FIG. 4 is a schematic flowchart of a device upgrading method according to Embodiment 4 of the present invention. As shown in Figure 4, the device upgrade method may include the following processes:

1. The network device regularly sends the first heartbeat message to the connection server.

Since the network device and the management and control server are located in different local area networks, they need to interact through the public network. When a network device interacts through the public network as a client, if a fixed public network port is mapped on the public network, the network device interacts through the fixed public network port. However, if there are multiple network devices, multiple public network ports need to be mapped, which occupies too many public network ports. Usually, the public network has limited ports open to network devices. In order to solve the above problems, in the embodiment of the present invention, instead of mapping a fixed public network port to the network device on the public network, the public network port is randomly assigned to the network device, but the communication link of the network device will not be fixed, and frequent occurrences of Variety. Therefore, the network device regularly transmits the communication link information to the connection server, so as to ensure the accuracy of the communication link information of the network device stored in the connection server.

In the implementation, the network device will actively connect to the connection server when it is started or after it is started. For example, the network device acts as a client connected to the server, and performs a TCP connection with the connected server. After the connection is successful, the network device regularly sends the first heartbeat message to the connection server.

2. The connection server updates the communication link information of the network device to the routing table of the network device.

After receiving the first heartbeat message, the connection server acquires first communication link information corresponding to the first heartbeat message, and stores the first communication link information as communication link information of the network device. The communication link information of the network device may include: the port on the network device that interacts with the public network, the public network is the public network port randomly allocated by the network device, the public network is the public network port mapped to the connection server, and the connection server connects to the public network port. Port for network interaction. Of course, if there are other devices such as routers and switches between the network device and the connection server, the communication link information of the network device may also include ports of these routers, switches and other devices, and so on.

The routing table of the network device can be preset in the connection server, and the communication link information of the network device can be stored in a key-value (key-value) manner in the routing table of the network device. The first heartbeat message sent by the network device has a corresponding source MAC address, and the source MAC address is the MAC address of the network device. For example, the first heartbeat message is a data packet, and the header of the data packet carries the source MAC address of the data packet. After the connection server obtains the communication link information of the network device, it obtains the source MAC address corresponding to the first heartbeat message (that is, the MAC address of the network device), and associates and stores the MAC address of the network device with the communication link information of the network device in the in the routing table of the network device. When storing, the MAC address of the network device is used as the key, and the communication link information of the network device is used as the value.

3. The connection server sends a first heartbeat response to the network device.

4. The control server regularly sends the second heartbeat message to the connection server.

Since the ports on the management and control server interacting with the connection server are randomly assigned, the ports will change at any time, so the communication link information of the management and control server will also change. Therefore, the control server regularly transmits the communication link information to the connection server, so as to ensure the accuracy of the communication link information stored in the connection server and the control server.

In the implementation, the control server will actively connect to the connection server when it is started or after it is started. For example, the control server acts as a client connecting to the server, and performs a TCP connection with the connecting server. After the connection is successful, the control server regularly sends a second heartbeat message to the connection server.

5. The connection server updates the communication link information of the control server to the routing table of the control server.

After receiving the second heartbeat message, the connection server acquires the second communication link information corresponding to the second heartbeat message, and stores the second communication link information as the communication link information of the management and control server. The communication link information of the management and control server may include: a port on the management and control server that interacts with the connection server, and a port on the connection server that interacts with the management and control server. Of course, if there are other devices such as routers and switches between the management and control server and the connection server, the communication link information of the management and control server may also include ports of these devices, and so on.

The routing table of the management and control server can be preset in the connection server, and the communication link information of the management and control server can be stored in the form of key-value (key-value) in the routing table of the management and control server. The second heartbeat message sent by the control server has a corresponding source MAC address, and the source MAC address is the MAC address of the control server. For example, the second heartbeat message is a data packet, and the header of the data packet carries the source MAC address of the data packet. After the connection server obtains the communication link information of the management and control server, obtain the source MAC address corresponding to the second heartbeat message (that is, the MAC address of the management and control server), and associate the MAC address of the management and control server with the communication link information of the management and control server. Control the routing table of the server. When storing, the MAC address of the control server is used as the key, and the communication link information of the control server is used as the value.

