[0013] The embodiments of the present application provide a data transmission method, a data transmission device, a device, a medium and a product.

[0014] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0015] The data transmission method provided in the embodiment of the present application can be applied to the scenario of data transmission in a point-to-multipoint network. In a specific application scenario, data transmission is performed between the user side and the edge computing node, and there are multiple data transmission links between the user side and the edge computing node.

[0016] The following is a detailed description of the data transmission method provided in the embodiment of the present application in combination with the above-mentioned specific application scenarios.

[0017] Figure 1 A flowchart of a data transmission method provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, an embodiment of the present application provides a data transmission method, which can be executed by a server, which can be an independent server, a server cluster composed of multiple servers, or a cloud server for cloud computing processing. The data transmission method can specifically include the following steps: S102: Based on a data transmission requirement between a data transmitting end and a data receiving end, determine a first data transmission bandwidth that matches the data transmission requirement.

[0018] In the embodiment of the present application, according to the amount of data transmitted between the data transmitting end and the data receiving end, a first data transmission bandwidth required for transmitting the amount of data between the data transmitting end and the data receiving end is determined.

[0019] In one implementation, the data sending end may be a user-side network signal source, and correspondingly, the data receiving end may be an edge computing node. In another implementation, the data sending end may be an edge computing node, and correspondingly, the data receiving end may be a user-side network signal source.

[0020] In yet another implementation, the data transmitter and the data receiver may be intermediate nodes in the data transmission process.

[0021] S104, in the case where there are multiple data transmission links between the data transmitting end and the data receiving end, receiving data transmission bandwidth allocation information sent by the data transmitting end; the data transmission bandwidth allocation information is obtained by the data transmitting end performing a second data transmission bandwidth allocation process on the data transmission link based on a quality evaluation index of the data transmission link for each data transmission link; The sum of the multiple second data transmission bandwidths determined by the data sending end is the first data transmission bandwidth.

[0022] In the embodiment of the present application, there are two or more data transmission links between the data sending end and the data receiving end, the data sending end is connected to multiple intermediate nodes, and the data sending end and the multiple intermediate nodes form a point-to-multipoint network.

[0023] In the case where there are multiple data transmission links between the data sending end and the data receiving end, the data sending end performs a second data transmission bandwidth allocation process on each data transmission link according to a quality evaluation index of the data transmission link, and the sum of the second data transmission bandwidths of the multiple data transmission links determined by the data sending end is the first data transmission bandwidth.

[0024] Figure 2 A schematic diagram of a data transmission process provided in an embodiment of the present application, in one implementation, as Figure 2 As shown, the data sending end is the edge computing node, on which a microwave device is deployed for sending or receiving data. The data receiving end is the user side, on which two microwave devices are deployed for sending or receiving data. The arrow represents the data transmission direction, and the dotted line represents the connection line. The edge computing node and the user side are connected through multiple communication repeaters, which are bridge repeaters composed of a pair of wireless bridge devices, used for data forwarding between the edge computing node and the user side. Figure 2In the example, the edge computing node is connected to communication repeater 1 and communication repeater 2 in a point-to-multipoint manner, communication repeater 1 is connected to communication repeater 3 in a point-to-point manner, and communication repeater 2 is connected to communication repeater 4 in a point-to-point manner. There are two data transmission links between the edge computing node and the user side, one is: edge computing node-communication repeater 1-communication repeater 3-user side; the other is: edge computing node-communication repeater 2-communication repeater 4-user side. In this case, the edge computing node first needs to determine the first data transmission bandwidth required for data transmission based on the amount of data transmitted; then, the edge computing node determines the data transmission bandwidth of the two data transmission links respectively according to the quality evaluation index of the two data transmission links, and after determination, allocates the corresponding second data transmission bandwidth to the two data transmission links. The sum of the second data transmission bandwidths of the two data transmission links is the first data transmission bandwidth.

