Description

Technical Field

[0001] The present invention relates to the field of flow control technology, and in particular to a flow control method, device, equipment, medium and product. Background Art

[0002] In high-concurrency scenarios and with limited resources, the trading system has a maximum transaction capacity. Exceeding this capacity can lead to abnormalities such as decreased transaction success rates or increased transaction response times. To prevent the system from accepting transactions exceeding the maximum transaction capacity, the system introduces a rate limiting control module to limit the number of transactions per unit time, thereby ensuring stable system operation.

[0003] Conventional rate limiting often simply sets a maximum permissible traffic threshold, limiting transaction volume to that value during peak trading hours. Alternatively, the system can monitor transaction volume, success rate, and response time, alerting system operators when these thresholds are exceeded. These operators can then reset the rate limiting threshold.

[0004] However, this approach of simply setting a maximum permissible traffic threshold often impacts critical system transactions during peak trading hours. Because the traffic limit threshold is fixed or can only be adjusted manually, when an internal system anomaly causes service performance degradation, the threshold cannot be lowered in a timely manner, potentially leading to further system overload and eventual partial or complete system failure.

[0026] Example 1

[0027] Figure 1 A flow chart of a flow control method is provided for the first embodiment of the present invention. This embodiment is applicable to dynamic flow limiting of different transaction services. The method can be executed by a flow control device, which can be implemented in the form of hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0028] S110. Obtain system status monitoring data and transaction services.

[0029] In this embodiment, system status monitoring data can be understood as the results obtained from testing the system's software and hardware. For example, it may include the CPU utilization, memory utilization, and disk utilization of different servers in the system, such as application servers and database servers. Transaction services can be understood as transaction processing-related data received by the system. For example, it may include system transaction volume, transaction response time, and upstream system transaction volume and response time.

[0030] Specifically, the processor can detect the system software and hardware status and the transaction status of upstream and downstream systems in real time to obtain system status monitoring data and transaction services.

[0031] S120: Determine flow limit threshold adjustment information and control the flow of each transaction service based on the transaction attribute information of the transaction service and the system status monitoring data.

[0032] In this embodiment, the transaction attribute information can be understood as the attributes of each transaction, such as the system performance consumption corresponding to different transaction types. The flow limit threshold adjustment information can be understood as the flow adjustment parameter value that should be set for different transactions.

[0033] Specifically, the processor can determine whether the current system state is abnormal based on system status monitoring data and adjust the current limit when an anomaly exists. The processor can combine the resource anomaly indicator with the transaction attribute information of the transaction service to calculate the current current limit control threshold for the relevant transaction and provide the current limit control threshold to the current limit control module in the system.

[0034] The technical solution of the embodiments of the present invention obtains system status monitoring data and transaction services; based on the transaction attribute information of the transaction services and the system status monitoring data, it determines the flow control threshold adjustment information and controls the flow of each transaction service. By monitoring the status of the system hardware and software and the status of the transaction services of upstream and downstream systems in real time, the system flow control threshold is dynamically adjusted in real time based on the monitoring results, achieving an optimal match between the system flow control threshold and the system status, thereby maximizing the stability of system operation and the service capacity of the system.

[0035] Furthermore, based on the above embodiment, the steps of determining flow limit threshold adjustment information and controlling the flow of each transaction service according to the transaction attribute information of the transaction service and the system status monitoring data specifically include:

[0036] Determine the adjustment range of the flow limiting threshold based on the system status monitoring data and the status threshold set; determine the flow limiting configuration items of the transaction service based on the transaction attribute information of the transaction service; determine the flow limiting threshold adjustment information and control the traffic of each transaction service based on the threshold adjustment mode, the flow limiting threshold adjustment range and the flow limiting configuration items.

[0037] In this embodiment, the state threshold set can be understood as a set of upper threshold values ​​allowed for recording different system monitoring data. The rate limit threshold adjustment range can be understood as a value reflecting the speed of adjustment to the threshold. The rate limit configuration item can be understood as data used to determine the rate limit adjustment value for each transaction. The threshold adjustment mode can be understood as the method used to specify how the rate limit threshold is adjusted.

