All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present disclosure.
In the prior art, in order to limit the current transaction data, the current transaction is limited in a unified current limiting association mode, but the problems of resource waste, poor current limiting effect and the like exist when the current transaction is actually limited, so that the current transaction is insufficient to achieve the purpose of fully utilizing cluster resources.
Based on this, the embodiment of the specification provides a transaction current limiting method, by adopting the embodiment of the specification, analyzing task data and equipment proportion, calculating the task data in a cluster angle, and obtaining single-machine current limiting data corresponding to each transaction type of each service equipment in a service equipment cluster corresponding to the cluster current limiting data according to the equipment proportion, thereby realizing adjustment of the current limiting data, so that the current limiting data of the service equipment cluster can meet the requirement of the task data by controlling the current limiting data output by the service equipment, realizing dynamic adjustment of the current limiting data, and further realizing uniform and stable current limiting under self-adaptive control of multiple scenes.
Referring to fig. 1, a system architecture diagram of transaction flow limiting is provided for an embodiment of the present disclosure. As shown in fig. 1, the transaction flow restriction method provided in the embodiment of the present disclosure may be applied to a service device to implement a transaction flow restriction process for adjusting flow restriction data, and the system structure provided in the embodiment of the present disclosure mainly includes a service device 10 and a transaction device 20. The service device 10 may be one of large cluster servers used by an enterprise; the transaction device 20 may be a large-scale integrated server used by an enterprise, or may be a micro-computer, such as a personal computer.
In this embodiment of the present disclosure, the service device 10 obtains task data sent by the transaction device 20 at a first time, obtains a device proportion in a working state in a service device cluster where the service device 10 is located, obtains cluster task data and cluster adjustment data corresponding to a transaction type based on the task data and the device proportion, obtains first cluster current limiting data based on a preset deviation proportion and the cluster adjustment data, obtains cluster history data, obtains second cluster current limiting data based on the cluster history data and the cluster task data, and obtains stand-alone current limiting data corresponding to the transaction type based on the first cluster current limiting data, the second cluster current limiting data and the device proportion.

Based on the system architecture shown in fig. 1, the transaction flow limiting method provided in the embodiment of the present disclosure will be described in detail below with reference to fig. 2 to 4.
Referring to fig. 2, a flow chart of a transaction flow limiting method is provided in an embodiment of the present disclosure. As shown in fig. 2, the method may include the following steps S102 to S110.
S102, task data aiming at a service equipment cluster at a first moment and equipment proportion of service equipment in a working state in the service equipment cluster are obtained;
in one embodiment, each service device in the service device cluster obtains task data for the service device cluster at a first time, and obtains a device proportion of the service devices in the service device cluster that are in an operational state at the first time.
The service device cluster may be a service device cluster for sending the transaction data to the transaction partner, and the service device cluster may include at least one service device, and the transaction data is sent to the transaction partner according to each service device.
The first time may be the current time when the service device receives the task data, for example, when the service device receives the task data at the time of 12:00, the time of "12:00" is taken as the current time when the service device receives the task data, that is, the first time.
The task data may include specific task information that needs to be executed by the terminal device cluster.
The device proportion may be the proportion of service devices capable of working and in a working state in the service device cluster to the service device cluster, for example, 10 machines exist in the service device cluster, and the proportion of service devices capable of working and in a working state is 10, and the device proportion is 1:10. For example, as shown in fig. 3, 9 service devices exist in the service device cluster in fig. 3, and if the 9 service devices are all in a working state, the device ratio is 1:9.
In the embodiment of the present disclosure, any service device is selected as an object of description to describe when each service device in the service device cluster obtains task data, and the data processing process of other service devices may refer to the data processing method of the service device.
S104, acquiring cluster task data from the task data based on the transaction type, and acquiring cluster adjustment data based on the task data and the equipment proportion;
in one embodiment, after task data is acquired, the task data is parsed, a transaction type and current cluster current limit data in the task data are acquired, cluster task data are acquired in the task data based on the transaction type, and cluster adjustment data are acquired based on equipment proportion and the current cluster current limit data.
It can be understood that in order to ensure the processing efficiency of the transaction, more than one task often exists in the task data, so that the task data is analyzed to obtain the transaction types of each task, and the cluster task data corresponding to the transaction types is obtained from the task data. It should be noted that, because the cluster task data corresponding to different task types are not mutually interfered when performing calculation and execution, for convenience of explanation, in the embodiment of the present disclosure, any one of the task types is described, and other task types are not described in detail.
The current cluster current limiting data may be current limiting data output by a service device cluster of a terminal device at a time adjacent to a previous time of the first time, so as to adjust the current limiting data of the first time according to the current cluster current limiting data. It can be understood that the current cluster current-limiting data can be data carried in the task data, or can be data obtained by searching in a database of the service equipment cluster or a storage unit of the service equipment according to the task identifier in the task data.