[0025] Figure 3 Another data transmission process diagram provided in an embodiment of the present application, in another implementation, such as Figure 3 As shown, data is sent from the edge computing node and reaches the user side via communication repeater 1, communication repeater 2, communication repeater 3, communication repeater 4 and communication repeater. The edge computing node is connected to communication repeater 1 point-to-point, and communication repeater 1 is connected to communication repeater 2 and communication repeater 3 point-to-multipoint. Data is sent from the edge computing node and first passes through communication repeater 1. Data is sent from communication repeater 1 to the user side, and there are two data transmission links. One is: communication repeater 1-communication repeater 2-communication repeater 4-user side; the other is: communication repeater 1-communication repeater 3-communication repeater 5-user side. In this case, when there are two data transmission links between communication repeater 1 and the user side, communication repeater 1 can calculate the quality evaluation index of the two data transmission links respectively, and calculate the data transmission bandwidth allocated to the two data transmission links according to the quality evaluation index. The communication repeater 1 can send the data transmission bandwidth calculation result to the edge computing node, and the edge computing node will allocate the data transmission bandwidth to the two data transmission links.

[0026] In one embodiment, the quality assessment index of the data transmission link is obtained by the data sending end by acquiring at least one network parameter of the data transmission link, determining, for each network parameter, a first weight value of the network parameter based on the value of the network parameter, and determining the index based on the first weight value of each network parameter and the value of each network parameter.

[0027] In an embodiment of the present application, the data transmitting end determines the quality evaluation index of each data transmission link before performing the second data transmission bandwidth allocation processing on the data transmission link according to the quality evaluation index of the data transmission link. When determining the quality evaluation index of the data transmission link, the data transmitting end first obtains at least one network parameter of the data transmission link; then, for each network parameter, according to the value of the network parameter, determines the first weight value of the network parameter, so that the first weight value of each network parameter can be obtained respectively; then, according to the first weight value of each network parameter and the value of each network parameter, determines the quality evaluation index of the data transmission link.

[0028] The quality assessment index of the data transmission link is used to measure the communication quality of the data transmission link. By determining the quality assessment index, the communication quality of the data transmission link is determined, and the corresponding data transmission bandwidth is allocated to the data transmission link according to the communication quality of the data transmission link.

[0029] In one implementation, channel bandwidth (BW), client connection quality (CCQ), and signal-to-noise ratio (SNR) are key indicators for measuring the quality of wireless network communications. Channel bandwidth is used to evaluate the maximum data transmission capacity of the network to ensure that data transmission requirements are met; client connection quality is used to measure the stability of the wireless connection. The higher the client connection quality value, the fewer errors in the wireless connection; the signal-to-noise ratio is used to ensure that the signal strength is sufficient to overcome the noise. A high signal-to-noise ratio helps improve communication quality. When determining the quality evaluation index of the data communication link, the data transmitter can calculate the quality evaluation index of the data transmission link based on the channel bandwidth, client connection quality, and signal-to-noise ratio.

[0030] When calculating the quality evaluation index, considering the different ranges and distributions of the channel bandwidth, client connection quality, and signal-to-noise ratio, in order to enable the quality evaluation index to reflect the impact of the three parameters in a balanced manner, first, the channel bandwidth, client connection quality, and signal-to-noise ratio are normalized, that is, converted into a standard normal distribution. Specifically, the channel bandwidth, client connection quality, and signal-to-noise ratio can be normalized using formula (1): ; (1) In formula (1), is the value of the network parameter; the value of i is the channel bandwidth, client connection quality and signal-to-noise ratio; represents the mean of network parameters; Represents the standard deviation of the network parameters.

[0031] In specific implementation, the actual numerical distribution of channel bandwidth, client connection quality and signal-to-noise ratio over a period of time can be statistically analyzed, and the mean and standard deviation of channel bandwidth, client connection quality and signal-to-noise ratio can be unbiasedly estimated based on the statistical results.

[0032] After normalizing the channel bandwidth, client connection quality, and signal-to-noise ratio, the weight values ​​of the channel bandwidth, client connection quality, and signal-to-noise ratio need to be calculated respectively. When calculating the weight values ​​of the channel bandwidth, client connection quality, and signal-to-noise ratio, the weight values ​​of the above three network parameters can be calculated through the weight adaptive adjustment mechanism to more comprehensively and truly evaluate the comprehensive communication quality. The weight values ​​of the network parameters are calculated as follows: ; (2) In formula (2), Represents the weight value of the network parameter; represents network parameters, i is the value of channel bandwidth, client connection quality and signal-to-noise ratio, is the normalized network parameter value. The wireless quality evaluation index is calculated based on the weight values ​​of the channel bandwidth, client connection quality, and signal-to-noise ratio and the normalized values ​​of the channel bandwidth, client connection quality, and signal-to-noise ratio. The calculation method is as follows: = × ; (3) ; (4) In formula (3), represents the wireless quality assessment index; Represents the inhibitory factor used to make the quality assessment index Subject to minimum parameter values; is the network parameter value after normalization; represents the weight value of the network parameter, and the value of i is the channel bandwidth, client connection quality and signal-to-noise ratio; in formula (4), Indicates inhibitory factor, is the number of network parameters, in this case the value is 3; is the normalized network parameter value.

