[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0026] Figure 1 This is the first flow chart of a flow control method provided in an embodiment of the present invention. The method in the embodiment of the present invention can provide a more flexible, more accurate and more fine-grained flow control mechanism, so that the business system can accurately limit the flow of different businesses and different interfaces, thereby improving the stability of the business system and further improving the user experience. The information collected in the method in the embodiment of the present invention is information and data authorized by the user or fully authorized by all parties, and the collection, storage, use, processing, transmission, provision, disclosure and application of the relevant data comply with the relevant laws, regulations and standards of the relevant countries and regions, take necessary confidentiality measures, do not violate public order and good morals, and provide corresponding operation entrances for users to choose to authorize or refuse. The method can be executed by a flow control device provided in an embodiment of the present invention, and the device can be implemented in software and / or hardware. The following embodiments will be described by taking the device integrated in an electronic device as an example. The electronic device can be a server or a computer device, etc., with reference to Figure 1 , the method may specifically include the following steps:

[0027] Step 101: Receive a service request sent by a user at the current moment.

[0028] Among them, a business request is a request sent by a user when interacting with a business system through a request interface when handling a business. For example, when a user uses the intelligent question-and-answer service of a business system, he sends a question to the business system. The business system can receive the question request sent by the user through the interface provided by the intelligent question-and-answer service. Specifically, by receiving the request sent by the user, the business system can interact with the user, understand the user's needs and provide instant feedback. The business system receives a large number of requests at all times. Limiting the flow of requests can ensure that all users can use system resources within a reasonable range, and prevent some users from occupying too many resources and affecting the experience of other users.

[0029] Step 102: Determine the target flow limiting rule of the business request according to the request interface of the business request, the preset flow limiting rules of each interface, and the preset flow limiting rules of each object.

[0030] Among them, the target flow limiting rules include target interface flow limiting rules and target object flow limiting rules. Business objects are specific entities that interact with the business system. Business objects can be enterprises, organizations, partners or individual users, etc. A business object can correspond to multiple request interfaces, and a request interface can be used by multiple business objects. Different business objects correspond to different object flow limiting rules. Object flow limiting rules include object unit time and object unit time total flow. The object unit time total flow is the total cumulative flow that all interfaces of the business object can use within the object unit time. The object unit time is a time interval predetermined by the business system based on the characteristics of domain big data and business objects. Different business objects correspond to different object unit times, and the object unit time can be one second, one minute or five minutes, etc. If the cumulative flow used by all interfaces of a business object within an object unit time exceeds the object unit time total flow specified in the flow limiting rules of the business object, it is necessary to limit the flow of the request interface of the business object within the object unit time.

[0031] Different request interfaces also correspond to different interface flow limiting rules. The interface flow limiting rules include the total interface flow per unit time of each interface and the total interface flow per unit time that can be provided for each business object. Different interfaces can correspond to different interface unit times, and the total interface flow per unit time is all the flow that the interface can provide per unit time. The flow that an interface can provide to different business objects per unit time can also be different. Exemplarily, the interface unit time of interface A is 5 minutes, there are 3 business objects, and the total interface flow per unit time of interface A is 10 megabytes. Interface A can be used by all objects, and the flow that can be provided to each business object per unit time is the total interface flow per unit time of the interface. It can be determined that within each 5 minutes, interface A can provide flow for all business objects, but the total accumulated flow cannot exceed 10 megabytes. Exemplarily, the interface unit time of interface A is 5 minutes, there are 3 business objects, and the total interface flow per unit time of interface A is 10 megabytes. Interface A can provide 8 megabytes of flow for business object 1, 1 megabyte of flow for business object 2, and 1 megabyte of flow for business object 3. If a service request 3 corresponding to a service object requests more than 1 megabyte of traffic within 5 minutes, the service request needs to be limited. Specifically, after receiving the service request sent by the user, the target interface limiting rule is determined according to the request interface used by the service request, and the target object limiting rule is determined according to the service object to which the service request belongs.

[0032] Step 103: Determine the available flow of the service request at the current time based on the request interface, the current time and the target flow limiting rule.