[0038] Specifically, the processor can first determine whether the system currently has abnormal monitoring data based on the system status monitoring data and the status threshold set, and then determine the adjustment range of the flow control threshold based on the abnormal monitoring data. Based on the transaction attribute information of the transaction service, the processor can group related transactions and determine the flow control configuration items for each transaction service belonging to the different groups based on the attributes of each transaction group. Based on the threshold adjustment mode, the flow control threshold adjustment range, and the flow control configuration items, the processor can determine the flow control threshold adjustment information and control the flow of each transaction service.

[0039] For example, the status thresholds centrally record the upper and lower limits allowed for different system status monitoring data, as well as the minimum duration. For example, the upper limit allowed for the local machine's CPU usage is 80%, and the minimum duration is 30 seconds. If the CPU usage briefly exceeds 80% within 30 seconds, no action is taken. However, if the CPU usage exceeds 80% and persists for more than 30 seconds, an adjustment to the current limiting control threshold is triggered.

[0040] Furthermore, based on the above embodiment, the steps of determining the flow limiting configuration items of the transaction service according to the transaction attribute information of the transaction service can be refined as follows:

[0041] Transaction services are grouped to obtain transaction groups; the group rate limiting configuration items of the transaction group are determined based on the group importance level and the group resource occupancy type mask of the transaction group; the step rate limiting threshold of the transaction service is determined based on the importance level of the transaction service and the transaction group to which it belongs; the rate limiting configuration items of the transaction service are determined based on the step rate limiting threshold and the group rate limiting configuration items.

[0042] In this embodiment, a transaction group can be understood as a grouping used to group related transactions into the same group for threshold adjustment. A group importance level can be understood as a representation of the importance of related transactions in different transaction groups to the entire system. For example, it can be represented by a number, with larger numbers indicating greater importance to the system and smaller numbers indicating lesser importance. A group resource usage type mask can be understood as a representation of the utilization of different system resources by each transaction group. For example, if transaction group 1 utilizes more CPU, less local memory, and more local hard disk, the CPU resource usage type mask for transaction group 1 can be 100, the local memory resource usage type mask can be 30, and the local hard disk resource usage type mask can be 100. The resource usage type mask can be determined by pre-performance testing before the system is officially operational. For example, setting the system to process n transactions per second belonging to the transaction group and determining the system status and consumption after the system transactions stabilize. A stepped rate limiting threshold can be understood as different rate limiting thresholds for the same transaction. Group throttling configuration items reflect the throttling settings for different transaction groups. For example, they may include the maximum and minimum traffic allowed for each transaction group, the corresponding transaction list, and the transaction ratios for different transaction services within the list. For example, the list contains one or more transactions configured within a group, along with the traffic ratios for each transaction. For example, if a transaction list contains transactions T1 and T2 with ratios of 1 and 2, respectively, and the current throttling threshold for the group is 100 transactions per time unit, then the throttling threshold for transaction T1 is 100 * 1 = 100 transactions per time unit, and the throttling threshold for transaction T2 is 100 * 2 = 200 transactions per time unit. Ratios can be decimals but must be positive. The calculation formula in this example is for illustrative purposes only; different formulas and coefficients can be used.

[0043] Specifically, the processor can group transaction services to obtain transaction groups, and different transaction groups are distinguished by group IDs and names. The processor can determine the order of transaction groups for adjusting the flow limiting threshold according to the group importance level of the transaction group, that is, give priority to adjusting the flow limiting value of the transaction corresponding to the group with a low importance level. The processor can determine the flow limiting amplitude and maximum traffic value of the transaction group relative to different system states through the group resource occupancy type mask, and use the order, flow limiting amplitude and target value of the transaction group adjustment as the group flow limiting configuration item for each transaction. The processor can determine the different importance levels and corresponding maximum traffic values ​​of the transaction service in different transaction groups according to the importance level of the transaction service and the transaction group to which it belongs, and use the order and different maximum traffic values ​​as the step flow limiting threshold. The processor can determine the flow limiting configuration item of the transaction service according to the step flow limiting threshold and the group flow limiting configuration item.

