All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In this application, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
The cross-system flow limiting method and device provided by the invention can be used in the financial field or other fields, for example, can be used in the application scene of limiting flow in the financial field. Other fields are any other than financial fields, for example, cross-system current limiting fields. The foregoing is merely exemplary, and is not intended to limit the application field of the cross-system current limiting method and apparatus provided by the present invention.
The background technology shows that the front-end channel mainly combines the self condition to limit the access quantity, but cannot regulate the limit value of the access quantity by referring to the condition of the backward system, and the problem of limitation exists.
Therefore, the embodiment of the invention provides a cross-system current limiting method and device, when a transaction request with the type conforming to the preset current limiting transaction type is received, the current transaction transactional flow is obtained; judging whether the transaction traffic is in a preset current limiting range or not; if the current transaction flow is within the preset flow limiting range, acquiring the occupation ratio of the transaction flow of each backward system according to the system name; judging whether the occupation ratio of transactional traffic of each backward system is smaller than a preset value; if the ratio of the transactional traffic is smaller than the preset value, the preset current limiting range is adjusted according to the preset proportion. The transaction flow rate control method comprises the steps of obtaining the proportion value of the transaction flow rate of each backward system, adjusting a preset flow limit range according to the proportion condition, flexibly adjusting the flow limit value according to the whole transaction link, and improving the utilization rate of system resources to the greatest extent.
Referring to fig. 1, a flow chart of a cross-system current limiting method according to an embodiment of the present invention is shown, where the current limiting method includes:
it should be noted that the current limiting method is applicable to a front-end system facing the user and a backward system involved in each processing service.
Step S101: and when a transaction request with the type conforming to the preset current limiting transaction type is received, acquiring the current transaction traffic.
The system database stores a target data table, and the contents recorded in the target data table include: the transaction type of the set limit value, the transaction number corresponding to the transaction of the set limit value, the transaction time, the initial limit value corresponding to the transaction of the set limit value, the current transaction traffic (Transaction Per Second, TPS) of the front-end system at the transaction time, the transaction traffic of each backward system at the transaction time related to the transaction of the set limit value, and the ratio between the transaction traffic of each backward system at the transaction time and the maximum bearing value of the backward system.
For example: the "transaction type setting a current limit value" recorded in the target data table includes: and the types of receiving sports consumption coupons, receiving daily consumption money, purchasing food and drink and the like. The target data table also records: and acquiring information such as 12345 corresponding to the sports consumption ticket, 2022, 7, 1 and the like.
It will be appreciated that the type of transaction request received needs to be in accordance with a preset current limit transaction type, i.e. the "set current limit value transaction type" recorded in the target data table.
It will be appreciated that the transaction request contains at least: a user identifier corresponding to the user initiating the transaction request, and a system name of each backward system involved in processing the transaction request.
In the specific implementation process of step S101, when the front-end system receives a transaction request with a type conforming to a preset current-limiting transaction type, the current transaction traffic of the front-end system is obtained.
Step S102: and judging whether the transaction traffic is in a preset current limiting range or not. If the current transaction traffic is within the preset current limiting range, executing step S103; and if the current transaction flow is not in the preset flow limiting range, processing the transaction request according to the specific condition of the current transaction flow.
It should be noted that, after judging whether the current transaction traffic is within the preset current limiting range, performing related processing on the transaction request according to the judging result. The details of the implementation of processing the transaction request according to the determination result are shown in fig. 2 in the embodiment of the present invention.
It may be appreciated that the preset current limit range may be set according to an initial current limit value corresponding to a transaction type in which the current limit value is set in the target data table, for example: transaction type setting a limiting value: and (5) receiving a sports consumption ticket and an initial limit value: 100; the preset restriction range may be set to 100, 50.
In the specific implementation process of step S102, it is determined whether the current transaction transactional traffic of the front-end system is within a preset current limit range. If the current transaction flow is within the preset flow limiting range, further judging whether the flow limiting range needs to be adjusted, and executing step S103; if the current transaction traffic is not within the preset current limit range, the following corresponding operation needs to be confirmed according to the relationship between the current transaction traffic of the front-end system and the minimum value and the maximum value of the preset current limit range, which is shown in fig. 2 in detail in the embodiment of the present invention.