Furthermore, the cluster task data can be the data quantity which can be accepted and is set by the transaction partner according to the actual condition of the system of the transaction partner. It should be noted that the size of the cluster task data may also be different for different transaction types. For example, a transaction partner can accept 100 transactions per minute for cluster task data of transaction type A and 200 transactions per minute for cluster task data of transaction type B. For example, as shown in fig. 4, the task data after the task data is parsed is shown in fig. 4, and specifically includes 100 tasks per minute for the task data with a transaction type a, 200 tasks per minute for the task data with a transaction type B, and so on.
Optionally, one possible method for obtaining cluster adjustment data may be to obtain current single machine current limiting data based on the current limiting data and the device proportion, obtain single machine deviation data at the first moment, perform difference calculation based on the single machine deviation data and the current single machine current limiting data, obtain single machine adjustment data, and obtain cluster adjustment data corresponding to the single machine adjustment data based on the device proportion.
Alternatively, a possible single machine adjustment data calculation method may be to subtract single machine deviation data from current single machine current limit data to obtain single machine adjustment data. For example, when the current single machine current limit data is 5 and the single machine deviation data is 2.1, the single machine adjustment data is 2.9 (5-2.1), i.e. compared with the current single machine current limit data, the current limit data of the service equipment needs to be adjusted downwards by 2.9; if the current single machine current limit data is-1 and the single machine deviation data is-1.2, the single machine adjustment data is 0.2 (-1- (-1.2)), i.e. compared with the current single machine current limit data, the current limit data of the service equipment needs to be adjusted down by 0.2.
After the single machine adjustment data is obtained, cluster adjustment data is obtained based on the single machine adjustment data and the equipment proportion, for example, the single machine current limit data is 2.9, the equipment proportion is 1:10, and the cluster current limit data is 29 (2.9x10).
S106, calculating the cluster adjustment data by adopting a preset deviation ratio to obtain first cluster current limiting data;
in one embodiment, a preset deviation ratio is obtained, and the deviation ratio is used to calculate the cluster adjustment data, so as to obtain first cluster current limiting data.
Optionally, one possible method for calculating the first cluster current limit data may be to multiply the cluster adjustment data and the deviation ratio to obtain the first cluster current limit data.
The deviation ratio may be a preset value, and the deviation ratio may be a value for adjusting the change amplitude of the cluster adjustment data. For example, if the deviation ratio is 0.5 and the cluster adjustment data is 29, the first cluster current limit data is 14.5 (29×0.5).
S108, acquiring cluster historical data of historical time length, and acquiring second cluster current limiting data based on the cluster historical data and the cluster task data;
in one embodiment, cluster history data of a history duration is obtained, and second cluster current limit data is obtained after calculation is performed based on the cluster history data and the cluster task data.
The historical time length is adjacent time length before the first time, and cluster historical data of the service equipment in the historical time length are obtained from a database of the service equipment cluster or a storage unit of the service equipment. For example, the historical time period may be an adjacent time period of 5 minutes before the current time, and if the first time is 12:00, the historical time period includes 11:55, 11:56, 11:57, 11:58, and 11:59.
After the cluster historical data is obtained, cluster time period time of each adjacent time period in the cluster historical data is obtained, and each cluster time period data and cluster task data are respectively calculated to obtain a cluster deviation average value; and respectively calculating cluster time period data of each adjacent time period to obtain a cluster change rate value, and adding the cluster deviation mean value and the cluster change mean value to obtain second cluster current limiting data.
Optionally, in one possible cluster deviation average value calculating method, difference value calculation is performed on the data of each cluster period and the cluster task data to obtain first difference values, and average values are obtained after summation is performed on the first difference values to obtain a cluster deviation average value.
Optionally, one possible cluster change rate value calculating method may be to calculate a difference value of cluster time periods of each adjacent time period to obtain a second difference value, and sum up each second search and then obtain an average value to obtain a cluster change rate value.
S110, determining single machine current limiting data corresponding to the transaction type based on the first cluster current limiting data, the second cluster current limiting data and the equipment proportion;
in one embodiment, after the first cluster current limiting data, the second cluster current limiting data and the equipment proportion are obtained, summing the first cluster current limiting data and the second cluster current limiting data to obtain target cluster current limiting data, and calculating the target cluster current limiting data based on the equipment proportion to obtain single machine current limiting data corresponding to the transaction type.
When the target cluster current limiting data can be the first moment, the service equipment cluster determines the data to be adjusted after acquiring the task data aiming at the service equipment cluster. It can be understood that, because the target cluster current limit data is obtained by calculation, and each service device in the service device cluster is calculated and actually executed, the current single-machine current limit data and the current single-machine current limit data of the service device are needed to be distributed according to the device proportion, and then the actual output current limit data when the service device executes the task data is obtained, and the service device executes the task data by adopting the actual output current limit data.
