With the rapid development of mobile Internet, the demand for various smart devices to connect to the 4G network through hotspots for data transmission is increasing, and the data types transmitted are rich and diverse, including audio, video, files, etc.

[0003] The patent application with publication number CN108064441 B discloses a method for optimizing accelerated network transmission, including the following steps: an accelerated access node receives a data message and obtains the source station address and port of the data message; the accelerated access node determines the type of the data message; when the data message is a TCP message, the intermediate node of the accelerated network optimizes the transmission of the TCP message to the accelerated exit node, and the accelerated exit node communicates with the source station based on the TCP transmission protocol according to the source station address and port; when the data message is a UDP message, the accelerated access node encapsulates the UDP message into an authenticatable TCP message, the intermediate node of the accelerated network optimizes the transmission of the authenticatable TCP message to the accelerated exit node, the accelerated exit node parses the authenticatable TCP message into the UDP message, and the accelerated exit node then communicates with the source station based on the UDP transmission protocol according to the source station address and port.

[0004] However, when some existing network transmission optimization systems are in use, the 4G network bandwidth is easily affected by factors such as the environment and the number of users, which causes fluctuations, resulting in freezes, delays, and even packet loss during data transmission, seriously affecting the user experience. Traditional methods cannot reasonably match the transmission performance of the link and the characteristics of the data, so that data cannot be transmitted on the optimal link, reducing the overall transmission efficiency. Summary of the invention

[0010] An optimization information output unit is used to perform transmission processing on the data to be transmitted according to the generated transmission optimization information.

[0011] As a further solution of the present invention, the specific manner in which the network protocol analysis unit analyzes the transmission network information is:

Then, a group of classified transmission data is selected as the target object for analysis, and the corresponding transmission data in the target object is obtained, and recorded as a, where a = 1, 2, ..., b, where b represents the number of transmission data. The maximum delay and minimum bandwidth corresponding to the transmission data a are obtained and recorded as Ca and Ka respectively, and the obtained parameters are substituted into the formula Calculate the priority value corresponding to the transmission data a a , where ω is the weight coefficient corresponding to the maximum delay Ca, and (1-ω) is the weight coefficient corresponding to the minimum bandwidth.

Then calculate the average difference of the network bandwidth corresponding to the transmission network within the time period t, and compare the average difference of the network bandwidth with the threshold. If the average difference of the network bandwidth is greater than the threshold, it indicates that the current transmission network fluctuates, and an unstable transmission network result is generated. On the contrary, if the average difference of the network bandwidth is less than the threshold, it indicates that the current transmission network does not fluctuate, and a stable transmission network result is generated. Meanwhile, the stable transmission network result and the unstable transmission network result are analyzed separately.

[0022] As a further solution of the present invention, the transmission optimization analysis unit analyzes the unstable transmission network result in the following specific manner:

[0023] By analyzing the network bandwidth of the transmission network within the time T, and calculating the bandwidth mean corresponding to the network bandwidth, and taking the bandwidth mean as the standard to compare with the minimum transmission speed of the corresponding transmission link, if the bandwidth mean is greater than the minimum transmission speed, the data capacity of the data to be transmitted is segmented according to the minimum transmission speed to obtain segmented data packets, and the segmented data packets are transmitted to generate transmission optimization information;

[0024] If the bandwidth mean is less than the minimum transmission speed, the data capacity of the data to be transmitted is divided based on the bandwidth mean to obtain divided data packets, and then the divided data packets are evenly transmitted according to the number to generate transmission optimization information.

BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Figure 1 This is a block diagram of the system principle of the present invention;

[0033] Figure 2 It is a diagram of the steps of the present invention. DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] For example, see Figure 1 The present application provides a network transmission optimization system for hotspot products based on 4G network, including: a network information acquisition unit, a network protocol analysis unit, a transmission optimization analysis unit and an optimization information output unit, and combines Figure 1 It can be known that the above functional units are electrically connected in a unidirectional manner.

[0036] The network information acquisition unit is used to acquire the transmission network information corresponding to the hot product and transmit the acquired transmission network information to the network protocol analysis unit.

[0037] The network protocol analysis unit is used to analyze the acquired transmission network information. It analyzes the network protocol and transmits data in a fully connected manner between leaf nodes and spine nodes. It also calculates the priority of the data to be transmitted. It then selects different links based on the priority to generate transmission protocol information. The transmission protocol information is then transmitted to the transmission optimization analysis unit.

