With the development of network technology, terminals perform financial transactions, such as money transfer or online shopping, through a network. When an application server in a banking system processes a large amount of financial transaction flow generated by financial transactions based on own hardware resources, the situations of slow transaction, response overtime and even downtime caused by insufficient own hardware resources can occur, so that the application server cannot timely feed back response messages to a terminal (for example, after a terminal initiates transfer, the transfer success reminding fed back to the terminal by the application server is generated), the transaction is failed, and the customer experience is influenced.
Generally, by predicting a peak in the transaction, hardware resources to deploy the application server are increased in advance. This increases hardware resource costs and labor costs for operation and maintenance. When the application server processes less financial transaction traffic, hardware resources are wasted.

The embodiment of the present application does not limit the specific technology and the specific device form adopted by the terminal. In this embodiment, the terminal may access the internet 130 in a wired or wireless manner, perform financial transactions such as online shopping and money transfer through the internet 130, generate financial transaction traffic, and send the financial transaction traffic to the banking system 11 through the internet 130.
The internet 130, also known as the internet or the transliteration internet, the internet, is a huge network formed by connecting networks in series, and these networks are connected by a set of common protocols to form a logically single huge international network. In the embodiment of the present application, the internet 130 is used to forward the financial transaction traffic sent by the terminal to the banking system 11.
The control device 110 is connected to the M transmission devices and the N application servers by a wired or wireless connection. The control device 110 may be a separate physical device, such as a server or a computer. In this embodiment, the control device 110 may also be referred to as a traffic controller, and the control device 110 is configured to obtain a resource usage value of an application server included in the banking system 11, and adjust a rate at which the transmission device transmits the financial transaction traffic to the application server according to the resource usage value of the application server.
One transmission device may be connected to one application server, or may be connected to a plurality of application servers.
Illustratively, as shown in fig. 1, the transmission device 111 connects the application server 121, the transmission device 112 connects the application server 121, the application server 122, and the application server 123, and the transmission device 113 connects the application server 121 and the application server 122.

For example, the transfer device 111 is connected only to the application server 121, the transfer device 112 is connected only to the application server 122, and the transfer device 113 is connected only to the application server 123.
The transmitting device (e.g., transmitting device 111 shown in fig. 1) may be a separate physical device, such as a server or a computer, for transmitting the financial transaction traffic to the application server. In the embodiment of the present application, the transmission device receives the financial transaction traffic sent by the terminal 101 through the internet 130, and further transmits the financial transaction traffic to the application server.

An application server, such as application server 121 shown in fig. 1, may be a stand-alone physical device, such as a server or a computer. The application server is used for processing the received financial transaction flow, for example, if the financial transaction flow received by the application server is data generated by the transfer of the terminal, the process of the application server for processing the financial transaction flow may be to reduce a corresponding amount of money on an account of the transfer party, increase a corresponding amount of money on an account of the receiving party, and feed back a transfer success message to the transfer party. In this embodiment of the present application, the application server may also be referred to as an application node, and the application server is configured to receive the financial transaction traffic sent by the transmission device and report the resource usage of the application server to the control device 110.
It should be understood that fig. 1 is an exemplary architecture diagram, and the number of devices included in the transaction system shown in fig. 1 is not limited (e.g., the number of terminals, the number of transmission devices, and the number of application servers). Also, the transaction system shown in fig. 1 may include other devices besides the device shown in fig. 1, which is not limited thereto.
Next, as shown in fig. 2, an embodiment of the present application provides a flow control method, which is executed by a control device, which may be the control device 110 in the transaction system 10 shown in fig. 1, and includes the following steps.
S201, the control device obtains a resource use value of the first application server.
The control device may obtain the resource usage value of the first application server in the following ways.
Mode 1, passive acquisition. In the banking system, the first application server may report its resource usage value to the control device periodically, so that the control device dynamically adjusts a delay of the financial transaction traffic to be transmitted to the application server according to the resource usage value of the application server, where the reporting period may be preset by a manager.
Mode 2, active acquisition. The control device may actively send a request message to the first application server, where the request message is used to instruct the first application server to report its resource usage value.
