[0035] In order to solve the above problems, a flow control method is provided in this embodiment, including but not limited to being applied to the Sentinel flow protection framework. Figure 2 is a flow chart of a flow control method according to an embodiment of the present application, the process includes the following steps S202-S204:

[0036] Step S202: Obtain N parameter values ​​from a parameter value set, wherein the parameter value set includes at least two of the following: the number of queries processed by the business unit in each time unit, the response time (ResponseTime, referred to as RT) of the business unit, the usage rate of the central processing unit (Central Processing Unit, referred to as CPU) of the target device running the business unit, the memory occupancy of the business unit, and the time node when the target device runs the business unit; N is an integer greater than or equal to 2;

[0037] It should be noted that the number of queries processed by a business unit in each time unit is the number of queries per second (QPS) of the business unit.

[0038] It should be noted that the business unit is used to run business services. To control the flow of a business unit is to control the flow of a business service.

[0039] Optionally, the business service is a microservice, which is a software architecture pattern that splits an application into small, independent, deployable services, each with its own business functions and data storage. These services collaborate with each other through lightweight communication mechanisms and can be deployed and expanded independently, thereby improving the maintainability, flexibility, and scalability of the system. The microservice architecture allows development teams to develop and deploy new features faster while reducing the complexity of the entire system. By splitting the application into small services, continuous integration and continuous deployment can be performed more easily, achieving the goal of rapid iteration and rapid response to customer needs.

[0040] Step S204: performing flow control on the service unit according to the N parameter values.

[0041] Optionally, the flow control includes: not limiting the flow of the business unit, limiting the flow of the business unit, fusing the business unit (ie, temporarily stopping access to the business unit), and downgrading the business unit.

[0042] The above steps control the flow of the service unit according to at least two parameters in the parameter value set, thereby solving the problem that the flow control framework cannot better control the flow of the service unit, and thus can better control the flow of the service unit.

[0043] In an exemplary embodiment, the above step S204 includes: step S11, or step S12, or step S11 and step S12, or step S11 and step S13, or step S12 and step S13, or step S11, step S12 and step S13:

[0044] Step S11: When the response time is greater than or equal to the first response time, flow control is performed on the service unit according to the CPU usage rate;

[0045] Optionally, the first response time is 1000ms.

[0046] Step S12: When the response time is greater than or equal to the second response time and less than the first response time, flow control is performed on the business unit according to the number of queries;

[0047] Optionally, the second response time is 20 ms.

[0048] Step S13: when the time response is less than the second response time, no flow limiting is performed on the service unit.

[0049] In an exemplary embodiment, the flow control of the service unit is performed according to the usage rate of the CPU, including the following steps S111-S112:

[0050] Step S111: when the CPU usage rate is less than the first usage rate, flow control is performed on the service unit according to the memory occupancy;

[0051] Optionally, the first usage rate is 90%.

[0052] Optionally, flow control is performed on the business unit according to the memory occupancy, including: when the memory occupancy is used to indicate that the size of the memory occupied by the business unit on the target device is greater than or equal to a first size, flow limiting is performed on the business unit; when the memory occupancy is used to indicate that the size of the memory occupied by the business unit on the target device is less than the first size, no flow limiting is performed on the business unit.

[0053] Optionally, the first size is 3G.

[0054] Step S112: When the CPU usage rate is greater than or equal to the first usage rate, flow control is performed on the service unit according to the time node.

[0055] Optionally, flow control is performed on the business unit according to the time node, including: when the time node is a stress test time node, no flow control is performed on the business unit; when the time node is not a stress test time node, flow control is performed on the business unit.

[0056] In an exemplary embodiment, performing flow control on the service unit according to the query times includes the following steps S121 and / or S122:

[0057] Step S121: When the query number is greater than or equal to the preset query number, flow control is performed on the service unit according to the time node;

[0058] Optionally, the preset query number is 20 times.

