For example, the user may be allowed to adjust the candidate policy configuration displayed on the display interface 103, and feed back the adjusted policy configuration to the control device 102, and the control device 102 may further use the adjusted policy configuration as a user confirmation result to obtain the target policy configuration. Then, the control device 102 may also issue the target policy configuration to the network device for network management.

Please refer to fig. 3, which illustrates a flowchart of a method for obtaining a candidate policy configuration according to an embodiment of the present application. As shown in fig. 3, the control device obtains candidate policy configurations of the network device, including but not limited to the following steps 1011 to 1013.

1011. First KPI data of a network device is obtained.

Optionally, the process of acquiring, by the control device, the first KPI data of the network device includes, but is not limited to, the control device receiving KPI data reported by the network device, aggregating the received KPI data, and processing the aggregated KPI data to obtain processed KPI data. The control device may then store the processed KPI data, and collect first KPI data of the network device from the stored KPI data. In a possible implementation manner, the control device may receive KPI data that is continuously collected by the network device from the existing network and actively reported to the control device, and the control device may also actively collect KPI data that is uploaded by the network device and receive KPI data from the network device. In addition, the KPI data sent by the network device to the control device may also be encrypted, and then, after the control device aggregates the received KPI data, the received KPI data is decrypted and converted to obtain the aggregated KPI data. Optionally, the control device processes the KPI data after aggregation, including but not limited to data cleansing and processing of null and outliers. Optionally, the control device may further fuse and classify the processed KPI data based on definition information, which includes but is not limited to definitions of storage granularity, category, and duration of the data, to obtain the processed KPI.

The method for storing the processed KPI data by the control device is not limited in the embodiment of the present application, for example, the control device may store the processed KPI data to the storage device, where the storage device may be directly deployed in the control device, or the control device and the storage device may be respectively deployed on different devices, and then communicate through a network. Furthermore, the control device may store the processed KPI data in different formats in a database corresponding to the storage device. Since the processed KPI data contains multiple types of data, it needs to be stored in different formats in the database corresponding to the storage device. Optionally, the control device periodically collects first KPI data of the network device from KPI data stored in the storage device.

The first KPI data of the network device is used to reflect the operation status of the current network device and its constituent network, and the operation status reflected by the first KPI data includes but is not limited to: available links and the quality of the available links in the current network, the application class to be processed by the current network equipment, the quality of user experience, the policy configuration of the current network equipment, and the like.

1012. And comparing the first KPI data with second KPI data corresponding to the historical recommendation result, acquiring a data difference index based on the comparison result, wherein the value of the data difference index is positively correlated with the difference degree between the first KPI data and the second KPI data.

The control device compares the first KPI data with second KPI data corresponding to the historical recommendation result to obtain a data difference indicator, including but not limited to: preprocessing the first KPI data to obtain preprocessed first KPI data; and comparing the preprocessed first KPI data with second KPI data corresponding to the historical recommendation result to generate a data difference index.

Wherein, the pretreatment process comprises the following steps: unifying the first KPI data into a standard format. Since the first KPI data includes a plurality of different types of data and is stored in different formats in corresponding databases of the storage device, in order to process the first KPI data, the first KPI data is unified into a standard format. For example, the first KPI data is unified into a standard format of link bandwidth, packet loss rate, and delay indicator, which is used to indicate the quality of the current network.

Optionally, the historical recommendation result may be the situation that the policy recommendation condition is met last time, the KPI data corresponding to the situation that the policy recommendation condition is met last time is used as the second KPI data, and the preprocessed first KPI data and the second KPI data are compared to generate the data difference index. The data difference index is used for indicating the difference degree of the first KPI data and the second KPI data, and the value of the data difference index and the difference degree can be in a positive correlation relationship. The data difference index reflects the difference between the current state and the historical state of the network equipment and the network formed by the network equipment, for example: the first KPI data is the same as the second KPI data, and the control equipment judges that the current state of the network equipment and the network formed by the network equipment is not changed compared with the historical state.

1013. And obtaining candidate strategy configuration only when the data difference index meets the strategy recommendation condition.

Before the control device obtains the candidate policy configuration, the method further comprises: the control equipment determines whether the data difference index meets the strategy recommendation condition. The control device determines whether the data diversity indicator satisfies a policy recommendation condition based on the data diversity indicator, including but not limited to: generating a recommendation withholding value based on historical recommendation trigger information; determining whether the data difference index meets a strategy recommendation condition based on the data difference index, the recommendation withholding value and the service rule; and generating a recommendation trigger signal under the condition that the strategy recommendation condition is met.

The business rule is a series of rules which are stored by the control device and are formulated in the determination process of whether the policy recommendation condition is met, and the business rule can include but is not limited to: initial recommendation trigger time, tuning period and the like. The initial recommendation trigger opportunity indicates an opportunity to first determine whether the policy recommendation condition is satisfied, for example: the current network equipment and the network formed by the current network equipment just finish upgrading and updating at the current moment, and the current moment can be used as an initial recommendation trigger moment. The tuning period defines a time period for determining whether the policy recommendation condition is satisfied, and may be set based on experience or adjusted according to an application scenario.

The historical recommendation trigger information is information that the control device stores in the past each time the policy recommendation condition is satisfied. Optionally, the historical recommendation trigger information may include: and the time meeting the strategy recommendation condition in the past each time and the KPI data corresponding to the time. The recommendation withholding value is generated based on historical recommendation trigger information to reflect the frequency of meeting the policy recommendation condition.

Under the distributed forwarding architecture, the network management device can have at least one switching network board, and the data exchange among a plurality of interface boards is realized through the switching network board, so that the high-capacity data exchange and processing capacity is provided. Therefore, the data access and processing capacity of the network management device with the distributed architecture is larger than that of the network management device with the centralized architecture. Optionally, the network management device may also be in a form of only one board card, that is, there is no switching network board, and the functions of the interface board and the main control board are integrated on the one board card, at this time, the central processing unit on the interface board and the central processing unit on the main control board may be combined into one central processing unit on the one board card to perform a function after the two are superimposed, and the data switching and processing capability of the network management device in this form is low (for example, network devices such as a low-end switch or a router, etc.).