The resource usage value is used to indicate an occupancy of resources used by the first application server to process the financial transaction traffic, the resources including computing resources and storage resources. The computing resource may be a Central Processing Unit (CPU) resource of the first application server, the computing resource sample value may refer to a CPU occupancy rate sample value, the storage resource may be a memory resource of the first application server, and the storage resource sample value may refer to a memory usage rate sample value.
The first application server may be any one of N application servers included in the banking system.
S202, when the resource usage value is larger than or equal to the threshold value, the control device determines the delay of the financial transaction flow to be transmitted to the first application server according to the flow control model.
The control device determines whether a resource usage value of the first application server is greater than a threshold value and determines whether to delay transmission of the financial transaction traffic to the first application server. The threshold value is used to indicate the limit of resources that the first application server is allowed to occupy for processing the financial transaction, and may be set by a manager in advance.
If the resource usage value of the first application server is less than the threshold, it represents that the first application server is not currently in a busy state, and the control device does not need to adjust the rate of the financial transaction traffic transmitted to the first application server, that is, the control device does not need to control the transmission device to delay transmission of the financial transaction traffic to the first application server.
If the resource usage value of the first application server is greater than or equal to the threshold value, which represents that the first application server is currently busy, the control device may adjust a rate of transmitting the financial transaction traffic to the first application server, i.e., delay transmission of the financial transaction traffic to the first application server.
When the resource usage value of the first application server is the occupancy rate of the central processing unit of the first application server, the resource usage value of the first application server is greater than or equal to the threshold, which may be that the occupancy rate of the central processing unit of the first application server is greater than or equal to the occupancy rate threshold. For example, if the occupancy rate threshold is 90%, it may be understood that the resource usage value of the first application server is greater than or equal to the threshold if the occupancy rate of the central processing unit of the first application server is greater than or equal to 90%.
When the resource usage value of the first application server is the memory usage rate of the first application server, the resource usage value of the first application server is greater than or equal to a threshold, which may be that the memory usage rate of the first application server is greater than or equal to a usage rate threshold. For example, if the usage threshold is 90%, if the memory usage of the first application server is greater than or equal to 90%, it may be understood that the resource usage value of the first application server is greater than or equal to the threshold.
When the resource usage value of the first application server includes an occupancy rate and a memory usage rate of the central processing unit of the first application server, the resource usage value of the first application server is greater than or equal to a threshold, which may be that a sum of the occupancy rate and the memory occupancy rate of the central processing unit of the first application server is greater than or equal to the threshold. Illustratively, the resource usage value may be equal to (occupancy of central processor + memory usage) of the first application server/2. For example, if the threshold is 90%, if the occupancy rate of the central processing unit of the first application server is greater than or equal to 90% and the memory usage rate is greater than or equal to 90%, it may be understood that the resource usage value of the first application server is greater than or equal to the threshold.
It can be understood that the higher the occupancy rate and the memory usage rate of the central processing unit of the first application server are, the more busy the first application server is. If the resource usage value of the first application server is greater than or equal to the threshold value, the financial transaction traffic is continuously transmitted to the first application server at this time, which may cause the first application server to fail to process the received financial transaction traffic as soon as possible, and to feed back a response message to the terminal in time, resulting in transaction failure and affecting the customer experience.
Therefore, when the resource usage value of the first application server is greater than or equal to the threshold value, the control device can determine the delay of the financial transaction flow to be transmitted to the first application server according to the flow control model, so that the transmission device delays the transmission of the financial transaction flow to the first application server, the data volume of the financial transaction flow processed by the first application server is reduced, the first application server can process the received financial transaction flow as soon as possible, a response message is fed back to the terminal in time, and the transaction is guaranteed to be completed smoothly.
Optionally, before the control device determines whether the resource usage value is greater than or equal to the threshold, the control device may create a flow control model according to a supervised learning method, input the calculated resource sample value, the stored resource sample value, and the unit transaction amount sample value into the flow control model, and train parameters of the flow control model until errors of the delay and delay sample values output by the flow control model converge.