[0038] Get the server corresponding to the transmission network, and get the number of leaf nodes and spine nodes corresponding to the server at the same time, and connect the leaf node and the spine node in a fully connected manner to obtain a leaf-spine link, denoted as i, and i = 1, 2, ..., j, where j represents the number of leaf-spine links. The specific full connection means that each leaf node (access layer device, connecting to the server and other terminal devices) is directly connected to all spine nodes (core layer devices) by a physical link, and each spine node is also directly connected to all leaf nodes. Assume that a data center has 4 leaf nodes (labeled as L1, L2, L3, L4) and 3 spine nodes (labeled as S1, S2, S3), the fully connected mode means that leaf node L1 has links with spine nodes S1, S2, S3, and leaf node L2 also has links with S1, S2, S3, and so on. Each leaf node has links with all spine nodes. At the same time, spine node S1 also has links with leaf nodes L1, L2, L3, L4, and S2 and S3 also have links with all leaf nodes respectively. Then, the transmission information corresponding to the leaf-spine link i is obtained, and the transmission information includes the maximum transmission speed, minimum transmission speed and corresponding real-time transmission delay of the leaf-spine link. At the same time, the transmission value Link corresponding to the leaf-spine link i is calculated based on the transmission information. i , and the specific calculation method is: Get the maximum transmission speed Vi max and minimum transmission speed Vi min , and the corresponding real-time transmission delay CH i, then substitute the obtained parameters into the formula Calculate the transmission value Link corresponding to the leaf-spine link i i , where α is the weight coefficient corresponding to the maximum transmission speed, (1-α) is the weight coefficient corresponding to the minimum transmission speed, and the specific values ​​of the two are set by the operator;

[0039] At the same time, the data to be transmitted corresponding to the transmission network is obtained, and the classified transmission data is obtained according to the data type of the data to be transmitted, and is recorded as n, and n=1, 2, ..., m, where m represents the number of data types of the classified transmission data. Then, a group of classified transmission data is selected as the target object for analysis, and the corresponding transmission data in the target object is obtained, and is recorded as a, and a=1, 2, ..., b, where b represents the number of transmission data. Specifically, the transmission data here is the sub-data in the classified transmission data. For example, the target object here is audio data, and the corresponding transmission data a is the sub-audio data in the large category of audio data. The maximum delay and minimum bandwidth corresponding to the transmission data a are obtained and recorded as Ca and Ka respectively, and the obtained parameters are substituted into the formula Calculate the priority value corresponding to the transmission data a a , where ω is the weight coefficient corresponding to the maximum delay Ca, (1-ω) is the weight coefficient corresponding to the minimum bandwidth, and the specific value is set by the operator;

[0040] Similarly, the priority values ​​corresponding to all transmission data a are calculated, and the calculated priority values ​​are summed and averaged to obtain the priority of the target object. Similarly, the above calculation method is used to calculate the priority corresponding to the classified transmission data. a Calculate and then transmit data according to the classification priority a Sort them from large to small, and similarly sort the leaf-spine links i according to the transmission value Link i Sort from large to small, and match the classified transmission data with the leaf-spine link for transmission, generate transmission protocol information, and then transmit it to the transmission optimization analysis unit. The matching method here is to prioritize a Maximum Classification Transmission Data and Transmission Value Link i The largest leaf-spine link is matched, and then the links are matched in order from largest to smallest.

[0041] A transmission optimization analysis unit is used to analyze the acquired transmission protocol information, analyze the data to be transmitted, and judge the current transmission network to generate a stable transmission network result and an unstable transmission network result. At the same time, based on the corresponding transmission networks of the two, a transmission analysis is performed on the data to be transmitted to generate transmission optimization information, and then the transmission optimization information is transmitted to the optimization information output unit.

[0042] Acquire transmission protocol information, acquire data to be transmitted, and acquire the data type corresponding to the data to be transmitted. Then, acquire the corresponding transmission protocol according to the acquired data type. For example, the data type corresponding to the data to be transmitted is audio data and video data. According to the transmission protocol, acquire the corresponding transmission link for transmission for different types of data. At the same time, acquire the current transmission network, and acquire the unit network bandwidth corresponding to the current transmission network with time t as a period. The network bandwidth here is expressed as the corresponding transmission speed, and the specific unit is kb / s. The specific value of time t is set by the operator. If time t=5 seconds is used as a period, then calculate the average difference of the network bandwidth corresponding to the transmission network within the time period t. The specific calculation method is to calculate the network bandwidth difference corresponding to all adjacent unit network bandwidths, sum up all network bandwidth differences, and then calculate the overall mean, which is recorded as the average difference of the network bandwidth. Assuming that within a certain 20 seconds, every 5 seconds is a period, the network bandwidth data acquired are 1000kb / s, 1050kb / s, 980kb / s, and 1020kb / s respectively. Calculate the average difference of the network bandwidth corresponding to the transmission network within the time period t. The specific calculation method is: calculate the difference of the network bandwidth of all adjacent units, that is, (1050-1000)+(980-1050)+(1020-980), and get 50-70+40=20, then sum these differences and calculate the overall mean, 20÷3≈6.67kb / s, and record this value as the average network bandwidth difference. At the same time, compare the average network bandwidth difference with the threshold, and the specific value of the threshold is set by the operator. If the average network bandwidth difference is greater than the threshold, it means that the current transmission network fluctuates and generates an unstable transmission network result. On the contrary, if the average network bandwidth difference is less than the threshold , it means that there is no fluctuation in the current transmission network, and a stable transmission network result is generated; for example, set the threshold to 10kb / s, and compare the calculated average difference in network bandwidth with the threshold. If the average difference in network bandwidth is greater than the threshold, like in the above example, if the threshold is 5kb / s, because 6.67kb / s>5kb / s, it means that there is fluctuation in the current transmission network, and the system will generate an unstable transmission network result. On the contrary, if the average difference in network bandwidth is less than the threshold, for example, the average difference is 3kb / s, which is less than the set threshold of 5kb / s, it means that there is no fluctuation in the current transmission network, and the system will generate a stable transmission network result.

