[0032] Embodiment 1

[0033] Figure 1 A schematic diagram of the structure of an edge network management system is provided for the first embodiment of the present invention. This embodiment is applicable to situations where multiple services are difficult to handle in a unified manner. The method can be executed by an edge network management device, which can be implemented in the form of hardware and / or software. The edge network management device can be configured in an electronic device with data processing capabilities. Figure 1 As shown, the system includes a topology management module 110, a basic network management module 120, a database management module 130, a status monitoring module 140, a log management module 150, a southbound interface management module 160, and a northbound interface module 170:

[0034] The topology management module 110 is used to establish or delete a connection with each IoT device.

[0035] The basic network management module 120 is used to perform network management on each switch device, and the switch device is connected to the edge network management system;

[0036] The database management module 130 is used to obtain the historical operation and operation data of the topology management module and the basic network management module, and send it to the target object through the northbound interface module 170;

[0037] The status monitoring module 140 is used to detect the operating status of each switch device and send the detection result to the target object through the northbound interface module 170;

[0038] The log management module 150 is used to determine and store the operation logs of each IoT device and send them to the target object through the northbound interface module 170;

[0039] The southbound interface management 160 is used to perform data interaction with each switch device through a standard RESTFUL protocol.

[0040] Since there are a large number of services in the power business with quite different communication interfaces, communication protocols, operating environments, etc., a system that is compatible with these services is needed to achieve control and detection of these services, thereby ensuring the stable operation of the power business.

[0041] Therefore, the present application provides an edge network management system, which includes an application layer, a controller, and a link layer. The application layer provides the target object with information such as the operating status of the edge network management system, the operating status of each IoT device, and each switch device. And through the northbound interface, a visual user management interface can be set for the target object in the application layer, so that the user can operate different services simply and directly, input configuration information, monitor network status, etc. For the setting method of the visual user management interface, it can be programmed through an existing programming language, and this application does not limit this.

[0042] The edge network management system of the present application includes a topology management module 110 , a basic network management module 120 , a database management module 130 , a status monitoring module 140 , a log management module 150 , a southbound interface management 160 and a northbound interface module 170 .

[0043] In the topology management module 110, it is mainly responsible for connecting the IoT devices that need to be managed to the edge network management system, or removing the IoT devices that have been connected to the edge network management system.

[0044] The basic network management module 120 is mainly responsible for network management of switch devices that have been connected to the edge network management system, including but not limited to managing VLANs, maintaining ports of each switch device, and performing static physical geological configuration for each switch device and the IoT devices connected to the switch device.

[0045] The database management module 130 is used to implement data storage of the edge network configuration management device. Specifically, the database management module 130 is responsible for storing and managing data of the topology management module 110 and the basic network management module 120 .

[0046] The status monitoring module 140 is used to perform real-time or periodic detection on the operation of each switch device, and the detection result should be sent to the target object through the northbound interface module 170.

[0047] The log management module 150 is mainly responsible for obtaining the operation logs of each IoT device, storing the operation logs of each IoT device, and sending them to the target object through the northbound interface module 170.

[0048] The southbound interface management 160 is mainly used to communicate data with each switch device using a standard RESTFUL protocol.

[0049] Among them, the standard RESTFUL protocol is a software architecture style based on the HTTP protocol, which is used to design network applications and APIs, and enables data exchange between applications through standard HTTP methods.

[0050] Optionally, the content acquired by each of the above modules can be sent to the target object through the northbound interface module 170 and displayed according to a pre-set display method, including but not limited to graphic display, animation display, etc.

[0051] In an optional solution, optionally, the northbound interface module 170 further includes a user interaction unit:

[0052] The user interaction unit is used to provide operational feedback to the target object through the REST API interface.

[0053] In order to ensure that the edge network management system can process more timely and flexibly, the northbound interface module 170 can also provide a REST API interface and provide timely feedback on the operation of the target object through the REST API interface.

[0054] In an optional solution, optionally, the topology management module 110 includes a static topology establishing unit and a dynamic topology discovering unit:

[0055] A static topology establishment unit, used to create or delete connections between individual IoT devices and the edge network management system;

[0056] The dynamic topology discovery unit is used to determine the link connection relationship of each switch device through the link layer discovery protocol.

[0057] The topology management module contains two units, namely the static topology establishment unit and the dynamic topology discovery unit. Among them, the static topology establishment unit is mainly used to create or delete the connection between each IoT device and the edge network management system. The creation and deletion process can be created by the target object through the user management interface in the application layer, by dragging and dropping.

[0058] In addition, a dynamic topology discovery unit is included, which provides a link layer discovery protocol and can determine the link connection relationship of each switch device. The link layer discovery protocol can be a technology for automatically discovering devices and their link information in a local area network.

[0059] Based on the above embodiment, optionally, the basic network management module includes a network management unit, a port configuration unit and a physical address configuration unit:

[0060] A network management unit is used to obtain network configuration information stored in each switch device;

[0061] A port configuration unit is used to obtain port information on each switch device;

[0062] The physical address configuration unit is used to obtain the static MAC information stored on each switch device.

[0063] The basic network management module includes at least three units, namely a network management unit, a port configuration unit and a physical address configuration unit.

[0064] The network management unit is mainly used to determine the network configuration information corresponding to each switch device, including but not limited to IP address, subnet mask, gateway, routing configuration, and VLAN configuration. The physical address configuration unit is mainly used to determine the physical address of each switch device. The port configuration unit is mainly used to obtain the port information on each switch device, including but not limited to port protocol, port type, port number, etc.

[0065] In addition, the network management unit can also be used to configure the global VLAN or configure the VLAN information of each port and send it to each switch device.

[0066] Based on the above embodiment, optionally, the status monitoring module includes a device management module:

[0067] The device management module is used to determine the operating status of each switch device.

[0068] Based on the above embodiment, optionally, the state monitoring module includes a state management unit:

[0069] The status management unit is used to determine the online rate, CPU utilization, maximum upstream flow, and maximum downstream flow of each switch device.

[0070] Since the transmission of data in the Internet of Things often depends on the normal operation of switch devices, the online rate, CPU utilization, maximum upstream flow, and maximum downstream flow of each switch device can be determined through the status management unit.

[0071] Based on the above embodiment, optionally, the status monitoring module includes a port traffic statistics unit:

[0072] The port traffic statistics unit is used to determine the traffic sent and received by each port of the switch device.

[0073] In addition, the receiving and sending traffic of different ports can also be counted in the same way through the port traffic statistics unit.

[0074] The contents determined by each unit and each module can be displayed by setting a visual user management interface for the target object in the application layer. The IoT devices and switch devices connected in this application need to support southbound interface protocols such as RESTFUL and NETCONF and open programmable interfaces, and be able to receive control instructions from the edge network management system to perform operations such as data forwarding and flow control.

[0075] By adopting the solution of this application, the control plane of the network can be separated from the data forwarding plane through the edge network management device, making network management more flexible and efficient. In addition, each IoT device and switch device can be managed and scheduled in a unified manner to improve the configurability and scalability of the network. In addition, through the standard southbound interface protocol, the network administrator can customize the configuration and management of the network through software programming. In the power IoT, these interfaces can be used to achieve communication and control with various power equipment, improving the compatibility and scalability of the network.