The control device controls the rate of transmitting the unit transaction amount sample value to the first application server according to the delay sample value, so that the first application server processes the unit transaction amount sample value based on the calculation resource sample value and the storage resource sample value to achieve the processing satisfaction degree.
The unit transaction amount may refer to a transaction amount per unit time (e.g., 1 second), that is, an amount of data accessing the first application server per unit time, or an amount of data processed by the first application server per unit time. The unit transaction amount sample value may refer to a collection of transaction amounts for different units of time.
The calculation resource sample value may refer to a set of different calculation resource occupancy rates corresponding to the first application server when processing financial transaction traffic in different unit times.
The storage resource sample value may refer to a set of different storage resource usage rates corresponding to the first application server when processing financial transaction traffic in different unit times.
The delay sample value may refer to a set of delay times generated by the first application server in case of processing financial transaction traffic in different units of time.
Exemplarily, the application server 121 in fig. 1 is taken as an example for illustration. For the application server 121, an automatic testing tool is used to simulate a situation that the transaction pressure is increasing continuously, that is, a situation that the financial transaction traffic received by the application server 121 is increasing continuously, and the financial transaction traffic is continuously sent to the application server 121 to obtain sample data. Further, a transaction information table shown in table 1 below can be obtained.
TABLE 1
The judgment rule of the transaction satisfaction degree may be that under different unit transaction amounts, the response time of the application server to the financial transaction traffic is within 5 seconds (S), and the transaction success rate is 100%, which may be considered as satisfaction. If the response time of the application server to the financial transaction flow exceeds 5s and/or the success rate does not reach 100%, the application server can be determined to be unsatisfactory.
Next, the entries with satisfactory transaction satisfaction are selected, and the sample data table shown in Table 2 below is obtained.
TABLE 2
As can be seen from table 2, when the transaction satisfaction is satisfactory, a specific unit transaction amount, cpu occupancy, and memory usage rate may correspond to a specific delay time, and the following formula (1) may be satisfied.
T=A*Xtps+B*Xcpu+C*XramFormula (1)
Wherein T is a delay time, XtpsIs unit transaction amount, XcpuAs cpu occupancy, XramIs the memory usage rate.
And A, B, C three parameters need to be calculated to complete the training of the flow control model. A. B, C three parameters, also referred to as flow control model parameters, may also be referred to as training factors.
Supervised learning is a machine learning task in which a function is inferred from labeled training data. The training data includes a set of training examples. In supervised learning, each instance consists of an input object (usually a vector) and a desired output value (also called a supervisory signal). Supervised learning algorithms analyze the training data and produce an inferred function that can be used to map out new instances. An optimal solution would allow the algorithm to correctly determine class labels for those instances that are not visible. This requires that the learning algorithm be formed in a "rational" manner from a point of view of the training data to a point of view that is not visible.
After the flow control model is created by the supervised learning method, A, B, C the initial values of the three parameters are random numbers. According to table 2, the cpu occupancy rate sample value, the memory usage rate sample value, and the unit transaction amount sample value included in the sample data are input to the flow control model, and one delay time can be calculated. Comparing the calculated delay time with the sample delay time in table 2 to obtain an error, training A, B, C three flow control model parameters according to a back propagation algorithm and the error, continuously updating A, B, C three flow control model parameters, continuously reducing the error between the calculated delay time and the sample delay time, and finally calculating proper A, B, C three flow control model parameters, so that the error between the calculated delay time and the sample delay time output by the flow control model is completely converged, namely the error is within an acceptable range, completing the training of the flow control model, and obtaining the flow control model.
The back propagation algorithm (BP algorithm) is mainly repeated and circularly iterated by two links (excitation propagation and weight updating) until the output data reaches a preset target range after the flow control model acquires sample data. In the embodiment of the present application, the error between the calculated delay time and the sample delay time calculated by the trained A, B, C flow control model parameters for the input sample data is within the target range.
After the flow control model is obtained, the resource usage value and the unit transaction amount of the first application server may be input into the flow control model, and then the delay time, i.e., the delay time, for transmitting the financial transaction flow to the first application server is calculated through the flow control model.