[0033] In one implementation, after determining the quality evaluation index of each data transmission link, each data transmission link may be weighted according to the quality evaluation index, and further, a corresponding data transmission bandwidth may be allocated to each data transmission link according to the weight value of each data transmission link.

[0034] In one embodiment, after receiving the data transmission bandwidth processing information sent by the data sending end, the method further includes: Monitor network parameters of data transmission links; In the case of monitoring a change in the value of at least one network parameter, determining whether the quality evaluation index of the data transmission link meets a preset update condition; the preset update condition includes: the change value of the network parameter exceeds a preset change threshold and the update interval of the quality evaluation index exceeds a preset update interval; When it is determined that the quality assessment index meets the preset update conditions, an index update instruction is sent to the data sending end, so that the data sending end updates the quality assessment index based on the value of the changed network parameter, and adjusts the second data transmission bandwidth of the data transmission link based on the updated quality assessment index.

[0035] In one implementation, after receiving the data transmission bandwidth processing information sent by the data transmitting end, the network parameters of each data transmission link are monitored, so as to recalculate and allocate the data transmission bandwidth of each data transmission link when the network parameters change. Specifically, Figure 4 A schematic diagram of a process for updating the data transmission bandwidth of a data transmission link provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, the updating process of the data transmission bandwidth of the data transmission link specifically includes the following steps: S401: Monitor whether at least one network parameter changes.

[0036] Among them, network parameters include three network parameters: channel bandwidth in the data transmission link, client connection quality and signal-to-noise ratio.

[0037] S402: Determine whether the quality evaluation index of the current data transmission link meets a preset update condition.

[0038] Specifically, the preset update condition includes that the change value of the network parameter exceeds the preset change threshold and the update interval of the quality evaluation index exceeds the preset update interval. In the case where the change value of the network parameter exceeds the preset change threshold and the update interval of the quality evaluation index exceeds the preset update interval, S404 is executed, followed by S405; otherwise, S403 is executed.

[0039] S403: Do not recalculate the quality evaluation index of the data transmission link.

[0040] S404: Recalculate the quality evaluation index of the data transmission link according to the changed value of the network parameter.

[0041] Specifically, the quality evaluation index of the data transmission link can be recalculated according to the value of the changed network parameter using the above formula (1) to formula (4).

[0042] S405: Calculate the data transmission bandwidth of each data transmission link according to the recalculated quality evaluation index.

[0043] S406: reallocate the data transmission bandwidth of each data transmission link according to the calculation result.

[0044] By calculating the quality evaluation index of each data transmission link and allocating corresponding data transmission bandwidth to each data transmission link according to the quality evaluation index, the data transmission bandwidth of each data transmission link is no longer fixed, but changes dynamically according to the quality evaluation index of the data transmission link and the data transmission demand. This can not only make full use of bandwidth resources, but also improve the stability and efficiency of data transmission.

[0045] S106: Perform data transmission between the data transmitting end and the data receiving end based on the data transmission bandwidth allocation information.

[0046] After allocating corresponding data transmission bandwidth to each data transmission link, data transmission is performed between the data transmitting end and the data receiving end.

[0047] In one embodiment, the data transmission link includes a plurality of bridge devices; the method further includes: Receiving channel frequency adjustment information sent by the network management device; The channel frequency adjustment information is obtained by the network management device by adjusting the channel frequencies of multiple bridge devices with overlapping channel frequencies based on the channel frequency monitoring information.

[0048] In the embodiment of the present application, channel frequency adjustment information sent by the network management device is also received, and the channel frequency adjustment information is obtained by the network management device adjusting the channel frequencies of multiple bridge devices with overlapping channel frequencies based on the channel frequency monitoring information. Multiple bridge devices can be deployed on a communication repeater in a data transmission link for data forwarding.

[0049] In one embodiment, the data transmission link includes a plurality of bridge repeaters for transmitting data sent by a data sending end; the network management device is used to store device status information of the plurality of bridge devices; The channel frequency monitoring information is obtained by the network management device determining whether multiple bridge devices belong to the same bridge repeater based on the device status information of each bridge device and the connection method between each bridge device. When it is determined that multiple bridge devices belong to the same bridge repeater, the channel frequency monitoring of multiple bridge devices is performed.