[0033] Among them, the target flow limiting rules include target interface flow limiting rules and target object flow limiting rules; the target object flow limiting rules include the object unit time of the business object and the total flow per object unit time. According to the target object flow limiting rules, the service available flow of the service request can be determined, and the object unit time available flow is the flow that can be used by the request interface within the object unit time at the current moment. According to the target interface flow limiting rules, the interface available flow of the service request can be determined. The interface available flow of the service request is the flow that the service request can still use on the request interface at the current moment. Specifically, after determining the service available flow of the service request and the interface available flow of the service request, the flow with the smaller flow value of the two flows can be determined as the available flow of the service request at the current moment. That is, if the interface available flow is greater than or equal to the service available flow, the service available flow is determined to be the available flow of the service request at the current moment; if the interface available flow is less than the service available flow, the interface available flow is determined to be the available flow of the service request at the current moment.

[0034] Exemplarily, business object 1 can use interface A and interface B. The flow limiting rule corresponding to business object 1 is: the total flow per minute does not exceed 30 megabytes. At 3 minutes and 00 seconds, it is determined that interface A uses 25 megabytes of flow, interface B uses 5 megabytes of flow, and at 3 minutes and 42 seconds, the service request sent by interface A is received, then the service available flow of the service request is determined to be: 30-25-5=0 megabytes. Interface A can provide 50 megabytes of flow for business object 1 every 10 minutes. At 1 minute and 00 seconds, interface A provides 25 megabytes of flow for business object 1, then the interface available flow of the service request corresponding to business object 1 is 25 megabytes. Further, according to the service available flow of the service request (0 megabytes) and the interface available flow of the service request (25 megabytes), it is determined that the available flow of the service request at the current moment is 0 megabytes.

[0035] Step 104: Limit the flow of the service request based on the request flow of the service request and the available flow at the current moment.

[0036] Among them, the request flow of the business request is the flow that the business system needs to use to respond to the business request. Specifically, after determining the business available flow of the business request, the business system calculates the request flow of the business request according to relevant parameters such as the complexity of the business request. The business request is limited according to the request flow and the available flow of the business request at the current moment. In this scheme, optionally, the business request is limited based on the request flow of the business request and the available flow at the current moment, including: if the request flow is greater than the available flow, the business importance level of the business request is obtained; if the business importance level belongs to the preset level, the business request is sent to a pre-established request queue; based on the request queue, the business request is responded to in the next unit time.

[0037] Among them, the business importance level is pre-defined by the business system according to the importance of different businesses. The higher the importance level of a business, the more important the business is. The preset level is pre-set by the business system and is used to determine the importance level of how to limit the flow of business requests. Specifically, when the business request flow exceeds the available flow at the current moment, it means that the business request needs to be limited. However, for some very important businesses, directly rejecting the request may lead to poor user experience. In this solution, when the business request flow exceeds the available flow at the current moment, the business importance level corresponding to the business request is determined. If the business importance level belongs to the preset level, it means that the importance of the business is high, and the business request can be temporarily stored in the request queue. For the business request placed in the queue, a confirmation message can be returned to the user to inform him that the business request has been accepted and will be processed later. If the business importance level does not belong to the preset level, the business request can be directly rejected. If the request flow is less than the available flow at the current moment, it does not need to be limited, and the business request can be directly responded to.

[0038] For example, suppose there is an e-commerce service (business object), in which interface A is used to process user requests such as shopping cart operations, order submission and payment. The business importance levels are: shopping cart operations: medium; order submission: high; payment: urgent. According to the target flow limiting rules, the e-commerce service can still use 5 megabytes of traffic through interface A at the current moment. At this time, a new order submission request is received, and its expected traffic is 6 megabytes. After receiving the request, the system determines that the request traffic is 6 megabytes, and after comparing it with the available traffic at the current moment (5 megabytes), it determines that it needs to be limited. Furthermore, the business system obtains that the business importance level of the business request is high and belongs to the preset level. The request is then placed in the pre-established request queue for processing.

[0039] Adopting different processing strategies for different business importance levels can improve user experience while ensuring system stability.