The single machine current limit data can be data which is used by the service equipment for determining that the current single machine current limit data is required to be adjusted according to the transaction type.
It should be noted that, the service device includes a trained transaction current limiting model, where the transaction current limiting model may be an algorithm model for calculating single machine current limiting data, and the execution process in the embodiment of the present disclosure is a specific execution process in which the service device adopts the transaction current limiting model, inputs the obtained task data and the device proportion to the transaction current limiting model, and finally outputs the single machine current limiting data in combination with the cluster history data.
Optionally, a feasible training method of the transaction current limiting model may be that sample task data, sample equipment proportion and sample single machine current limiting data are obtained, the transaction current limiting model is trained based on the sample task data, the sample equipment proportion and the sample single machine current limiting data, and various parameters corresponding to the transaction current limiting model are obtained, so that training of the transaction current limiting model is completed.
Furthermore, another possible training method of the transaction current limiting model may be to input the obtained sample task data, the sample equipment proportion and the sample single machine current limiting data into the initialized transaction current limiting model, and improve the output rate of the single machine current limiting data output by the transaction current limiting model and the sample motor current limiting data which are the same or have the difference larger than a preset threshold value through adjusting the deviation proportion. And when the output rate reaches a preset output rate range, the transaction current limiting model is considered to be trained. It can be appreciated that when the deviation ratio is larger, the cluster current limiting data will also increase, so the adjustment amplitude will also increase accordingly, thereby affecting the output efficiency.
In the embodiment of the specification, task data and equipment proportion are acquired, then the task data is analyzed, calculation is performed in a cluster angle, and single-machine current limiting data corresponding to each transaction type of each service equipment in a service equipment cluster corresponding to the cluster current limiting data is obtained according to the equipment proportion, so that adjustment of the current limiting data is realized, the current limiting data of the service equipment cluster can meet the requirement of the task data by controlling the current limiting data output by the service equipment, dynamic adjustment of the current limiting data is realized, and unified and stable current limiting under multiple scenes is controlled in a self-adaptive mode.
Referring to fig. 5, a flow chart of a transaction flow limiting method is provided in an embodiment of the present disclosure. As shown in fig. 5, the method may include the following steps S202 to S232.
S202, task data aiming at a service equipment cluster at a first moment and equipment proportion of service equipment in a working state in the service equipment cluster are obtained;
in one embodiment, each service device in the service device cluster obtains task data for the service device cluster at a first time, and obtains a device proportion of the service devices in the service device cluster that are in an operational state at the first time.
The service device cluster may be a service device cluster for sending the transaction data to the transaction partner, and the service device cluster may include at least one service device, and the transaction data is sent to the transaction partner according to each service device.
The first time may be the current time when the service device receives the task data, for example, when the service device receives the task data at the time of 12:00, the time of "12:00" is taken as the current time when the service device receives the task data, that is, the first time.
The task data may include specific task information that needs to be executed by the terminal device cluster.
The device proportion may be the proportion of service devices capable of working and in a working state in the service device cluster to the service device cluster, for example, 10 machines exist in the service device cluster, and the proportion of service devices capable of working and in a working state is 10, and the device proportion is 1:10. For example, as shown in fig. 3, 9 service devices exist in the service device cluster in fig. 3, and if the 9 service devices are all in a working state, the device ratio is 1:9.
In the embodiment of the present disclosure, any service device is selected as an object of description to describe when each service device in the service device cluster obtains task data, and the data processing process of other service devices may refer to the data processing method of the service device.
S204, analyzing the task data to obtain the transaction type corresponding to the task data and current cluster current-limiting data;
in one embodiment, in order to ensure the processing efficiency of the transaction, more than one task often exists in the task data, so that the task data is parsed to obtain the transaction types of each task. It should be noted that, because the cluster task data corresponding to different task types are not mutually interfered when performing calculation and execution, for convenience of explanation, in the embodiment of the present disclosure, any one of the task types is described, and other task types are not described in detail.
The current cluster current-limiting data may be current-limiting data output by a service device cluster corresponding to a transaction type of a terminal device adjacent to a last time at the first time, so as to adjust the current-limiting data at the first time according to the current cluster current-limiting data. It can be understood that the current cluster current-limiting data can be data carried in the task data, or can be data obtained by searching in a database of the service equipment cluster or a storage unit of the service equipment according to the task identifier in the task data.
S206, acquiring cluster task data from the task data based on the transaction type;
in one embodiment, after the transaction type in the task data is acquired, searching is performed in the task data based on the transaction type, and cluster task data corresponding to the transaction type in the task data is acquired.