[0044] For example, each transaction group pre-sets the maximum allowed flow rate for the group and the minimum allowed flow rate for the group. These two configuration items determine the upper and lower limits of the current flow control threshold of the transaction group. Usually, when resources are sufficient and the system is operating normally, the current flow control threshold of the transaction group = the maximum allowed flow rate of the group. When system resources are tight, the current flow control threshold of the transaction group will be reduced to the minimum allowed flow rate setting value of the group. The maximum allowed flow rate of the group ≧ the minimum allowed flow rate of the group ≧ 0. Taking the settings in Table 1 below as an example, you can see that the transactions in groups ID01 and ID03 are the same, but the importance level and minimum allowed flow rate are different. This configuration can achieve step-by-step flow control for specific transactions. When system resources are tight, the processor will give priority to lowering the flow control threshold of transaction T1 in group ID03 until it is reduced to 20. During this process, the processor can calculate that the traffic value for transaction T1 corresponding to ID01 is 100, the traffic value for transaction T2 corresponding to ID02 is 100, and the traffic value v for transaction T1 corresponding to ID03 is less than 100 but greater than or equal to 20. Since there are multiple traffic values ​​for T1, the processor will take the minimum value. If the traffic for transaction T1 drops to 20 but system resources are still limited, the processor will further reduce the traffic for transaction T2 corresponding to group ID02. If the traffic for transaction T2 drops to 20 but system resources are still limited, the processor will further reduce the traffic for transaction T1 corresponding to group ID01 until the traffic is reduced to 0.

[0047]

[0048] Furthermore, based on the above embodiment, the steps of determining the current limiting threshold adjustment information and controlling the traffic of each transaction service according to the threshold adjustment mode, the current limiting threshold adjustment range, and the current limiting configuration items can be further refined as follows:

[0049] When the threshold adjustment mode is the first mode, the current limiting threshold in the current limiting configuration item is used as the current limiting threshold adjustment information and the traffic of each transaction service is controlled; when the threshold adjustment mode is the second mode, the adjustment unit for each adjustment is determined according to the set number of adjustments and the current limiting configuration item and used as the current limiting threshold adjustment information and the traffic of each transaction service is controlled; when the threshold adjustment mode is the third mode, the current limiting threshold adjustment information is determined according to the set fixed adjustment value and the current limiting configuration item and the traffic of each transaction service is controlled; when the threshold adjustment mode is the fourth mode, the current adjustment range is determined according to the current limiting threshold adjustment range and the current limiting configuration item and used as the current limiting threshold adjustment information and the traffic of each transaction service is controlled.

[0050] In this embodiment, the first mode can be understood as a mode in which the flow rate is directly adjusted to the flow limit threshold. The flow limit threshold can be understood as the minimum allowable flow rate for different transaction services. The second mode can be understood as a fixed-number adjustment mode, where the set number of adjustments is the number of times the flow rate is adjusted to the flow limit threshold. The adjustment unit can be understood as the unit value of the flow rate adjusted each time. The third mode can be understood as a fixed-interval mode, where the flow rate adjusted each time is set by setting a fixed adjustment value. The fourth mode can be understood as a mode in which adjustments are made based on the variation range of different monitoring data. The current adjustment range can be understood as the range of each adjustment.

