See Figure 1. FIG. 1 is a functional block diagram of a data transmission path selection system 1 according to an embodiment of the present invention. As shown in Figure 1, in this specific embodiment, the data transmission path selection system 1 includes a terminal device 11 and a control and management device 12, and the control and management device 12 communicates with the terminal device 11 through a plurality of transmission paths P. The control and management device 12 includes an analysis module 121, a path selection module 122 and a detection module 123, and the path selection module 122 is connected to the analysis module 121 and the detection module 123.

In practice, the terminal device 11 and the control management device 12 can be computers or servers, and a transmission path P can be established between the terminal device 11 and the control management device 12 in a wired or wireless connection to communicate and transmit data. Taking the financial industry as an example, the control and management device 12 can be a data center server of a financial institution, and the terminal device 11 can be a computer of a bank clerk in the financial institution. In a specific embodiment, the control and management device 12 can be a data center server of the financial institution's head office, and the terminal device 11 can be a data center server of a branch of the financial institution, or even a data center server of an overseas branch of the financial institution. .

In this specific embodiment, the terminal device 11 contains device information. The analysis module 121 of the control management device 12 is used to obtain the device data of the terminal device 11 , and the analysis module 121 analyzes the device data through an algorithm to generate a transmission type corresponding to the terminal device 11 . In practice, the device data may be the IP location of the terminal device 11, but is not limited to this. The transmission type may be a transmission protocol type of the Internet, and may be a transmission protocol that maximizes data transmission efficiency achieved by the terminal device 11 Definite type. The transmission protocol types of the Internet can be File Transfer Protocol (FTP), HyperText Transfer Protocol (HTTP), Domain Name System (DNS) in the application layer of the communication protocol. ), Simple Network Management protocol (SNMP), etc., but are not limited to these.

In practice, a financial institution includes multiple different departments, and each department has different business projects. That is to say, the types of data transmitted by each terminal device 11 are different, such as: voice data, important system data, and video data. , information security system information, etc. The analysis module 121 can perform supervised learning, unsupervised learning, semi-supervised learning, reinforcement learning, linear search algorithm, sequential search algorithm, and binary search algorithm. search algorithm), interpolation search algorithm (interpolation search algorithm), hashing search algorithm (hashing search algorithm), web crawler and other methods respectively analyze various data types to establish rule models. Moreover, the analysis module 121 can also perform deep learning on data types to generate rule models, such as: multilayer perceptron, deep neural network (Deep Neural Network, DNN), convolutional neural network (Convolutional Neural Network). Network (CNN), Recurrent Neural Network (RNN). Therefore, after the analysis module 121 obtains the device data of the terminal device 11, the analysis module 121 can analyze the device data through machine learning and find the transmission type that is most suitable for the terminal device 11 to transmit data. In addition, since the financial institution includes a plurality of terminal devices 11, the analysis module 121 can further classify and plan the plurality of terminal devices 11 to the most suitable transmission type for transmitting data through a Boolean algebra algorithm.

As shown in Figure 1, in this specific embodiment, the transmission path P includes a first transmission path P1, a second transmission path P2 and a third transmission path P3, and the first transmission path P1, the second transmission path P3 The transmission path P2 and the third transmission path P3 respectively include the first transmission characteristic, the second transmission characteristic and the third transmission characteristic. In practice, the first transmission path P1, the second transmission path P2 and the third transmission path P3 are different network line types, and the first transmission characteristic, the second transmission characteristic and the third transmission characteristic may include transmission speed, Stability, bandwidth, signal quality, etc. It is worth noting that the first transmission characteristic of the first transmission path P1, the second transmission characteristic of the second transmission path P2, and the third transmission characteristic of the third transmission path P3 are not exactly the same. For example, the transmission delay of the first transmission path P1 is smaller than the transmission speed of the second transmission path P2, and the transmission delay of the second transmission path P2 is smaller than the transmission speed of the third transmission path P3; the signal quality of the second transmission path P2 is greater than The signal quality of the first transmission path P1 is greater than the signal quality of the third transmission path P3; the bandwidth of the third transmission path P3 is greater than the bandwidth of the second transmission path P2, and the second transmission path The bandwidth of the path P2 is greater than the bandwidth of the first transmission path P1. The transmission characteristics between the first transmission path P1, the second transmission path P2 and the third transmission path P3 are not limited to the above arrangement, and can be determined according to the design or requirements. In addition, the number of transmission paths is not limited to 3, and the number of transmission paths may also be 2 or 4 or more.

In this specific embodiment, the path selection module 122 selects one of the first transmission path P1, the second transmission path P2, and the third transmission path P3 as the main transmission path according to the transmission type of the terminal device 11 to communicate with the terminal device 11. 11Carry out data transmission. In practice, the path selection module 122 may be a controller, but is not limited thereto. Furthermore, the path selection module 122 and the analysis module 121 can also be integrated into the analysis control chip. After the analysis module 121 analyzes the device data of the terminal device 11 and generates a transmission type corresponding to the terminal device 11, the path selection module 122 can select the data transmission efficiency that can maximize the data transmission efficiency achieved by the terminal device 11 according to the transmission characteristics of the transmission type. transmission path as the main transmission path. For example, when the transmission type of the terminal device 11 is HTTP , the path selection module 122 uses the first transmission path P1 with the smallest transmission delay as the main transmission path. At this time, data transmission is performed between the terminal device 11 and the control management device 12 through the first transmission path P1. When the transmission type of the terminal device 11 is FTP, the path selection module 122 uses the third transmission path P3 with the largest transmission bandwidth as the main transmission path, and the connection between the terminal device 11 and the control management device 12 is through the third transmission path. Path P3 carries out data transmission.