The cluster task data can be the data quantity which can be accepted and is set by the transaction partner according to the actual condition of the system. It should be noted that the size of the cluster task data may also be different for different transaction types. For example, a transaction partner can accept 100 transactions per minute for cluster task data of transaction type A and 200 transactions per minute for cluster task data of transaction type B. For example, as shown in fig. 4, the task data after the task data is parsed is shown in fig. 4, and specifically includes 100 tasks per minute for the task data with a transaction type a, 200 tasks per minute for the task data with a transaction type B, and so on. S208, current single machine current limiting data is obtained based on the current cluster current limiting data and the equipment proportion;
in one embodiment, based on the obtained current cluster current limit data and the device proportion, the current single machine current limit data is obtained through calculation between the current cluster current limit data and the device proportion.
For example, the current cluster current limit data is 110, the device ratio is 1:10, and the current single machine current limit data is 11 (110×0.1).
The stand-alone current limit data may be current limit data corresponding to a transaction type output by the service device at a time immediately preceding the first time.

in one embodiment, single machine deviation data at a first moment is obtained, and difference value calculation is performed based on the single machine deviation data and the single machine current limiting data obtained through calculation, so that single machine adjustment data of the service equipment at the first moment is obtained.
Alternatively, a possible single machine adjustment data calculation method may be to subtract single machine deviation data from current single machine current limit data to obtain single machine adjustment data. For example, when the current single machine current limit data is 11 and the single machine deviation data is 2.1, the single machine adjustment data is 8.9 (11-2.1)), i.e. compared with the current single machine current limit data, the current limit data of the service equipment needs to be adjusted down by 8.9; if the current single machine current limit data is-1 and the single machine deviation data is-1.2, the single machine adjustment data is 0.2 (-1- (-1.2)), i.e. compared with the current single machine current limit data, the current limit data of the service equipment needs to be adjusted down by 0.2.
S212, acquiring cluster adjustment data based on the single machine adjustment data and the equipment proportion;
in one embodiment, the cluster current limit data may be data obtained by performing calculation based on the stand-alone adjustment data and the device proportion, and the obtained data is primarily used for adjusting the cluster current limit data.
S214, calculating the cluster adjustment data by adopting a preset deviation ratio to obtain first cluster current limiting data;
in one embodiment, a preset deviation ratio is obtained, and the deviation ratio is used to calculate the cluster adjustment data, so as to obtain first cluster current limiting data.
Optionally, one possible method for calculating the first cluster current limit data may be to multiply the cluster adjustment data and the deviation ratio to obtain the first cluster current limit data.
The deviation ratio may be a preset value, and the deviation ratio may be a value for adjusting the change amplitude of the cluster adjustment data. For example, if the deviation ratio is 0.5 and the cluster adjustment data is 29, the first cluster current limit data is 14.5 (29×0.5).
S216, cluster history data of history duration is obtained;
in one embodiment, cluster history data of the service device within a history duration is obtained from a database of the service device cluster or a storage unit of the service device itself.
Further, the historical time period may be an adjacent time period before the first time, and the specific value of the historical time period may be set according to actual needs, for example, the historical time period may be an adjacent time period 5 minutes before the current time, and each time interval is 1 minute, and if the first time period is 12:00, the historical time period includes 11:55, 11:56, 11:57, 11:58, and 11:59.
It should be noted that, the cluster history data may be cluster current-limiting data of each history period in the history duration, where the cluster history data may be stored in a database of the service device cluster or a storage unit of the service device itself, or may be set by a user in a storage device set by itself, and may specifically be set according to actual needs.
S218, acquiring cluster time period data of each adjacent time period in the cluster historical data, and respectively calculating each cluster time period data and the cluster task data to obtain a cluster deviation average value;
in one embodiment, cluster time period time of each adjacent time period in cluster historical data is obtained, difference value calculation is carried out on each cluster time period data and cluster task data to obtain first difference values of each adjacent time period, and average value is obtained after summation is carried out on each first difference value to obtain cluster deviation average value.
For example, if the cluster task data is 100 and each cluster period data is 132, 120, 105, 97 and 102, respectively, the difference between each cluster period data and the cluster task data is calculated to obtain each first difference value which is 32, 20, 5, -3 and 2, respectively, and the first difference values are summed and then averaged to obtain the cluster deviation average value 11.2.

The second time is the next time adjacent to the first time, for example, the first time is 12:00, and the interval duration between each adjacent time is one minute, then the second time is 12:01. The interval time between each adjacent time can be set according to the actual situation.
It should be noted that, the service device includes a trained transaction current limiting model, where the transaction current limiting model may be an algorithm model for calculating single machine current limiting data, and the execution process in the embodiment of the present disclosure is a specific execution process in which the service device adopts the transaction current limiting model, inputs the obtained task data and the device proportion to the transaction current limiting model, and finally outputs the single machine current limiting data in combination with the cluster history data.