[0051] Specifically, when the threshold adjustment mode is the first mode, and it is detected that the flow control threshold of the transaction needs to be lowered, the processor can use the flow control threshold in the flow control configuration item as the flow control threshold adjustment information, that is, the processor can directly take the minimum value that can be adjusted for adjustment. When the flow control threshold of the transaction needs to be restored, the maximum value that can be adjusted is directly taken for adjustment. When the threshold adjustment mode is the second mode, the processor can determine the adjustment unit for each adjustment based on the set number of adjustments and the flow control configuration item and use it as the flow control threshold adjustment information to control the flow of each transaction service. For example, if the maximum allowed flow is 100, the minimum allowed flow is 0, and the number of adjustments is 5, then each adjustment is (100-0) / 5=20 units. When the threshold adjustment mode is the third mode, the processor can determine the flow control threshold adjustment information and control the flow of each transaction service according to the set fixed adjustment value combined with the resource occupancy type mask in the flow control configuration item. When the threshold adjustment mode is the fourth mode, the processor can determine the current adjustment range according to the current limiting threshold adjustment range and the current limiting configuration item and use it as the current limiting threshold adjustment information to control the flow of each transaction service, and continue to monitor the current system status monitoring data after control to determine whether the target value in the current limiting configuration item is reached, and then determine the current adjustment range of the second adjustment and use it as the current limiting threshold adjustment information to control the flow of each transaction service, and so on until the target value is reached. Among them, the threshold adjustment mode can also limit the flow of related transactions according to specific dimensions, such as provincial and municipal dimensions, transaction channels (mobile banking, online banking and outlets, etc.) dimensions. When processing, transactions of different dimensions are processed as different transactions. In this case, this solution is still applicable. The corresponding transaction identification and differentiation components can be designed during program development, and the same transaction of different dimensions can be mapped into different transactions. Transaction grouping can be configured for the mapped transactions, and then loaded and called by the status monitoring module to support it.

[0052] Among them, based on the above embodiment, the steps of determining the current adjustment range and the flow of each transaction service as the flow control threshold adjustment information based on the flow control threshold adjustment range and the flow control configuration items can be refined as follows:

[0053] According to the adjustment range of the current limiting threshold and the resource occupancy type mask in the current limiting configuration item, the current adjustment threshold is determined as the current limiting threshold adjustment information and controlled; when adjustment is made according to the current adjustment threshold and the set interval condition is met, the current system status monitoring data is obtained; if the current system status monitoring data does not reach the target monitoring indicator value in the current limiting threshold adjustment information, the current adjustment threshold is determined as the current limiting threshold adjustment information for control according to the current system status monitoring data, the previous adjustment threshold, the resource occupancy type mask and the target monitoring indicator value, and the step of obtaining the current system status monitoring data is returned; otherwise, the adjustment is ended.

[0054] In this embodiment, the set interval condition can be understood as a condition for determining whether to perform the next adjustment, such as a set time interval or a set system status reduction value. The target monitoring indicator value can be understood as an indicator value set by the system without current limiting adjustment. For example, if the current abnormal indicator is CPU usage, the target monitoring indicator value is 70% CPU usage. The previous adjustment threshold can be understood as the adjustment threshold set during the previous adjustment.

[0055] Specifically, the processor can determine the current adjustment threshold as the current limiting threshold adjustment information and control it based on the current limiting threshold adjustment range and the resource occupancy type mask in the current limiting configuration item; when adjustment is made based on the current adjustment threshold and the set interval condition is met, the current system status monitoring data is obtained; if the current system status monitoring data does not reach the target monitoring indicator value in the current limiting threshold adjustment information, the current adjustment threshold is determined as the current limiting threshold adjustment information for control based on the current system status monitoring data, the previous adjustment threshold, the resource occupancy type mask and the target monitoring indicator value, and the step of obtaining the current system status monitoring data is returned; otherwise, the adjustment is ended.