Step S103: and acquiring the occupation ratio of the transactional traffic of each backward system according to the system name.
In the specific implementation process of step S103, if the current transaction traffic is within the preset current limiting range, the occupation ratio of the transaction traffic of each backward system is obtained according to the system name included in the transaction request.
Specifically, the transaction request comprises system names of all backward systems involved in processing the transaction request, and current transactional flow and a maximum bearing value of each backward system are obtained according to the system names; and then calculating the proportion of the current transactional flow of each backward system in the maximum bearing value to obtain the proportion of the transactional flow of each backward system.
For example: in a transaction request for a sports consumer ticket, a backward system is involved comprising: a coupon system A and a bus inquiry system B. Acquiring the current transactional flow of the coupon system A and the maximum bearing value of the coupon system A, and calculating the proportion of the current transactional flow of the coupon system A in the maximum bearing value of the coupon system A to obtain the proportion of the transactional flow of the coupon system A; and obtaining the current transactional flow of the bus inquiry system B and the maximum bearing value of the bus inquiry system B, and calculating the proportion of the current transactional flow of the bus inquiry system B in the maximum bearing value of the bus inquiry system B to obtain the proportion of the transactional flow of the bus inquiry system B.
Step S104: and judging whether the occupation ratio of the transactional traffic of each backward system is smaller than a preset value. If the ratio of the transactional traffic is smaller than the preset value, executing step S105; if the duty ratio of any one of the transactional traffic is not less than the preset value, step S106 is executed.
In the specific implementation process of step S104, the duty ratio conditions of the transactional traffic of each backward system are synthesized, and whether the preset current limiting range needs to be adjusted or not is determined according to the duty ratio conditions; specifically, judging whether the ratio of transactional traffic of each backward system corresponding to the transaction request is smaller than a preset value; if the occupation ratio of the transactional traffic of each backward system is smaller than the preset value, executing step S105; if the ratio of the transactional traffic of any one of the backward systems is not less than the preset value, step S106 is executed.
In some embodiments, the preset value is a configurable parameter, for example, the preset value is 70%, and it is determined whether the ratio of the transactional traffic of each backward system is less than 70%.
Step S105: and adjusting a preset current limiting range according to a preset proportion.
In the specific implementation process of step S105, if the ratio of the transactional traffic of each backward system is smaller than the preset value, the preset current limiting range is adjusted according to the preset ratio.
It can be understood that if the ratio of the transactional traffic of each backward system is smaller than the preset value, such as 70%, it indicates that it is easier for each backward system to process the current transaction at present, and the initial limiting value can be increased to increase the utilization rate of the system resources. The initial current limit value is adjusted to be 1.1 times of the initial current limit value according to a preset ratio (such as 1:1.1). That is, assuming that the initial current limit value is 100, the initial current limit value is adjusted to 110; the preset restriction is adjusted to 110, 55.
Step S106: keeping the preset current limiting range unchanged.
In the specific implementation process of step S106, if the ratio of the transactional traffic of any one backward system is not less than the preset value, the preset current limiting range is kept unchanged.
It will be appreciated that if the ratio of transactional traffic of any one of the backward systems is not less than a predetermined value, such as 70%, then the backward systems are instructed to process the current transaction at a higher pressure, and it is not preferable to increase the initial limiting value. The initial current limiting value is kept unchanged, and the preset current limiting range is kept unchanged.
In the embodiment of the invention, the preset current limiting range is adjusted according to the situation of transactional traffic of each system in the actual business processing process: when the resource occupation condition of each system is less, the initial current limiting value is increased, so that the preset current limiting range is adjusted, the service availability of the system is increased, and the service requirement is met.
The specific implementation manner of performing related processing on a transaction request according to a determination result after determining whether the current transaction transactional flow is within the preset flow limiting range as referred to in fig. 1 in the above embodiment of the present invention is referred to in fig. 2, which shows a flowchart for processing a transaction request provided in the embodiment of the present invention, including:
step S201: and when a transaction request with the type conforming to the preset current limiting transaction type is received, acquiring the current transaction traffic.
