Specifically, the input unit 130 may include a touch screen 131 (optional) and / or other input devices 132.

It is also used for the storage of multimedia files, and the storage of running programs and applications.
[0055] The processor 170 is the control center of the terminal 100. It uses various interfaces and lines to connect various parts of the entire terminal 100. By running or executing instructions stored in the memory 120 and calling data stored in the memory 120, it executes various functions of the terminal 100 and processes data, thereby controlling the terminal device as a whole. Optionally, the processor 170 may include one or more processing units; preferably, the processor 170 may integrate an application processor and a modem processor, wherein the application processor mainly processes the operating system, user interface and application program, and the modem processor mainly processes wireless communication. It is understandable that the above-mentioned modem processor may not be integrated into the processor 170. In some embodiments, the processor and the memory may be implemented on a single chip, and in some embodiments, they may also be implemented separately on separate chips. The processor 170 may also be used to generate corresponding operation control signals, send them to corresponding components of the computing and processing device, read and process data in the software, especially read and process data and programs in the memory 120, so that each functional module therein performs corresponding functions, thereby controlling the corresponding components to act according to the requirements of the instructions.
[0056] The radio frequency unit 110 (optional) can be used for receiving and sending information or receiving and sending signals during a call, for example, after receiving the downlink information of the base station, it is sent to the processor 170 for processing; in addition, the designed uplink data is sent to the base station. Generally, the RF circuit includes but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier (Low Noise Amplifier, LNA), a duplexer, etc. In addition, the radio frequency unit 110 can also communicate with network devices and other devices through wireless communication.

[0057] In this embodiment of the present application, the radio frequency unit 110 can send transaction current limiting parameter data to the server 200 and receive the current limiting processing result sent by the server 200.
[0058] It should be understood that the radio frequency unit 110 is optional and can be replaced by other communication interfaces, such as a network port.
[0059] The terminal 100 also includes a power supply 190 (such as a battery) for supplying power to various components. Preferably, the power supply can be logically connected to the processor 170 through a power management system, so that the power management system can manage functions such as charging, discharging, and power consumption.
[0060] The terminal 100 further includes an external interface 180 , which may be a standard Micro USB interface or a multi-pin connector, and may be used to connect the terminal 100 to communicate with other devices, or to connect a charger to charge the terminal 100 .

Some or all of the methods described below may be applied in the following embodiments. Figure 2 In the terminal 100 shown.
[0062] Next describe Figure 1 The product form of the server 200;
[0063] Figure 3 A structural diagram of a server 200 is provided, such as Figure 3 As shown, the server 200 includes a bus 201, a processor 202, a communication interface 203, and a memory 204. The processor 202, the memory 204, and the communication interface 203 communicate with each other via the bus 201.
[0064] The bus 201 may be a peripheral component interconnect (PCI) bus or an extended industry standard architecture (EISA) bus. The bus may be divided into an address bus, a data bus, a control bus, etc. For ease of representation, Figure 3 Only one thick line is used in the diagram, but this does not mean that there is only one bus or only one type of bus.
[0065] The processor 202 may be any one or more of a central processing unit (CPU), a graphics processing unit (GPU), a microprocessor (MP), or a digital signal processor (DSP).
[0066] The memory 204 may include a volatile memory, such as a random access memory (RAM). The memory 204 may also include a non-volatile memory, such as a read-only memory (ROM), a flash memory, a hard disk drive (HDD), or a solid state drive (SSD).
[0067] Among them, the memory 204 can be used to store software codes related to the transaction flow limiting method, the processor 202 can execute the steps of the transaction flow limiting method of the chip, and can also schedule other units to implement corresponding functions.
[0068] It should be understood that the above-mentioned terminal 100 and server 200 can be centralized or distributed devices, and the processors in the above-mentioned terminal 100 and server 200 (such as processor 170 and processor 202) can be hardware circuits (such as application specific integrated circuit (ASIC), field-programmable gate array (FPGA), general-purpose processor, digital signal processor (DSP), microprocessor or microcontroller, etc.), or a combination of these hardware circuits. For example, the processor can be a hardware system with an instruction execution function, such as a CPU, DSP, etc., or a hardware system without an instruction execution function, such as an ASIC, FPGA, etc., or a combination of the above-mentioned hardware systems without an instruction execution function and hardware systems with an instruction execution function.
