In some embodiments, the client device 30 may collect network information related to the local area network NW3 and upload the network information to the central office device 20 for query. For example, if the client device 40 wants to obtain the network information of the local area network NW3, the client device 40 may send a network service request x1 to the central office device 20. The central office device 20 can forward the network information of the local network NW3 uploaded by the client device 30 to the client device 40 according to the network service request x1. Specifically, the client device 30 can collect the network information of the local area network NW3 through the data integration module 323 and send the network information to the data transmission module 321. The above network information can be associated with the client device 30 Monitoring item data model 324, in other words, the network information is related to the monitoring item that the user of the client device 30 wants to monitor. On the other hand, the central office device 20 can also send a message to the client device 30 according to the requirements of the central office device 20 or the client device 40 to specify the content of the network information that the data aggregation module 323 needs to collect. The data transmission module 321 can upload the network information of the local network NW3 to the central office device 20 through the transceiver 330.

The API management module 221 of the central office device 20 can receive the network service request x from the client device 30 through the transceiver 230 and send a service request response y to the client device through the transceiver 230 in response to the network service request x 30.

Specifically, after the network service request x, the data collection module 222 of the central office device 20 can determine that the network service request x is associated with the wide area network NW2, the local area network NW4, and/or others managed by the central office device 20 Local area network. Then, the data collection module 222 may collect network information corresponding to the wide area network NW2, the local area network NW4, and/or other local area networks managed by the central office device 20 according to the network service request x. The above-mentioned network information is related to the monitoring item data model 324 of the client device 30. In other words, the network information is related to the monitoring items that the user of the client device 30 wants to monitor. According to different circuit classifications, the data collection module 222 can be implemented by technologies such as virtual private network (VPN), software-defined wide area network (SDWAN) or broadband circuit, and the invention is not limited to this .

Specifically, the service request response y may include network information of the wide area network NW2 (or local area network NW4). The topology module 322 of the client device 30 can respond to the network information of the wide area network NW2 (or the local area network NW4) provided by y and the network information of the local area network NW3 collected by the data aggregation module 323 according to the service request Generate cross-region topology maps, which can completely present the information of monitoring items related to the local area network NW3 and wide area network NW2 (or local area network NW4), and/or regional network NW3 and wide area network Network information such as the connection relationship between the road NW2 (or local area network NW4).

In some embodiments, the client device 30 needs to pass the authentication of the central device 20 before it can obtain a service request response y including network information from the central device 20. Specifically, the data transmission module 321 of the client device 30 can transmit the identity authentication information of the client device 30 to the central office device 20 through the transceiver 330. The client device 30 can receive the service request response y from the central office device 20 through the transceiver 330 in response to the identity authentication information being correct.

On the other hand, the API management module 221 of the central office device 20 can receive the identity authentication information of the client device 30 from the client device 30 through the transceiver 230, and determine the identity authentication information of the client device 30 according to the authentication authorization data model 224 is it right or not. If the identity authentication information is correct, it means that the client device 30 is a legitimate network service user. According to this, the API management module 221 can send the service request response y to the client device 30 through the transceiver 230 based on the correct identity authentication information of the client device 30.

ISP定義出此授權資料模型，當客戶端所在的區域網路通過認證後，取得此由ISP 配發的授權資料，再用此授權資料，向ISP進行查詢，其中API管控模組221根據「auth」括弧內的「user/token」之內容來進行身分認證資訊的判斷、「Group_A」括弧內的「server」代表對應之區域網路被授權的拓樸查詢範圍。V、S及B分別代表VPN、SDWAN及寬頻電路。 Specifically, the storage medium 220 of the central office device 20 may store the authorization data model 224. The authorization data model 224 may include various parameters set by the ISP, such as the name of the client device with the query authority of the network information of the wide area network or other local area network, the topological query range of the client device that is authorized, etc. Related parameters. Based on the authorization data model 224, the API management module 221 can determine whether the client device 30 has a query authority (ie, the client device 30 is a legitimate network service user) and is authorized based on the identity authentication information of the client device 30 Of the topological query range. Table 1 describes setting examples of the authorization data model 224. Table 1

The ISP defines this authorization data model. After the client’s local area network passes the authentication, the authorization data distributed by the ISP is obtained, and then the authorization data is used to query the ISP. The API management and control module 221 is based on "auth The content of "user/token" in the brackets is used to judge the identity authentication information, and the "server" in the brackets of "Group_A" represents the authorized topology query range of the corresponding local area network. V, S, and B represent VPN, SDWAN, and broadband circuits, respectively.

If the client device 30 has query authority, the API management module 221 may send a service request response y to the client device 30 through the transceiver 230, where the service request response y includes the topology query associated with the client device 30 being authorized Information about the scope.

In step S410, the client device sends a network service request to the local end device, where the client device corresponds to the local area network and the local end device corresponds to the wide area network. In step S420, a service request response is sent in response to the network service request. In step S430, the first network information corresponding to the local area network and the second network information corresponding to the wide area network are monitored in response to the service request.
