Description

Technical Field

[0001] The embodiment of the present invention relates to the field of communication technology, and in particular to a method for automatic cascading management of network devices based on websocket. Background Art

[0002] With the rapid development of network data, network traffic has surged, various complex network applications have emerged, and the management requirements for network equipment have become increasingly higher.

[0003] In the prior art, users usually control multiple network devices at the terminal, manage each network device, and query the device status information. Users need to know the connection status of each device, and the management is complicated, which can no longer meet the needs of complex network applications for network device management. Therefore, the market urgently needs a more convenient cascade management method. Summary of the invention

[0004] In order to meet the personalized needs of users, improve the convenience of cascade device management, and reduce the difficulty of use for users, the present invention provides a method for automatic cascade management of network devices based on websocket in view of the defects of the prior art. The user only manages one network device (main device). When there are other devices in the network, the main device actively establishes a connection with other devices, and the main device performs cascade management between devices, which can greatly reduce the complexity of user management.

[0005] On one hand, the present invention automatically detects whether a cascade device exists, including: Generate device IP address based on device information (device location, device SN number), send multicast message (carrying device IP address, device status information) to specific multicast group; receive messages in specific multicast group, parse message content to obtain cascade device IP address and status information; save and update main device address information; obtain cascade device information.

[0006] Another aspect of the present invention provides automatic creation of a cascade device management link, including: The master device creates a websocket server; the slave device creates a websocket connection request to the master device based on the device status and device IP address obtained by parsing the multicast message; the master device receives the websocket handshake information of the slave device and saves the websocket connection; if the slave device is not online, the master device receives the websocket disconnection information of the slave device and deletes the corresponding websocket connection; if the slave device updates the master device address obtained by parsing the multicast message, the websocket connection is disconnected and a websocket connection request is created to the new master device.

[0007] Another aspect of the present invention automatically manages cascaded devices. It includes: The user queries the connection status of all devices in the network from the master device; the user sends a device operation command to the master device as needed; the master device receives the operation command, determines that the operation object is itself, processes the message, and returns the user's operation result; the master device receives the operation command, determines that the operation object is other slave devices, forwards the message to the slave device, the slave device performs the corresponding operation and returns the operation result; the master device receives the slave device's operation result and forwards the operation result to the user.

[0008] Compared with the prior art, the technical solution of the present invention has the following significant beneficial effects: 1. The user only manages one network device (master device). When there are other devices in the network, the master device actively establishes connections with other devices and performs cascade management between devices, which can greatly reduce the complexity of user management.

[0009] 2. Meet the personalized needs of users, improve the convenience of cascade device management, and reduce the difficulty of use for users. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Step 2: Encapsulate the network address and device status into a data packet and send a multicast message to the specified multicast group.

[0017] Step 3: Monitor the message of the specified multicast group on the port and determine whether the message is correct.

[0018] Step 4: Parse the received multicast message, obtain the cascade device information, and save the main device address.

[0019] This method only needs to detect the cascade device address and establish a websocket connection to automatically implement cascade device management.

[0020] Figure 2 A flowchart of a method for creating a cascade device management link is provided in an embodiment of the present invention, such as Figure 2 As shown, the method includes: Step 1: The master device creates a websocket server and listens to the port.

[0021] Step 2: After the slave device detects the master device address, if it is the first time to detect the master device address, a websocket client connection is created.

[0022] Step 3: If the master device receives the handshake signal from the slave device, it saves the websocket client link.

[0023] Step 4: If the slave device goes offline, the master device receives the slave device websocket disconnection information and deletes the websocket information.

[0024] Step 5: If the slave device updates the master device address obtained by parsing the multicast message, disconnect the websocket connection and create a websocket connection request to the new master device.

[0025] Figure 3 A flow chart of a method for automatic cascading management of network devices based on websocket provided by an embodiment of the present invention, such as Figure 3 As shown, the method includes: Step 1: Each device is connected to the network, and the user queries the connection status of all devices in the network from the main device.

[0026] Step 2: The user sends a device operation command to the main device as needed.

[0027] Step 3: The master device receives the operation command, determines that the operation object is itself, processes the message, and returns the user operation result.

[0028] Step 4: The master device receives the operation command, determines that the operation object is another slave device, forwards the message to the slave device, and the slave device performs the corresponding operation and returns the operation result.

[0029] Step 5: The master device receives the operation result from the slave device and forwards the operation result to the user.