[0040] The technical solution of this embodiment receives a service request sent by a user at the current moment; determines the target flow limiting rule of the service request according to the request interface of the service request, the pre-set flow limiting rules of each interface and the pre-set flow limiting rules of each object; wherein the target flow limiting rule includes the unit time and the total flow per unit time; determines the available flow of the service request at the current moment based on the request interface, the current moment and the target flow limiting rule; and limits the flow of the service request based on the request flow of the service request and the available flow at the current moment. The technical solution of this embodiment limits the flow of different request interfaces according to different flow limiting rules based on unit time, can finely control the flow of the request interface, improve the accuracy and flexibility of the flow limiting, enable the business system to accurately limit the flow of different services and different interfaces, improve the stability of the business system, and further improve the user experience.

[0041] Figure 2 The second flow chart of a flow control method provided by an embodiment of the present invention is a refinement of the above embodiment. The specific method can be as follows Figure 2 As shown, the method may include the following steps:

[0042] Step 201: Receive a service request sent by a user at the current moment.

[0043] Step 202: Obtain the interface identifier of the request interface, and determine the target interface current limiting rule according to the interface identifier and the current limiting rules of each interface.

[0044] Among them, the interface identifier is used to mark different interfaces, and one interface identifier corresponds to one interface. Different request interfaces also correspond to different interface current limiting rules, and the interface current limiting rules include the total interface flow per unit time and the interface flow per unit time that can be provided for each business object. Different interfaces can correspond to different interface unit times. Specifically, after receiving the service request sent by the user, determine the interface identifier of the request interface through which the user sends the service request, determine the interface current limiting rule corresponding to the interface identifier in each predetermined interface current limiting rule, and determine it as the target interface current limiting rule.

[0045] Step 203: Determine the target business object to which the business request belongs, and determine the target object current limiting rule according to the current limiting rules of each object of the target business object.

[0046] Specifically, the flow limiting rules for each object are pre-defined by the business system according to the characteristics of different business objects. The object flow limiting rules include the object unit time and the total flow per object unit time. Different business objects correspond to different flow limiting rules. The total flow per object unit time of some business objects with higher business importance may be slightly larger, while the total flow per object unit time of some business objects with lower business importance may be slightly smaller. After receiving the business request, the target business object to which the business request belongs is determined according to the content of the business request. After determining the target business object, the flow limiting rule for the target business object is determined in each object flow limiting rule, and it is determined as the target object flow limiting rule corresponding to the business request.

[0047] Step 204: Calculate the service available flow of the service request based on the target object flow limiting rule.

[0048] Specifically, after determining the target object flow limiting rule, the object unit time at the current moment is determined according to the object unit time specified in the target object flow limiting rule. For example, if the unit time is per minute, the current moment needs to be converted into minutes. After determining the object unit time, the traffic used by the business object through all interfaces in the object unit time at the current moment is obtained. Exemplarily, the business object is an "order processing system", which includes two interfaces: interface 1 and interface 2. The unit time is 1 minute, and the current moment is 10:02:30. Assuming that the start time is 00:00, the object unit time at the current moment is determined to be the 21st minute. Interface 1 used 5 megabytes of traffic in the 21st minute, and interface 2 used 3 megabytes of traffic in the 21st minute. It is determined that the traffic usage of all interfaces of the target business object in the current object unit time is 8 megabytes. After obtaining the traffic usage of the current unit time, the difference between the traffic usage of the object unit time at the current moment and the total traffic of the object unit time of the target flow limiting rule can be determined as the service available traffic of the service request. Exemplarily, the traffic usage per unit time of all interfaces of the target business object at the current moment is 8 megabytes, and the total traffic per unit time of the object in the target flow limiting rule is 10 megabytes, then the business available traffic for the business request at the current moment is determined to be 2 megabytes.

[0049] Step 205: Determine the available flow of the service request at the current moment according to the target interface current limiting rule, the service request and the service available flow.

[0050] Among them, the interface current limiting rules include the total interface flow per unit time and the interface flow per unit time that can be provided to each business object. Specifically, after determining the service available flow of the business request, determine how much flow (interface available flow) the business request can still use through the request interface according to the target interface current limiting rules, and determine the available flow of the business request at the current moment according to the interface available flow and the service available flow. In this scheme, optionally, the available flow of the business request at the current moment is determined according to the target interface current limiting rules, the business request and the service available flow, including: calculating the interface available flow of the business request based on the target interface current limiting rules; if the interface available flow is greater than or equal to the service available flow, determining the service available flow as the available flow of the business request at the current moment; if the interface available flow is less than the service available flow, determining the interface available flow as the available flow of the business request at the current moment.