In this specific embodiment, the first transmission path P1, the second transmission path P2 and the third transmission path P3 respectively include a first signal interference value, a second signal interference value and a third signal interference value. In practice, the first signal interference value, the second signal interference value and the third signal interference value may include signal loss value (loss value), signal delay value (latency value), signal jitter value (jitter value), etc., and the third signal interference value The first signal interference value, the second signal interference value and the third signal interference value are floating values (ie, variable values). Since the transmission path P may cause signal interference due to internal network lines or external factors when transmitting data, thereby affecting the transmission characteristics of the transmission path P, therefore, when the first transmission path is used between the terminal device 11 and the control management device 12 When P1 performs data transmission and the first signal interference value of the first transmission path P1 is too large, the transmission efficiency between the terminal device 11 and the control management device 12 will be reduced.

In this specific embodiment, the detection module 123 pre-stores the signal interference threshold and is used to detect the first signal interference value and the second signal interference value of the first transmission path P1, the second transmission path P2 and the third transmission path P3. and the third signal interference value. In practice, the signal interference threshold may include a signal loss threshold, a signal delay threshold and a signal jitter threshold. When the signal interference value of the transmission path detected by the detection module 123 exceeds the signal interference threshold, the path selection module 122 switches from the primary transmission path to the secondary transmission path before transmitting data. For example, data transmission is performed between the terminal device 11 and the control management device 12 through the first transmission path P1 as the main transmission path. Lose. When the detection module 123 detects that the first signal interference value of the first transmission path P1 exceeds the signal interference threshold, it means that the first transmission path P1 has been unable to achieve the function of maximizing data transmission efficiency. At this time, the detection module 123 can generate a warning signal, and the path selection module 122 can switch the transmission path from the first transmission path P1 to the second transmission path P2 or the third transmission path P3 (ie, the secondary transmission path) according to the warning signal. transmission path) for data transmission between the terminal device 11 and the control management device 12. In practice, the signal loss threshold can be between 2% and 15%, and the signal delay threshold can be between 90ms and 300ms. However, in practice, it is not limited to this. The signal interference threshold can also be set according to the design or needs. .

Furthermore, the detection module 123 can generate a warning signal according to the degree of signal interference. In practice, the detection module 123 may generate a warning signal only when one or at least two of the signal loss value, signal delay value and signal jitter value exceed the signal interference threshold. Moreover, the first transmission path P1, the second transmission path P2 and the third transmission path P3 can respectively set different signal interference thresholds according to the transmission characteristics, and the first transmission path P1, the second transmission path P2 and the third transmission path P3 The signal interference threshold can be determined by default or by analysis of large amounts of historical transmission data. In addition, the basis for the path selection module 122 to switch the transmission path from the first transmission path P1 to the second transmission path P2 or the third transmission path P3 may be preset or determined based on the order of transmission characteristics from largest to smallest.

In practice, when the path selection module 122 switches the transmission path from the first transmission path P1 to the second transmission path P2, the detection module 123 simultaneously detects the first signal interference value and the second signal interference value of the first transmission path P1. The second signal interference value of the transmission path P2. In a specific embodiment, when the first signal interference value is less than the signal interference threshold, it means that the first transmission path P1 has restored transmission quality and can achieve the function of maximizing data transmission efficiency. At this time, the path selection module 122 will The transmission path is switched from the second transmission path P2 back to the first transmission path P1 for data transmission between the terminal device 11 and the control management device 12 . In a specific example, when the first signal interference value and the second signal interference value respectively exceed the signal interference threshold, it means that neither the first transmission path P1 nor the second transmission path P2 can achieve the function of maximizing data transmission efficiency. At this time, the path selection module 122 switches the transmission path from the second transmission path P2 to the third transmission path P3 for data transmission between the terminal device 11 and the control management device 12 . Further, when the path selection module 122 switches the transmission path to the third transmission path P3, the detection module 123 simultaneously detects the first signal interference value of the first transmission path P1 and the second signal of the second transmission path P2. The interference value and the third signal interference value of the third transmission path P3. When the first signal interference value, the second signal interference value and the third signal interference value are all greater than the signal interference threshold, it means that all transmission paths cannot transmit data normally. At this time, the path selection module 122 can switch the transmission path again. Return to the first transmission path P1 or the control management device 12 to generate a fault message.

Therefore, the data transmission path selection system of the present invention can select the transmission path that can maximize data transmission efficiency as the main transmission path according to the transmission types of different terminal devices, so as to improve transmission efficiency and reduce costs. Moreover, the data transmission path selection system of the present invention can also detect the interference level of the transmission path in real time, and switch to other secondary transmission paths according to the interference level of the transmission path to maintain a certain degree of transmission quality and thereby improve transmission efficiency.