[0050] In an embodiment of the present application, the network management device is capable of storing device status information of multiple bridge devices. The network management device determines whether multiple bridge devices belong to the same bridge repeater based on the device status information of each bridge device and the connection method between each bridge device. When it is determined that multiple bridge devices belong to the same bridge repeater, the network management device monitors the channel frequencies of the multiple bridge devices to determine whether the channel frequencies of the multiple bridge devices overlap.

[0051] In one implementation, the network management device may be a network management server deployed in an edge computing node. The network management server can store and analyze the device status information of each device on the data transmission link and comprehensively monitor and manage the network. The network management server can periodically monitor the channels of a pair of bridge devices that form a bridge repeater, and automatically adjust the overlapping channel frequencies to stagger the use of channels, increase channel bandwidth, and optimize network performance. Specifically, Figure 5 A schematic diagram of a flow chart of adjusting the channel frequency of a bridge device by a network management server provided in an embodiment of the present application, such as Figure 5 As shown, the process of adjusting the channel frequency of the bridge device by the network management server specifically includes the following steps: S501: Determine whether two bridge devices belong to the same bridge repeater.

[0052] Specifically, the network management server can determine whether the two bridge devices belong to the same bridge repeater by collecting device status information. When it is determined that the two wireless bridge devices are connected via a network cable and do not belong to the same WiFi (wireless network), execute S503 and then execute S504; otherwise, execute S502.

[0053] S502: Determine that the two bridge devices belong to different bridge repeaters.

[0054] S503: Determine that the two bridge devices belong to the same bridge repeater.

[0055] S504: Determine whether there is channel frequency overlap between two bridge devices.

[0056] Specifically, the network management server can determine whether the two bridge devices have overlapping channel frequencies by retrieving the channel frequency information in the device status information of the two bridge devices constituting a bridge repeater. If there is overlapping channel frequencies, execute S506, then execute S507; otherwise, execute S505.

[0057] S505: Do not adjust the channel frequencies of the two bridge devices.

[0058] S506: The network management server triggers the two bridges constituting the bridge repeater to perform a wireless environment detection and collects the detection results.

[0059] S507: According to the detection result, new channel frequencies are selected for the two bridges constituting the bridge repeater, and the channel frequencies of the bridge devices are reconfigured.

[0060] In the embodiment of the present application, first, based on the data transmission demand between the data transmitting end and the data receiving end, a first data transmission bandwidth matching the data transmission demand is determined; then, in the case where there are multiple data transmission links between the data transmitting end and the data receiving end, the data transmission bandwidth allocation information sent by the data transmitting end is received; the data transmission bandwidth allocation information is obtained by the data transmitting end performing a second data transmission bandwidth allocation process on the data transmission link based on the quality evaluation index of the data transmission link for each data transmission link; the sum of the multiple second data transmission bandwidths determined by the data transmitting end is the first data transmission bandwidth; then, based on the data transmission bandwidth processing information, data transmission between the data transmitting end and the data receiving end is performed. It can be seen that through the embodiment of the present application, in the case where there are multiple data transmission links between the data transmitting end and the data receiving end, the data transmitting end can determine the data transmission bandwidth of each data transmission link according to the quality evaluation index of each data transmission link, and allocate a matching second data transmission bandwidth to each data transmission link according to the first data transmission bandwidth matching the data transmission demand, and the data transmission bandwidth of each data transmission link is no longer fixed, but dynamically changes according to the quality evaluation index of the data transmission link and the data transmission demand, so that not only can the bandwidth resources be fully utilized, but also the stability and efficiency of data transmission can be improved.

[0061] The embodiment of the present application also provides a method for constructing data transmission equipment. In one implementation method, the following steps are specifically included: Step 1: Erect a pole on the roof or other high point on the user side, fix multiple wireless microwave devices, connect to the user's local area network through a wired connection, establish a user-side network signal source, and establish a wireless connection with a nearby communication repeater. Step 2: Build a communication repeater group between the user side and the edge computing node. The distance between all communication nodes in the same communication repeater group is less than or equal to two kilometers, and complete the communication between the signal source and the receiver through as few communication repeaters as possible. Step 3: Fix multiple wireless microwave devices on the communication tower where the edge computing node is located to establish a receiver. Step 4: The receiver is connected to the edge computing node through a wired connection, and the network management server and computing server are deployed in the edge computing node.