[0056] For example, the target monitoring indicator is set to 70% CPU usage, the upper limit is allowed to be 90%, the allowable deviation is adjusted to 2%, the maximum allowable flow is 100, the minimum allowable flow is 0, and the first adjustment amplitude coefficient is 0.4. When the CPU usage exceeds 90%, the first flow control threshold is reduced by (100-0)*0.4=40. After the first adjustment, the CPU usage is reduced to 74%. Based on the first indicator change amplitude and the amplitude of the distance from the indicator target value, the second flow control threshold is reduced by 40*((74%-70%) / (90%-74%))=10. After the second adjustment, the CPU usage is reduced to 66%. Based on the second indicator change amplitude and the amplitude of the distance from the indicator target value, the third flow control threshold is reduced by 10*((66%-70%) / (74%-66%))=-5, which is a callback of 5 units. After the third adjustment, the CPU usage returns to 72%, which is within the allowable range of 70%±2%, and no further adjustment is made. The calculation formula in the example is only an example. Different calculation formulas can be used and different calculation coefficients can be introduced.

[0057] Exemplarily, taking the settings in Table 2 as an example, transaction groups ID01, ID02 and ID03 have the same importance level. When the processor detects that the database CPU usage exceeds the limit, it will try to adjust the current limiting control thresholds of ID01, ID02 and ID03. If the "resource occupancy type mask" is not considered, the processor calculates that the current limiting control threshold of each group needs to be reduced by 20 units. Then, based on the trigger condition of the database CPU usage exceeding the limit, the "database CPU" mask value in the "resource occupancy type mask" is comprehensively considered to obtain the final current limiting control threshold reduction value of each group: ID01 group is 20*100 mask value (%) = 20 units; ID02 group is 20*30 (%) = 6 units; ID03 group is 20*0 (%) = 0 unit. If both the database CPU usage and local memory usage exceed the limit, the "Database CPU" mask value and the "Local Memory" mask value in the "Resource Usage Type Mask" are considered together to determine the final rate limiting control threshold reduction for each group: 20*(100+30)(%)=26 units for group ID01; 20*(30+70)(%)=20 units for group ID02; and 20*(0+100)(%)=20 units for group ID03. The calculation formula in this example is for reference only; different calculation formulas and coefficients can be used.

[0059]

[0060] The technical solution of the embodiment of the present invention can achieve dynamic adjustment of system transaction traffic without manual intervention through real-time monitoring of the system resource usage status. When the system resource usage rate is abnormal, the system resource usage rate can be automatically restored to the normal range by reducing the traffic of system-related transactions in a targeted manner. Through the transaction grouping method, on the one hand, differentiated configuration of different transactions can be achieved, thereby achieving precise transaction traffic control. On the other hand, the configuration of similar transactions can be simplified, and repeated configuration of the same transaction can be supported, and step-by-step traffic adjustment can be achieved to cope with more complex system external service requirements. By introducing resource occupancy type masks, targeted flow control of specific resource anomalies can be achieved, thereby achieving precise resource occupancy release and ensuring the service efficiency of the system to a greater extent (allowing more transaction traffic under the premise of ensuring that the system resource usage does not exceed the limit). Adaptive matching of transaction traffic and system status is achieved, thereby further improving the robustness of the system.

[0061] As a first optional embodiment of the first embodiment, after controlling the flow of each transaction service according to the flow limiting threshold adjustment information, the following further comprises:

[0062] When the threshold recovery conditions are reached, recovery adjustment information is determined and adjusted based on the current system status monitoring data and transaction services.

[0063] In this embodiment, the threshold restoration condition can be understood as a condition for determining whether the threshold restoration can be performed, such as the system status is normal and the set cooling time has been reached, etc. The restoration adjustment information can be understood as a method for controlling how to perform current limiting restoration.

[0064] Specifically, when threshold recovery conditions are met (e.g., when current system status monitoring data is within the normal range and remains within the normal range for a period of time), the processor can perform flow control recovery based on the attributes of the transaction service and the set threshold adjustment mode. For example, in the first mode, the transaction service flow rate is directly adjusted to the maximum value that can be achieved, while in the second mode, multiple adjustments are made based on the number of adjustments and the maximum allowable flow rate.

[0065] In a first optional embodiment of the first embodiment, by setting a threshold recovery mode, automatic recovery of the system transaction flow after being restricted can be achieved without manual intervention.