[0069] At present, most application systems will set a flow limit threshold. When the system access traffic reaches the threshold, the predetermined flow limit rules will be triggered to limit the system traffic at a fixed ratio. However, canceling the flow limit or adjusting the flow limit ratio requires human intervention. This one-size-fits-all flow limit method will not only waste resources, but also affect user experience.
[0070] In order to solve the above problems, the present application embodiment provides a transaction flow limiting method. The transaction flow limiting method of the present application embodiment is described in detail below with reference to the accompanying drawings.
[0071] Reference Figure 4 , Figure 4 A flow chart of a transaction flow limiting method provided in an embodiment of the present application is shown as follows: Figure 4 As shown, a transaction flow limiting method provided in an embodiment of the present application may include steps 401 to 404, and these steps are described in detail below.
[0072] 401. Determine whether the target transaction has currently triggered the current limiting process.
[0073] Specifically, the target transaction here can be a transaction that needs to be processed in the daily operation of the bank, such as a transfer, remittance, etc. The transaction flow (unit: transaction) of the target transaction in a unit time can be counted, and the statistical result can be compared with the preset flow limit threshold to determine whether the flow limit processing of the target transaction is triggered.
[0074] For example, for remittance transactions, if it is detected that the transaction volume of the remittance transactions in a certain application is 55,000 transactions per minute, which exceeds the flow limit threshold of 50,000 transactions / minute, flow limit processing can be triggered.
[0075] It is understandable that those skilled in the art may also use other methods to determine whether to trigger the current limiting process, which is not limited here.
[0076] 402. If yes, determine the estimated traffic value after the flow limiting is restored according to the current transaction flow value after the flow limiting process and the current flow limiting ratio value, where the current flow limiting ratio value is the flow limiting ratio value preset for the target transaction.
[0077] Specifically, after determining to start the flow limiting process, the estimated flow value after the actual flow is restored is calculated based on the current transaction flow value and the current flow limiting ratio value obtained in real time. Specifically, the current transaction flow value can be divided by the current flow limiting ratio value to obtain the estimated flow value.
[0078] 403. If the estimated traffic value is not less than the preset flow limiting threshold, an updated flow limiting ratio value is determined based on the estimated traffic value and the target transaction traffic value. The target transaction traffic value is a preset maximum transaction traffic value allowed after flow limiting processing is performed on the target transaction.
[0079] Specifically, when the estimated flow is not less than the preset flow limiting threshold, that is, when it is determined that the estimated flow still triggers flow limiting processing, the flow limiting ratio value of the estimated flow is re-determined. Specifically, the target transaction flow value is divided by the estimated flow value to obtain the updated flow limiting ratio value. Therefore, when the updated flow limiting ratio value is used to limit the real-time transaction flow, the number of transactions to be limited can be maintained at the flow limiting ratio value before the update, and the determined flow limiting remains consistent.
[0080] 404. Determine the current limiting transaction according to the updated current limiting ratio value.
[0081] Specifically, the received code of the current transaction can be determined according to the updated current limiting ratio value and the preset current limiting ratio precision value. If the code is within the updated current limiting ratio value range of the target transaction, the current transaction is stopped and the corresponding current limiting prompt is returned.
[0082] The preset current limiting ratio precision value may include: none, one decimal place, two decimal places and other precision values. When actually limiting the current, the updated current limiting ratio value and current limiting ratio precision can be combined to generate a code of corresponding precision for each received transaction. If the code is within the current limiting ratio range, the transaction is limited and the corresponding current limiting prompt is returned. If the code is not within the current limiting ratio range, the transaction can be executed normally in the application system.
[0083] This transaction flow limiting method adjusts the flow limiting ratio used in the flow limiting control process in real time according to the current real-time transaction flow. Compared with the traditional one-size-fits-all flow control mode, it can provide better protection for the application system, while making full use of the existing resources of the system and avoiding the waste of service resources.