[0059] Step S122: when the query number is less than the preset query number, the service unit is not subject to flow restriction.

[0060] In an exemplary embodiment, performing flow control on the service unit according to the time node includes the following steps S21 and / or S22:

[0061] Step S21: when the time node is a stress test time node, not limiting the flow of the business unit;

[0062] It should be noted that since limiting the flow of a business unit will affect the stress test of the business unit, when the business unit is at a stress test time node, the flow limiting configuration is deleted in advance and the business unit is not limited.

[0063] Step S22: When the time node is not the stress test time node, flow control is performed on the business unit according to the CPU usage rate.

[0064] In an exemplary embodiment, the flow control of the service unit is performed according to the usage rate of the CPU, including the following steps S31-S32:

[0065] Step S31: when the time node is a preset time node, determining a preset usage rate corresponding to the preset time node;

[0066] Step S32: performing flow control on the service unit according to the relationship between the CPU usage rate and the preset usage rate.

[0067] Optionally, when the preset time node is an activity day node, determine a first preset usage rate corresponding to the activity day node; when the CPU usage rate is greater than or equal to the first preset usage rate, limit the flow of the business unit; when the CPU usage rate is less than the first preset usage rate, determine the memory usage of the business unit, and when the memory usage is used to indicate that the size of the memory occupied by the business unit on the target device is greater than or equal to a second size, limit the flow of the business unit; when the memory usage is used to indicate that the size of the memory occupied by the business unit on the target device is less than the second size, do not limit the flow of the business unit.

[0068] Optionally, the first preset usage rate is 99% and the second size is 4G.

[0069] Optionally, when the preset time node is an inactive day node, determine a second preset usage rate corresponding to the inactive day node; when the CPU usage rate is greater than or equal to the second preset usage rate, limit the flow of the business unit; when the CPU usage rate is less than the first preset usage rate, determine the memory usage of the business unit, and when the memory usage is used to indicate that the size of the memory occupied by the business unit on the target device is greater than or equal to a third size, limit the flow of the business unit; when the memory usage is used to indicate that the size of the memory occupied by the business unit on the target device is less than the second size, do not limit the flow of the business unit.

[0070] Optionally, the second preset usage rate is 80%, and the third size is 3G.

[0071] For a better understanding, the specific implementation of the above step S204 is described in detail. Figure 3 The flow control rules shown (in the form of a decision tree) are as follows: Figure 3 As shown in the figure, when the response time is abnormal, the flow protection will not be triggered directly, but the flow control will be carried out in combination with other rule nodes.

[0072] In an exemplary embodiment, before the above-mentioned step S202, the method further includes: in the case of monitoring that the traffic control rules are updated in the configuration center, obtaining the traffic control rules from the configuration center; wherein the traffic control rules are used to indicate obtaining the N parameter values ​​from the parameter value set, and performing traffic control on the business unit according to the N parameter values.

[0073] For better understanding, Figure 4 As shown in the figure, users can modify the flow control rules in the configuration center through the console, and then the Sentinel flow protection framework obtains and loads the flow control rules from the configuration center when it detects that the flow control rules have been updated in the configuration center. It should be noted that a rule engine can be added to the core code of Sentinel to execute the obtained flow control rules (i.e. Figure 3 Decision tree shown).

[0074] It should be noted that this application is based on the sentinel traffic protection framework for optimization and transformation to make the traffic protection function more secure and reliable, solve the problem that the triggering condition of the flow control rule is single and cannot be matched and associated with other reference items, and solves the problem of cumbersome and complicated configuration of the flow control rules. When there are exception scenarios similar to stress testing, there is no need to reconfigure the rules.

[0075] It should be noted that the traffic control method can be applied to network traffic control, server load control, API access control, database access control, software license control, and mobile communication traffic control. In general, the traffic control method is suitable for scenarios where it is necessary to manage and restrict the use of various traffic.

[0076] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods of each embodiment of the present application.