It should be noted that, the specific implementation manner of the step S201 is the same as the implementation principle of the step mentioned in the step S101, and will not be described herein.
Step S202: and judging whether the transaction traffic is in a preset current limiting range or not. If the current transaction traffic is within the preset current limit range, executing step S204; if the current transaction traffic is not within the preset flow limit range, step S203 is executed.
In the specific implementation process of step S202, it is determined whether the current transaction transactional traffic of the front-end system is within a preset current limit range. If the current transaction traffic of the front-end system is within the preset current limiting range, executing step S204; if the current transaction traffic of the front-end system is not within the preset current limit range, step S203 is executed.
It should be noted that, the specific implementation manner of the step S202 is the same as the implementation principle of the steps mentioned in the step S102, and will not be repeated here.
Step S203: and judging whether the transaction traffic is smaller than the minimum value of the preset current limiting range. If the transaction flow is smaller than the minimum value of the preset flow limiting range, executing step S204; if the current transaction traffic is greater than the maximum value of the preset restriction range, step S206 is performed.
In the specific implementation process of step S203, if the current transaction traffic is not within the preset current limiting range, it is determined whether the current transaction traffic of the front-end system is less than the minimum value of the preset current limiting range. If the current transaction traffic of the front-end system is smaller than the minimum value of the preset current limiting range, executing step S204; if the current transaction traffic of the front-end system is greater than the maximum value of the preset current limit range, step S206 is performed.
It will be appreciated that if the current transacted transactional flow is not within the preset restriction, the current transacted transactional flow should be greater than the maximum value of the preset restriction or the current transacted transactional flow should be less than the minimum value of the preset restriction.
For example: the preset current limiting range is as follows: 100, 50, if the current transaction traffic is not within the preset restriction, the current transaction traffic should be greater than 100, or the current transaction traffic should be less than 50.
Step S204: and sending a processing request to the first target backward system.
In the process of specifically implementing step S204, if the current transaction traffic is within the preset current limit range, or if the current transaction traffic is less than the minimum value of the preset current limit range, a processing request is sent to the first target backward system.
It will be appreciated that the transaction request includes at least: a user identifier corresponding to the user initiating the transaction request, and a system name of each backward system involved in processing the transaction request. Based on the transaction request, a processing request is generated by using the user identification and the system name, and the processing request is sent to the first target backward system. The first target backward system is a backward system which communicates with the front-end system in each backward system involved in processing the transaction request.
Step S205: and receiving and displaying a processing result sent by the first target backward system based on the processing request.
In some embodiments, the first target backward system sends query information to the second target backward system after receiving the processing request. The query information is used for querying whether a user initiating the transaction request accords with preset transaction conditions.
It can be understood that after the second target backward system receives the query information, the query information is processed, whether the user initiating the transaction request accords with the preset transaction condition is queried, a query result is obtained, and the query result is fed back to the first target backward system.
For example, the preset transaction conditions are: the user initiating the transaction request is a bank credit card user, or the user initiating the transaction request is a bank guest card user, etc.
It should be noted that, after the first target backward system receives the query result sent by the second target backward system, the transaction request is processed based on the query result, so as to obtain a processing result.
It may be appreciated that the query result sent by the second target backward system may be: the user meets the preset transaction condition or the user does not meet the preset transaction condition.
If the query result indicates that the user accords with the preset transaction condition, the first target backward system processes the transaction request based on the query result to obtain a processing result; if the query result indicates that the user does not meet the preset transaction condition, the first target backward system processes the transaction request based on the query result to obtain an instruction: and the user does not meet the transaction condition, and the transaction fails to process the result.
In the process of specifically implementing step S205, the front-end system receives the processing result sent by the first target backward system based on the processing request, and displays the processing result.
Step S206: and feeding back transaction failure information to the user corresponding to the transaction request.
In the specific implementation process of step S206, if the current transaction flow is greater than the maximum value of the preset current limiting range, the front-end system feeds back the transaction failure information to the user corresponding to the transaction request. Wherein the transaction failure information comprises: busyness, inability to conduct transactions, etc.