[0062] In one possible implementation, all communication devices will independently and regularly transmit the device status information of the current communication device to the network management server. The network management server will receive logs and alarm data sent by all communication devices in the local area network. If the device is disconnected and the connection is not restored within the set time, the alarm data will be sent to the network administrator via SMS or application (APP). The network management server can detect the channel frequency occupied by a pair of bridge repeaters that make up the communication repeater. If the channel frequency range overlaps, the network management server can automatically modify it to increase the channel bandwidth and optimize the wireless transmission performance.

[0063] In another implementation, when there is no obstruction between the user side and the edge computing node, that is, there is no obstruction, or there is an obstruction but the height of the obstruction is not higher than the height of the highest point of the communication tower where the communication repeater is located, when the distance between the user side and the edge computing node is far, point-to-point data transmission can be performed between the user side and the edge computing node through the communication repeater. If the distance between the user side and the edge computing node is within two kilometers, then in this case, data forwarding between the user side and the edge computing node can be performed without a communication repeater, and the user side and the edge computing node can directly form a wireless transmission channel point-to-point. Obstructions are, for example, office buildings, trees, or other communication tower equipment. Figure 6 A schematic diagram of a method for constructing a data transmission device provided in an embodiment of the present application, such as Figure 6 As shown, in one example, there is no obstruction between the edge computing node and the user side, and the distance between the user side and the edge computing node is far, and the two perform point-to-point data transmission through two communication repeaters.

[0064] In another implementation, when there is an obstruction between the user side and the edge computing node, and the height of the obstruction is higher than the height of the highest point of the communication tower where the communication repeater is located, in this case, it is necessary to use a communication repeater close to the user side to forward data, so as to bypass the obstruction and transmit data with the edge computing node. Figure 7 A schematic diagram of another method of constructing a data transmission device provided in an embodiment of the present application is shown in FIG. Figure 7 As shown, in one example, there is an office building between the edge computing node and the user side, and the height of the office building is higher than the highest point of the communication tower where each communication repeater is located. By setting a communication repeater on the communication tower in front of or behind the office building, and connecting the communication repeater close to the edge computing node and the communication repeater close to the user side respectively, the office building can be bypassed to realize data transmission between the user side and the edge computing node.

[0065] Corresponding to the data transmission method provided in the above embodiment, based on the same technical concept, the embodiment of the present application also provides a data transmission device, Figure 8A schematic diagram of the module composition of a data transmission device provided in an embodiment of the present application is shown in FIG. Figure 8 As shown, the data transmission device includes: A determination module 801 is used to determine a first data transmission bandwidth matching the data transmission requirement based on the data transmission requirement between the data transmitting end and the data receiving end; The receiving module 802 is used to receive the data transmission bandwidth allocation information sent by the data transmitting end when there are multiple data transmission links between the data transmitting end and the data receiving end; the data transmission bandwidth allocation information is obtained by the data transmitting end performing a second data transmission bandwidth allocation process on the data transmission link based on the quality evaluation index of the data transmission link for each of the data transmission links; The sum of the plurality of second data transmission bandwidths determined by the data transmitting end is the first data transmission bandwidth; The transmission module 803 is used to perform data transmission between the data sending end and the data receiving end based on the data transmission bandwidth processing information.

[0066] In a possible implementation, the quality assessment index of the data transmission link is obtained by the data sending end by acquiring at least one network parameter of the data transmission link, determining, for each of the network parameters, a first weight value of the network parameter based on the value of the network parameter, and determining the index based on the first weight value of each network parameter and the value of each network parameter.

[0067] In a possible implementation, the second data transmission bandwidth of the data transmission link is determined by the data sending end based on the quality assessment index of the data transmission link and the second weight value of the data transmission link.

[0068] In a possible implementation, the receiving module 802 is further configured to monitor the network parameters of the data transmission link; In the case of monitoring a change in the value of at least one of the network parameters, determining whether the quality evaluation index of the data transmission link meets a preset update condition; the preset update condition includes: the change value of the network parameter exceeds a preset change threshold and the update interval of the quality evaluation index exceeds a preset update interval; When it is determined that the quality assessment index meets the preset update conditions, an index update instruction is sent to the data sending end, so that the data sending end updates the quality assessment index based on the changed value of the network parameter, and adjusts the second data transmission bandwidth of the data transmission link based on the updated quality assessment index.