[0084] In a possible implementation, when the estimated flow value is less than the preset flow limit threshold, it can be determined whether to cancel the flow limit processing of the target transaction according to the estimated flow value and the preset recovery threshold. If the estimated flow value is less than the preset recovery threshold, the flow limit processing of the target transaction can be canceled.
[0085] The preset recovery threshold may be the same as the current limiting threshold or may be smaller than the current limiting threshold. The specific value may be set as required and will not be described in detail here.
[0086] As a specific application of the above embodiment, when setting the transaction flow limiting method in the server, refer to Figure 5 The system may specifically include: a current limiting configuration unit, an intelligent processing unit, a monitoring unit and a current limiting unit.
[0087] Current limiting configuration unit: mainly includes current limiting transaction configurator, current limiting rule configurator, monitoring time configurator, and warning information configurator. The current limiting transaction configurator is used to configure the transactions that need to be limited and the corresponding current limiting threshold (in units) and recovery threshold (in units); the current limiting rule configurator is used to configure the target number of transactions that can access the system normally after current limiting (in units) and the current limiting ratio accuracy (none, one decimal place, two decimal places); the monitoring time is used to configure the monitoring frequency (in units) which will affect the update frequency of the current limiting ratio; the warning information configurator is used to configure the warning information content and the information of the person who receives the warning.
[0088] Monitoring unit: mainly performs real-time statistics on the traffic involved in the transaction based on the flow-limiting transaction information and monitoring time configured by the user, and sends the statistical results to the intelligent processing unit.
[0089] Intelligent processing unit: mainly includes real-time traffic restorer, flow limiting ratio calculator, flow limiting restorer, and alarm. The real-time traffic restorer will receive the statistical results provided by the monitoring and alarm unit, and determine whether the corresponding transaction has been processed by flow limiting. If it has been processed by flow limiting, it will restore the actual traffic based on the current transaction traffic combined with the flow limiting ratio to obtain the estimated traffic (current transaction traffic / flow limiting ratio = estimated traffic); the flow limiting ratio calculator will calculate the flow limiting ratio based on the estimated traffic combined with the configured flow limiting rules (target number of transactions / estimated traffic = flow limiting ratio), and after obtaining the flow limiting ratio, it will start the flow limiting or update the current flow limiting ratio. If the flow limiting is newly started, it will trigger the alarm to send an alarm message to the corresponding receiving personnel; the flow limiting restorer will determine whether to cancel the flow limiting based on the estimated traffic combined with the recovery threshold. If the flow limiting is cancelled, it will trigger the alarm to send a recovery message to the corresponding receiving personnel.
[0090] Current limiting unit: Combined with the current current limiting ratio and current limiting ratio accuracy, it generates a code of corresponding accuracy for each transaction received by the system. If the code is within the current limiting ratio range, the transaction is limited and a current limiting prompt is returned. If the code exceeds the current limiting ratio range, the transaction can access the application system normally.
[0091] Specifically, the processing flow of the monitoring unit and the intelligent processing unit can refer to Figure 6 As shown in the figure, after the flow limiting is started, the real-time flow statistics are performed by reading the flow-limited transactions and monitoring the timeliness. When the transaction flow limiting is determined, the estimated flow is calculated. When the estimated flow is still greater than the flow limiting threshold, the flow limiting ratio is calculated. When the flow limiting monitoring of the current transaction is not started for the first time, the flow limiting ratio is updated. When the flow limiting monitoring of the current transaction is started for the first time, the flow limiting process can be directly triggered and an early warning message can be sent.
[0092] When the estimated flow rate is less than the recovery threshold, the flow limit can be cancelled and the corresponding recovery information can be sent.
[0093] The processing flow in the current limiting unit refers to Figure 7 As shown, when it is determined that the transaction is limited, the limiting ratio and the limiting ratio accuracy are obtained, and the corresponding accuracy code is generated according to the order of the current transaction. By judging whether the accuracy code is within the range of the limiting ratio, it is determined whether to limit the flow.
[0094] The above-mentioned current limiting method realizes automatic triggering of flow control, real-time adjustment of flow control ratio, automatic recovery of flow control, and early warning message reminder. It can provide strong protection when the application system traffic is too large, effectively improve the stability and robustness of the application system, and greatly reduce the operation and maintenance workload of system maintenance personnel.