[0051] Specifically, after determining the target interface current limiting rule, obtain the used traffic used by the business object on the request interface (target interface) within the interface unit time at the current moment, and determine the difference between the total interface unit time traffic of the business request fixed in the target interface current limiting rule and the used traffic as the interface available traffic of the business request on the request interface at the current moment. Compare the interface available traffic with the available business traffic. If the interface available traffic is greater than or equal to the business available traffic, determine the business available traffic as the available traffic of the business request at the current moment; if the interface available traffic is less than the business available traffic, determine the interface available traffic as the available traffic of the business request at the current moment.

[0052] Step 206: Limit the flow of the service request based on the request flow of the service request and the available flow at the current moment.

[0053] In the technical solution of this embodiment, a service request sent by a user at the current moment is received. The interface identifier of the request interface is obtained, and the target interface current limiting rule is determined according to the interface identifier. The target business object to which the service request belongs is determined, and the target object current limiting rule is determined according to the target business object. The service available flow of the service request is calculated based on the target object current limiting rule. The available flow of the service request at the current moment is determined according to the target interface current limiting rule, the service request, and the service available flow. The service request is current limited based on the request flow of the service request and the available flow at the current moment. The technical solution of this embodiment can accurately determine the interface current limiting rule according to the interface identifier, and determine the object current limiting rule according to the service request, so as to perform multi-dimensional current limiting on the service request according to the interface current limiting rule and the object current limiting rule corresponding to the service request, thereby realizing refined control of the flow of the request interface, improving the accuracy and flexibility of current limiting, enabling the service system to accurately limit the flow of different services and different interfaces, improving the stability of the service system, and further improving the user experience.

[0054] Figure 3 Flow chart of a method for adjusting the flow limiting rules of each business object provided by an embodiment of the present invention. The specific method can be as follows Figure 3 As shown, the method may include the following steps:

[0055] Step 301: Obtain the traffic usage of each business object according to the preset time interval corresponding to each business object.

[0056] Among them, the traffic usage includes the number of flow restrictions and the traffic usage information of each object per unit time within the preset time interval. The preset time interval is determined by the business system based on the domain big data and the specific application environment. The preset time interval is used to instruct the business system to regularly collect and analyze traffic usage. The business system can collect the traffic usage data of all business objects in each time interval according to the preset time interval. The traffic usage data of each object per unit time of each business object in the time interval is counted to obtain the traffic usage information of each business object at each point time. For example, the preset time interval is one week, and the unit time of each object includes 1 minute, 30 minutes, 1 hour and 1 day. Then the business system can count the number of flow restrictions and traffic usage corresponding to the business object every 1 minute, 30 minutes, 1 hour and 1 day in each week.

[0057] Step 302: For each business object, analyze the traffic usage of the current business object to obtain an analysis result, and adjust the object flow limiting rule of the current business object based on the analysis result.

[0058] Specifically, after obtaining the traffic usage of each business object, the business system can perform a detailed analysis of the traffic usage of each business object to obtain the analysis results. The analysis results include the average traffic, peak traffic, and current limiting triggering frequency of the business object. Based on the analysis results, the business system can determine the characteristics of each business object, such as which business objects consume more traffic and which business objects frequently trigger current limiting, so as to adjust the current limiting rules of the business objects according to the characteristics of the business objects. For example, if a business object frequently triggers current limiting, the total traffic limit per unit time of the object can be appropriately increased; conversely, if a business object rarely triggers current limiting, the total traffic limit per unit time of the object can be appropriately reduced.

[0059] The technical solution of this embodiment obtains the traffic usage of each business object according to the preset time interval corresponding to each business object; wherein the traffic usage includes the number of flow limiting times and the traffic usage information of each unit time within the preset time interval; for each business object, the traffic usage of the current business object is analyzed to obtain the analysis result; based on the analysis result, the flow limiting rules of the current business object are adjusted. The technical solution of this embodiment can effectively manage and optimize the traffic usage of each business object. It not only helps to ensure the stability and performance of the system, but also improves the utilization rate of resources. By dynamically adjusting the flow limiting rules, it can better adapt to the changing business needs and ensure the smooth operation of key businesses.