[0043] The generated stable transmission network result is analyzed to obtain the data to be transmitted and the corresponding transmission protocol, then obtain the transmission link corresponding to the transmission protocol, and obtain the minimum transmission speed corresponding to the transmission link, and compare the minimum transmission speed with the network bandwidth corresponding to the current stable transmission network, and the network bandwidth here is represented by the average value of the corresponding network bandwidth within time t. If the minimum transmission speed is greater than the network bandwidth, the data to be transmitted is divided according to the network bandwidth to obtain segmented data packets, and the transmission loads corresponding to the remaining transmission links are obtained, and the transmission loads are compared with the corresponding load thresholds, and the load thresholds are the thresholds corresponding to the respective transmission connections, and the specific values ​​are set by the operator. At the same time, the transmission links corresponding to the transmission loads less than the load thresholds are selected and recorded as the transmission links to be analyzed, and then the obtained segmented data packets are evenly divided according to the number and transmitted through the transmission links to be analyzed, and the transmission optimization information is generated. Specifically, the number of segmented data packets is evenly divided into two parts, and one of them is transmitted through the transmission links to be analyzed, and specifically, the segmented data packets after the equalization number are evenly divided twice according to the number of transmission links to be analyzed, and it is assumed that the obtained segmented data packets can be evenly divided;

[0044] If the minimum transmission speed is less than the network bandwidth, the data to be transmitted is segmented according to the minimum transmission speed to obtain segmented data packets, and the segmented data packets are transmitted at the set transmission rate to generate transmission optimization information, and the specific value of the transmission rate is set by the operator.

[0045] An optimization information output unit is used to perform transmission processing on the data to be transmitted according to the generated transmission optimization information.

[0046] Embodiment 2: This embodiment is implemented on the basis of Embodiment 1, and the difference from Embodiment 1 is as follows:

[0047] The transmission optimization analysis unit analyzes the generated unstable transmission network results by analyzing the network bandwidth of the transmission network within the time T, and calculating the bandwidth mean corresponding to the network bandwidth, and comparing the bandwidth mean with the minimum transmission speed of the corresponding transmission link. If the bandwidth mean is greater than the minimum transmission speed, the data capacity of the data to be transmitted is divided according to the minimum transmission speed to obtain divided data packets, and the divided data packets are transmitted to generate transmission optimization information;

[0048] If the broadband mean is less than the minimum transmission speed, the data capacity of the data to be transmitted is divided according to the broadband mean to obtain divided data packets, and then the divided data packets are evenly transmitted according to the number to generate transmission optimization information. The specific method of generating transmission optimization information here is similar to the transmission method of the divided data packets for the stable transmission network result.

[0049] Embodiment 3, as the embodiment 3 of the present invention, focuses on combining the implementation processes of embodiment 1 and embodiment 2 for implementation.

[0051] Step 1: Obtain the transmission network information corresponding to the hot product, use the full connection method of leaf nodes and spine nodes to transmit data, and calculate the priority of the transmission data;

[0052] Step 2: Select different links according to the priority to generate transmission protocol information, and judge the current transmission network to generate stable transmission network results and unstable transmission network results;

[0053] Step 3: For the stable transmission network results, segment the data to be transmitted by combining the transmission protocol information, and perform transmission optimization analysis based on the network bandwidth of the transmission network to generate transmission optimization information;

[0054] Step 4: For unstable transmission network results, the data to be transmitted is segmented in combination with the transmission protocol information. At the same time, transmission optimization analysis is performed based on the relationship between the network bandwidth of the transmission network and the transmission speed of the corresponding transmission link to generate transmission optimization information.