S203, the control device sends a control instruction to the first transmission device.
And the control equipment sends the control instruction to a first transmission equipment in M transmission equipment connected with N application servers in the bank system, and the control instruction is used for instructing the first transmission equipment to send financial transaction flow to the application server according to the calculated delay.
The first transmission device may be a transmission device in the banking system that is connected to the first application server.
If the first application server is connected with only one transmission device, the transmission device connected with the first application server is the first transmission device.
Exemplarily, in connection with the transaction system shown in fig. 1, assuming that the resource usage value of the application server 123 is greater than the threshold value, since the application server 123 is connected only to the transmission device 112, the control device 110 sends a control instruction to the transmission device 112, and controls the transmission device 112 to transmit the financial transaction traffic to the application server 123 according to the indicated delay.
If the first application server is connected to a plurality of transmission devices, the first transmission device may be any one of the plurality of transmission devices.
Exemplarily, in connection with the transaction system shown in fig. 1, assuming that the resource usage value of the application server 121 is greater than the threshold value, and the application server 121 connects the transmission device 111, the transmission device 112, and the transmission device 113, the first transmission device may be any one of the three transmission devices of the transmission device 111, the transmission device 112, and the transmission device 113. Illustratively, the control device 110 may send control instructions to the transmission device 111 to control the transmission device 111 to send financial transaction traffic to the application server 121 according to the indicated delay.
S204, the first transmission equipment receives the control instruction sent by the control equipment.
And S205, the first transmission equipment sends the financial transaction flow to the first application server according to the delay indicated by the control instruction.
And after receiving the control instruction, the first transmission equipment sends the financial transaction flow to the first application server according to the delay indicated by the control instruction.
With reference to the transaction system shown in fig. 1, if the first transmission device is the transmission device 111, the first application server is the application server 121, and the delay time indicated by the control command is 1 s. The transfer device 111 transmits the financial transaction traffic to the application server 121 after a delay of 1s after receiving the control instruction transmitted by the control device 110.
Based on the embodiment shown in fig. 2, the control device adjusts the rate of the financial transaction traffic transmitted from the transmission device to the application server according to the resource usage of the application server and the supervised learning method, that is, when the application server processes a large amount of financial transaction traffic, the control device delays the transmission of the financial transaction traffic to the application server, so as to reduce the financial transaction traffic processed by the application server within a certain time, so that the application server can process the received financial transaction traffic as soon as possible based on its own hardware resources, and further feed back a response message as soon as possible, thereby ensuring that the transaction is completed smoothly. The situations that the application server cannot process the received financial transaction flow as soon as possible due to insufficient hardware resources of the application server when facing a large amount of financial transaction flow, and the transaction is slow, the response is overtime and even the application server is down are avoided.
A flow control method provided in an embodiment of the present application is described below with reference to a specific example.
Illustratively, as shown in fig. 3, the transmission device 111 is connected to the application server 121, the transmission device 112 is connected to the application server 122, and the transmission device 113 is connected to the application server 123. If the resource usage values of the application server 122 and the application server 123 are greater than the threshold, the unit transaction amount of the application server 122 is 150, the cpu occupancy rate is 60%, and the memory usage rate is 50%, the unit transaction amount of the application server 123 is 190, the cpu occupancy rate is 90%, and the memory usage rate is 70%, and the resource usage values and the unit transaction amount of the application server 122 and the application server 123 are input into the flow control model, so that the following table 3 can be obtained.
TABLE 3
As can be seen from table 3, the delay of the financial transaction traffic to be transmitted to the application server 122 calculated by the traffic control model is 3s, and the delay of the financial transaction traffic to be transmitted to the application server 123 is 4 s.
In turn, the control device 110 sends a first control instruction to the transmission device 112, instructing the transmission device 112 to send the financial transaction traffic to the application server 122 according to the delay time indicated by the first control instruction. The control device 110 sends a second control instruction to the transmission device 113, instructing the transmission device 112 to send the financial transaction traffic to the application server 123 according to the delay time indicated by the second transmission instruction.
