Referring to FIG. 1, FIG. 1 is an implementation flowchart of a network node scheduling method shown in an exemplary embodiment of the present application. The execution subject of the network node scheduling method in this embodiment is an electronic device, and the electronic device may specifically be The server side that performs the management of all network nodes that perform service requests corresponding to microservices. The server side is used as an example for description. The scheduling method of network nodes as shown in FIG. 1 may include the following steps S110 to S130, which are described in detail as follows.

Step S110, in response to a service request initiated by the user terminal to execute the service corresponding to the microservice, obtain the current load, current performance, and current load of each network node used to execute the service corresponding to the microservice in the service request. distance.

In an embodiment of the present application, the user terminal sends a service request for requesting the execution of a service corresponding to the microservice to the server, where the service request may be a data query request, which is of course not limited to this. The service request is also It can be a request to perform other services. Specifically, the service request may be triggered by the user manually operating a physical button or virtual control provided by the terminal. It should be noted that the above service request carries geographic location information located by the user terminal.

The server responds to the service request of the service corresponding to the microservice initiated by the user terminal, and needs to determine the target for executing the service corresponding to the microservice in the service request from all network nodes that execute the service corresponding to the microservice in the service request Network nodes, where each network node corresponds to a network device used to execute the service corresponding to the microservice in the service request.

The server can directly obtain the current load of each network node and the current performance of each network node from the network equipment corresponding to each network node. When the server side determines the current distance between each network node and the user terminal, it can obtain the geographic location information of the network node from the network device corresponding to the network node, and based on the geographic location information of the network node and the service request carried The geographic location information located by the user terminal determines the current distance between the network node and the user terminal.

Step S120: Determine the priority of each network node in executing the microservice corresponding service in the service request based on the current load, current performance, and current distance from the user terminal of each network node.

In an embodiment of the present application, due to differences in the three dimensions of the current load, current performance, and current distance from the user terminal of each network node, the current load of the network node may be the current network device corresponding to the network node. The number of service requests processed, the more the number of service requests currently processed by the network device, the greater the current load of the network node. When the current load of the network node is smaller, the effect of the network node in executing the service request is better, and the more suitable it is to be the target network node for executing the service corresponding to the microservice in the service request, so the priority is higher. The current performance of the network node may be the current processor performance of the network device corresponding to the network node. The better the current processor performance of the network device corresponding to the network node, the better the current processor performance of the network device corresponding to the network node. The better the current performance of the network node, the better the effect of the network node in executing the service request, and the more suitable it is to be the target network node for executing the service corresponding to the microservice in the service request, so the priority is higher; The smaller the current distance between the node and the user terminal, the better the effect of the network node in executing the service request, and the more suitable it is as the target network node for executing the service corresponding to the microservice in the service request, so the priority is higher. The server determines the priority of each network node's microservice corresponding business in the execution of the service request based on the three dimensional information of each network node's current load, current performance, and current distance from the user terminal.

Step S130: Determine a target network node for executing the service corresponding to the microservice in the service request based on the priority of each network node in executing the service corresponding to the microservice in the service request.

In an embodiment of the present application, after determining the priority of each network node used to execute the service corresponding to the microservice in the service request, the server will determine the microservice used to execute the service request according to the priority. The target network node corresponding to the service.

Referring to FIG. 2, FIG. 2 is an implementation flowchart of a network node scheduling method shown in an exemplary embodiment of the present application. As shown in FIG. 2, the method is based on each network node in the execution of the service request. The priority of the service corresponding to the service determines the target network node for executing the microservice corresponding service in the service request. The step S130 includes: step S230, determining the network node with the highest priority as the target network node for executing the service request The microservice corresponds to the target network node of the business.

The server side may determine the network node with the highest priority as the target network node for executing the service corresponding to the microservice in the service request.

Optionally, the server side can also randomly select a network node from all network nodes with a priority higher than a set threshold as the target network node for executing the service corresponding to the microservice in the service request.

It can be seen from the above that the server determines the priority of each network node in the execution of the microservice corresponding service in the service request based on the current load, current performance of each network node and the current distance from the user terminal. The priority of the service corresponding to the microservice in the execution of the service request is determined to determine the target network node used to execute the service corresponding to the microservice in the service request, and then all network nodes that execute the service corresponding to the microservice in the service request are selected to execute the service request The network node with better performance at the time avoids selecting the network node with poor performance in processing service requests, thereby improving the efficiency of completing service requests.

Referring to FIG. 3, FIG. 3 is a specific implementation flowchart of step S230 in a network node scheduling method shown in an exemplary embodiment of the present application.

In an embodiment of the present application, before the server side determines the network node with the highest priority as the target network node for executing the service corresponding to the microservice in the service request, it may first obtain the highest priority from the preset log information database. All logs generated when the network node of the network node executes the service corresponding to the microservice in the service request in the current time and a specific time period before the current time. Among them, all logs of the network node with the highest priority during the current time and a specific time period before the current time may be all logs within one week before the current time, which is not limited here.

It is understandable that the preset log information database can be the log information database storing logs of the network device corresponding to the network node, and the log information in the log includes at least the network node with the highest priority when executing the service corresponding to the microservice in the service request. The above response status information is the information that the network node with the highest priority is responding successfully when executing the microservice corresponding service in the service request or the network node with the highest priority is executing the microservice corresponding service in the service request In addition, the log information may also include the reason why the network node with the highest priority did not respond when executing the service corresponding to the microservice in the service request.

Step S2302: Determine, based on the response status information in the log information, the response success rate of the microservice corresponding service in the service request executed by the network node with the highest priority in the current time and a specific time period before the current time.

In an embodiment of the present application, the server side obtains the response status information in the log information of all logs, and according to the response status information of all logs, the number of logs that respond successfully when executing the microservice corresponding business in the service request accounts for all The ratio of the number of logs determines the response success rate of the microservice corresponding service in the service request by the network node with the highest priority during the current time and the specific time period before the current time.

Step S2303, if the response success rate of the microservice corresponding service in the service request executed by the network node with the highest priority in the current time and a specific time period before the current time is higher than a predetermined threshold, the network node with the highest priority will be selected The network node is determined as a target network node for executing the service corresponding to the microservice in the service request.

In an embodiment of the present application, if the network node with the highest priority executes the microservice corresponding service in the service request within a specific time period before the current time and the response success rate of the service is higher than the predetermined threshold, it indicates that the network node The probability of failure when executing the service corresponding to the microservice in the service request is low, and the server can determine the network node with the highest priority as the target network node for executing the service corresponding to the microservice in the service request.

It should be pointed out that when the network node with the highest priority executes the microservice corresponding service in the service request within a certain period of time before the current time and the response success rate is lower than the predetermined threshold, the server can execute the service Other network nodes with a lower probability of failure and higher priority when the microservice in the request corresponds to the service are determined as the target network node for executing the service corresponding to the microservice in the service request.