Every time the connection server receives the second heartbeat message, it updates the communication link information of the control server.

6. The connection server returns the first heartbeat response to the control server.

7. The network device reports the device information to the connection server, carrying the first destination MAC address.

After the network device is successfully connected, it reports its own device information to the connection server. In implementation, the network device packs the device information into a data packet, and the header of the data packet carries the first destination MAC address, and the first destination MAC address is the MAC address of the target control server to which the device information is to be sent.

8. The connection server searches for the communication link information corresponding to the first destination MAC address from the routing table of the management and control server.

After receiving the device information of the network device, the connection server parses the data packet to obtain the first destination MAC address corresponding to the device information. The connection server searches the routing table of the management and control server for communication link information corresponding to the first destination MAC address, and the communication link information corresponding to the first destination MAC address is the communication link information of the management and control server.

9. The connection server sends the device information to the management and control server based on the communication link information corresponding to the first destination MAC address.

10. The management and control server stores the equipment information of the network equipment into the database.

After receiving the device information of the network device, the management and control server analyzes the data and stores the device information of the network device into the database. The device information of the network device may include a MAC address, an IP address, a version number, a device name, a device model, a device type, and the like of the network device.

11. The management and control server transmits the equipment information of the network equipment to the front-end page of the management and control for display.

The management and control server can transmit the device information of the network device to the management and control front-end page for display. When displaying, only a part of the device information can be displayed. For example, the device name of each network device may be displayed on the page, so that the user may select a target device name for upgrading.

12. The management and control front-end triggers an upgrade, and transmits relevant data to the management and control server.

The user selects the device name of the network device on the management and control front end, and triggers the upgrade button, and the management and control front end can transmit the device name of the network device selected by the user to the management and control server.

13. The management and control server obtains the device information and upgrade information of the network device from the database.

Upgrade information corresponding to each device type is stored in the database. According to the device name transmitted by the control front end, the management and control server searches the database for the device information corresponding to the device name. The management and control server obtains the device type from the found device information, and then obtains the upgrade information of the network device corresponding to the device type.

14. The control server sends upgrade information to the connection server, carrying the second destination MAC address.

The control server obtains the MAC address of the network device from the found device information, uses the found MAC address as the second destination MAC address, and packs the upgrade information into a data packet, and the header of the data packet carries the second destination MAC address . The control server sends the data packet to the connection server.

15. The connection server queries the communication link information corresponding to the second destination MAC address from the routing table of the network device.

After receiving the upgrade information, the connection server parses the data packet to obtain the second destination MAC address corresponding to the upgrade information. The connection server searches the routing table of the network device for communication link information corresponding to the second destination MAC address, where the communication link information corresponding to the second destination MAC address is the communication link information of the network device.

16. The connection server sends the upgrade information to the network device based on the communication link information corresponding to the second destination MAC address.

17. The network device downloads the upgrade file from the management and control server according to the upgrade information, and performs the upgrade.

The upgrade information can include the version number of the upgrade file, the MD5 (Message Digest Algorithm, the fifth edition of the message digest algorithm) value of the upgrade file (the MD5 value is the MD5 value generated when the upgrade file is uploaded), and the URL (Uniform Resource Locator, Uniform Resource Locator), the file name of the upgrade file, and so on. The control server assembles these upgrade information into a JSON (JavaScript Object Notation, JS Object Notation) string.

After receiving the upgrade information, the network device obtains the URL for downloading the upgrade file, the network device generates an upgrade request carrying the URL, sends the upgrade request to the management and control server, and actively downloads the upgrade file from the download interface of the management and control server.
