted is greater than or equal to the preset threshold, the first gating list parameter of the first data to be transmitted is determined, and in the embodiment, the first gating list parameter of the first data to be transmitted can be determined according to the first priority parameter, and the packet size and the data transmission period in the transmission parameter, and for example, the first priority parameter and the first preemption parameter determined according to the connection request sent by the wired connection terminal can be as shown in Table 2, wherein the first data can be divided into 8 priority parameters according to the latency requirement of the first data.

[0093] In the embodiment, the time-sensitive network control module in the edge computing device can use the time-sensitive network to determine the path information of the wired connection terminal for transmitting data according to the first network connection path, determine the time sequence of transmitting the first data according to the first priority parameter, and determine the gating information of the transit device for forwarding data according to one of the first gating list parameter and the first preemption parameter, so as to determine the first configuration information according to the determined path information of the wired connection terminal for transmitting data, the time sequence of data transmission, and the gating information of the transit device for forwarding data.

[0094] In the embodiment, the first network connection path is determined according to the terminal address, one of the first gating list parameter and the first preemption parameter is determined according to the transmission parameter, and the first priority parameter is determined, so that the first configuration information can be determined according to the one of the first gating list parameter and the first preemption parameter, the first network connection path, and the first priority parameter by using the time-sensitive network. Since the first configuration information is determined by the terminal address and the transmission parameter through the wired connection, the accuracy of the first configuration information is ensured, the accuracy of the transmission control of the first data to be transmitted by the transit device according to the first configuration information is ensured, and the processing efficiency of the edge computing device for the received data is improved.

[0097] It should be noted that in the embodiment, the communication network can be combined with the TSN switch. The wireless connection terminal can be connected to the core network of the communication network through the communication network. The core network of the communication network is network-connected with the TSN switch. The mapping relationship between the service type of the communication network system and the traffic classification in the TSN is established. The data transmitted by the wireless connection terminal is transmitted to the edge computing platform through the TSN switch. The communication network can be a 5th Generation Mobile Communication Technology (5G) network.

[0098] The network connection path refers to the path of the device address or the network receiving port address of each node in the transmission network through which the data is transmitted. In the embodiment, the first network connection path can be the network connection path through which the wireless connection terminal transmits the first data to the edge computing device. Optionally, the first network connection path can include the IP address and the network receiving port address of each node device in the transmission network, or can include the MAC address and the network receiving port address of each node device.

[0099] In the embodiment, the address of the wireless connection terminal can be acquired to determine through which port of the 5G network the data transmitted by the wireless connection terminal is received, through which port of the 5G network the data is transmitted to the TSN switch, through which port of the TSN switch the data is received, and through which port of the TSN switch the data is transmitted to the edge computing device.