In the embodiment of the invention, corresponding operation is carried out on the transaction request according to the relation between the current transactional flow of the front-end system and the preset flow limiting range, the normal operation of the system is protected, and the reasonable processing of the transaction request is ensured.
Referring to fig. 3 in combination with fig. 1 and fig. 2, a cross-system interaction timing diagram based on a coupon transaction according to an embodiment of the present invention is shown.
Step S301: the user clicks a get coupon button in the interactive page of the front-end system.
Step S302: the front-end system responds to the operation of the user to generate a transaction request, acquires the current transaction TPS based on the transaction request, and judges whether the current transaction TPS is within a preset current limiting range.
It should be noted that, if the current transaction TPS is greater than the maximum value of the preset current limiting range, displaying the system busy information on the interactive page of the front-end system; and if the current transaction TPS is within the preset current limiting range, sending a request for acquiring TPS and a processing request to the coupon system A.
Step S303: after receiving the TPS acquisition request and the processing request, the coupon system A sends query information to the bus query system B for querying whether the user accords with preset transaction conditions; and requests to acquire the TPS duty cycle value of bus inquiry system B.
It should be noted that, the TPS ratio of the bus inquiry system B is: the proportion of TPS of the bus inquiry system B in the maximum bearing value of the bus inquiry system B.
Step S304: the bus inquiry system B feeds back user information to the coupon system A based on the inquiry information; and simultaneously, the bus inquiry system B feeds back the TPS occupation ratio of the bus inquiry system B to the coupon system A.
Step S305: after receiving the user information, the coupon system A feeds back a processing result to the front-end system based on the user information and the processing request; meanwhile, the coupon system A feeds back the TPS occupation ratio of the coupon system A and the TPS occupation ratio of the bus inquiry system B to the front-end system.
It can be appreciated that the processing result is that the user successfully gets the coupon, or the user fails to meet the preset transaction condition, and the coupon is not successfully received.
It should be noted that, the TPS ratio of the coupon system a is: the TPS of the coupon system a accounts for the specific gravity of the maximum bearing value of the coupon system a.
Step S306: after receiving the TPS occupation ratio of the coupon system A and the TPS occupation ratio of the bus inquiry system B, the front-end system judges whether the TPS occupation ratio of the coupon system A and the TPS occupation ratio of the bus inquiry system B are smaller than preset values. And if the current limit ranges are smaller than the preset values, adjusting the preset current limit ranges. If the TPS occupation ratio of the coupon system A and/or the TPS occupation ratio of the bus inquiry system B is not smaller than the preset value, keeping the preset current limiting range unchanged.
Step S307: and after receiving the processing result, the front-end system displays the processing result on the interactive page.
In the embodiment of the invention, the current limiting set value is adjusted according to the relation between the TPS of the front-end system and the current limiting set value and the TPS duty ratio condition of the coupon system A and the bus inquiry system B in the process of processing the coupon service, so that the setting of the current limiting set value is more reasonable.
Referring to fig. 4 in conjunction with fig. 2, another interactive timing diagram across systems for coupon-based transactions is shown, provided by an embodiment of the present invention.
Step S401: the user clicks a get coupon button in the interactive page of the front-end system.
Step S402: the front-end system responds to the operation of the user to generate a transaction request, acquires the current transaction TPS based on the transaction request, and judges whether the current transaction TPS is within a preset current limiting range.
It should be noted that, if the current transaction TPS is smaller than the minimum value of the preset current limit range or the current transaction TPS is within the preset current limit range, the front-end system sends a processing request to the coupon system a; if the current transaction TPS is greater than the maximum value of the preset current limiting range, the front-end system displays the busy information of the system on the interactive page.
It will be appreciated that processing the request processes the transaction request for the request coupon system a.
Step S403: after receiving the processing request, the coupon system A sends query information to the bus query system B for querying whether the user accords with preset transaction conditions.
Step S404: the bus inquiry system B feeds back the user information to the coupon system A based on the inquiry information.