The transmission device 112 sends the financial transaction traffic to the application server 122 according to the delay time indicated by the first control instruction, that is, after waiting for 3s, sends the financial transaction traffic to the application server 122.
The transmission device 113 sends the financial transaction traffic to the application server 123 according to the delay time indicated by the second control instruction, that is, after waiting for 4s, sends the financial transaction traffic to the application server 122.
The transaction system shown in fig. 1 includes a control device, and in a possible embodiment, the transaction system does not include the control device, and the function of the control device may be combined with the function of the transmission device on the same physical device, that is, the transmission device may also have the function of the control device, that is, the transmission device may be regarded as a control device. Illustratively, as shown in fig. 4, the embodiment of the present application provides a schematic structural diagram of another transaction system.
The transaction system 40 includes at least one terminal (such as the terminal 401 and the terminal 402 shown in fig. 4), the internet 430, and a banking system 41. Banking system 41 includes M transport devices (e.g., transport device 411, transport device 412, and transport device 413) and N application servers (e.g., application server 421, application server 422, and application server 423).
The transmission device 411 connects the transmission device 412 and the application server 421, and the transmission device 412 connects the transmission device 413, the application server 421, the application server 422, and the application server 423. The transmission device 413 is connected to the application server 423.
For the description of the terminal, the internet 430, the banking system 41, the transmission device and the application server, reference may be made to the above description of the terminal, the internet 130, the banking system 11, the transmission device and the application server in fig. 1, and no further description is given here. Fig. 4 differs from fig. 1 in that it is assumed that the transmission apparatus 412 has the function of a control apparatus, that is, the transmission apparatus 412 is a transmission apparatus having the function of a control apparatus. The transmission apparatus 412 needs to be connected with each application server in the banking system 41, that is, the transmission apparatus 412 is connected with the application server 421, the application server 422, and the application server 423.
Transport apparatus 412 may obtain resource usage values for application server 421, application server 422, and application server 423.
Assuming that the resource usage value of the application server 422 is greater than the threshold, since the application server 422 is connected to only the transmission device 412, the transmission device 412 may transmit the financial transaction traffic to the application server 422 according to the delay after determining the delay of the financial transaction traffic to be transmitted to the application server 422 by the transmission device 412 according to the traffic control model.
It is assumed that the resource usage value of the application server 421 is greater than the threshold value, since the application server 421 connects the transmission device 411 and the transmission device 412. Therefore, after the transmission device 412 determines the delay of the financial transaction traffic to be transmitted to the application server 422 according to the traffic control model, the transmission device 412 may transmit the financial transaction traffic to the application server 421 according to the delay.
The transmitting device 412 may also send control instructions to the transmitting device 411 to control the transmitting device 411 to transmit the financial transaction traffic to the application server 421 according to the indicated delay.
In one possible embodiment, the control device may allocate the financial transaction traffic based on a magnitude relationship of the resource usage value of each application server to a threshold value. Specifically, the control device preferentially allocates the financial transaction traffic to the application server having the resource usage value smaller than the threshold value without allocating the financial transaction traffic to the application server having the resource usage value greater than or equal to the threshold value.
Illustratively, the example is given by taking the control device as an example to connect the first application server and the second application server.
The control device obtains resource usage values of the first application server and the second application server, and if the resource usage value of the first application server is greater than a threshold value, the resource usage value of the second application server is smaller than the threshold value, that is, the resource usage value of the first application server is greater than the resource usage value of the second application server, it can be understood that the busy degree of the first application server is greater than the busy degree of the second application server. The financial transaction traffic may be distributed to and processed by the second application server. Specifically, the control device may send a control instruction to a transmission device connected to the second application server, the transmission device being controlled to send the financial transaction traffic to the second application server.
It can be understood that if the resource usage of the first application server is not considered, the financial transaction traffic is still allocated to the first application server, which may cause slow transaction, response timeout, or even downtime of the first application server due to insufficient hardware resources of the first application server, and the received financial transaction traffic cannot be processed in time, resulting in transaction failure and affecting customer experience.
