[00751 The above scenario includes information acquisition and real-time data Date Regue/Date Received 2023-02-21 computation.
[0076] The information acquisition includes as below:
[0077] Acquisition 1: when the service system accesses the data system, the gateway layer interface records the name of the current service system, the interface address of the request, the trigger time of the request, the request content and so on (note: the recorded information stored on the gateway server at the moment); when the application server returns the final data to the gateway, the gateway records the end time of the request, the name of the depended system, the status of the request result and so on, then all the recorded infoimation is pushed on the information acquisition storage area.
[0078] Acquisition 2 : when receiving the request, the application server records the requesting user, the body information (the report information by requesting through the report, the indicator information by requesting through the indicators...), whether depending on the data support system, the name of the dependent data support system, the queue time for storing the request onto the data support system, the executing time of the data support system; when the data support system returns the data to the application server, the application server records the end time for the request and the status of the request, then all the recorded infoimation is pushed on the information acquisition storage area.
[0079] Acquisition 3 The data support system pushed current status information to the information acquisition storage area of the data monitoring platform.
[0080] The real-time data computation includes as below:
[0081] The data source is obtained from the information acquisition.
Date Regue/Date Received 2023-02-21 [0082] 1. Calculating the response time of each acquisition in real time, for example, the overall response time of each interface in the Acquisition L (the end time ¨ the trigger time), the queue time in the data support system in the Acquisition 2 (the executed time ¨ the queue time for storing in the data support system), the response time executed by the data support system (the end time ¨ the executed time).
[0083] 2. Calculating the overall service request quantity at the current window in the data system by the time window (30s or 60s), the average response time of each URL, the average response time of each data support system, the status of the data support system (if the current window fails to receive the feedback from the data support system, the status maintains the previous one, if the current window fails to receive the feedback for a while, the status is set to be unavailable.
[0084] 3. According to the calculation results above and the configuration information by the operation and maintenance personnel, adjusting the interface concurrency quantity for the entire interface and/or each interface.
[0085] Wherein the configuration infoimation rule includes as below:
[0086] 1. The interface concurrency quantity for the gateway layer interface is 500, in parallel, the interface concurrency quantity for the application layer interface on the data support system is 400.
[0087] 2. When the average response time of the interface on the data system >5s, the interface concurrency quantity for the gateway layer is 50; the average response time >ls, the interface concurrency quantity for the gateway layer is 200; the average response time <1s, the interface concurrency quantity for the gateway layer is 500.
[0088] 3. When the executed response time of the interface or the waiting time on the Date Regue/Date Received 2023-02-21 data support system >5s, the interface concurrency quantity for the application layer is 50; the executed response time of the interface or the waiting time on the data support system >ls, the interface concurrency quantity for the application layer is 200; the executed response time of the interface or the waiting time on the data support system <1s, the interface concurrency quantity for the application layer is 500.
[0089] 4. When the status of the data support system is unavailable, the interface concurrency quantity for the application layer is 0. When the status of the data support system is sub-healthy, the interface concurrency quantity for the application layer is 200. When the status of the data support system is healthy, the interface concurrency quantity for the application layer is 500.
[0090] In the above scenario, according to the calculation results, the interface concurrency quantity is adjusted in real time. For example, the status of the data support system E, F are healthy, the average response time <1s. The service system concurrency quantity is greater than 500, the gateway layer proceeds the first 500 pieces of the requests, performs the circuit-breaking process for other requests, and prompts "the system is busy, try again later" for other requests; the subsequent requests depend on the connection number of the gateway.
[0091] When the status of the data support system E is sub-healthy, or the executed response time or waiting time >1 s, the interface concurrency quantity for the application layer on the data support system E decreased from 500 to 200; when the service system 500 send concurrently requests, if these requests are not involved in any data support system, then the requests are processed. If these requests are not involved in the data support system E, then the requests are processed. If these requests are involved in the data support system E and the quantity is less than 200, then the requests are processed.
If these requests involve in the data support system E and the quantity is greater than 500, the gateway layer does not intercept, but the application layer intercepts, which means that the application layer processes 200 of 500 requests only and performs Date Regue/Date Received 2023-02-21 circuit-breaking process for the rest of 500 requests.
[0092] If the data support system F has not pushed the status for a continuous period of time, the interface concurrency quantity for the application layer on the data support system F decreased from 500 to 0. The application layer refuses any requests relating to the data support system F.
[0093] For the implementation scenario, as an example of the report system for illustration. Wherein the upstream of the report system is the indicator service system, the system architecture is shown in Figure 5, the detailed process operation diagram is shown in Figure 6.
[0094] Step 1: the reporting system operates initial rules, within 1 minute, shown as below:
[0095] 1. If the average response time of the reports <100ms, the maximum connection number for controlling the service requests is 600;
[0096] 2. If the average response time of the reports <500ms, the maximum connection number for controlling the service requests is 400;
[0097] 3. If the average response time of the reports <1s, the maximum connection number for controlling the service requests is 200;
[0098] 4. If the average response time of the reports >=1s, the maximum connection number for controlling the service requests is 100, at the same time, circuit-breaking mode starts for part of the reports;
[0099] Step 2: data acquisitions for the service requests, calculating the acquired data at the frequency of one minute, calculating the average response time at the current one Date Regue/Date Received 2023-02-21 minute, and reporting TOPN sorted by a descending order within the average response time.
[0100] Result 1: the average response time of the service request at the current period is 50ms, the maximum connection number remains constant.
[0101] Result 2: the average response time of the service request at the current period is 200ms/800ms, the dynamic maximum connection number is adjusted from 600ms to 400ms/200ms.
[0102] Result 3: the average response time of the service request at the current period is 1100ms, the dynamic maximum connection number is adjusted from 600ms to 100ms, at the same time, the report TOPN is executed the circuit-breaking process.
[0103] The above-mentioned interface dynamic flow control method resolves the existing technical problems below:
[0104] 1. Current peak-clipping solutions regarding network flow control cannot perform autonomous optimal adjustment according to the system service pressure. The present application includes two types of autonomous optimal adjustments.
[0105] One is to analyze the historical data, and to acquire the optimal ratio of the system pressure and the threshold value of the peak-clipping for dynamically adjusting the initial rules.
[0106] Another one is to analyze and calculate the system pressure at the current period of time according to the acquired data, for example, the connection number, the average response time, then adjusting dynamically the threshold value of the peak-clipping according to the layered rules.

Date Regue/Date Received 2023-02-21 [0107] 2.
