Because the ports corresponding to the network devices on the public network are randomly allocated and the ports can change at any time, the communication link information of the network devices can also change, and therefore the connection service end needs to acquire and store the communication link information of the network devices at regular time so as to ensure the accuracy of the communication link information of the network devices. Because the ports on the management and control server, which interact with the connection server, are randomly allocated, and the ports can change at any time, the communication link information of the management and control server also changes, and therefore the connection server needs to acquire and store the communication link information of the management and control server at regular time, so as to ensure the accuracy of the communication link information of the management and control server.
In the embodiment of the invention, any applicable numerical value can be set according to actual experience as to the specific numerical value of the timing time. For example, the timing time may be set to be 1 second, 2 seconds, 3 seconds, 5 seconds, and the like, which is not limited in this embodiment of the present invention.
After the network device establishes connection with the connection server, the network device sends the device information corresponding to the network device to the connection server. And after receiving the equipment information sent by the network equipment, the connection service end searches the communication link information of the management and control service end according to the equipment information.

As shown in fig. 2, the device upgrade method may include the steps of:
Because the communication link information of the management and control server side changes, the management and control server side transmits the communication link information of the management and control server side to the connection server side at regular time. For example, the management and control server may transmit the communication link information of the management and control server to the connection server at regular time by sending a heartbeat message to the connection server.
And after receiving the equipment information sent by the network equipment, the connection server sends the equipment information of the network equipment to the management and control server based on the communication link information of the management and control server. And after receiving the equipment information of the network equipment, the management and control server stores the equipment information.
When the network device needs to be upgraded, the user may perform corresponding operations, such as selecting the network device, selecting an upgrade operation, and the like, at the management and control front end, so as to trigger an upgrade instruction for the network device.

As shown in fig. 3, the device upgrade method may include the steps of:
Since the communication link information of the network device changes, the network device transmits the communication link information of the network device to the connection service side at regular time. For example, the network device may transmit the communication link information of the network device to the connection server at regular time by sending a heartbeat message to the connection server.
And after the network equipment is successfully connected with the connection service end, the equipment information of the network equipment is sent to the connection service end. And after receiving the equipment information sent by the network equipment, the connection server sends the equipment information of the network equipment to the management and control server based on the communication link information of the management and control server.
When the network equipment needs to be upgraded, the management and control server side sends upgrading information corresponding to the network equipment to the connection server side, and the connection server side sends the upgrading information to the network equipment based on the communication link information of the network equipment. After receiving the upgrade information, the network device generates an upgrade request according to the upgrade information and sends the upgrade request to the management and control server. And the management and control server sends the upgrade file corresponding to the upgrade request to the network equipment.
And step 304, after receiving the upgrade file sent by the management and control server, upgrading by using the upgrade file.

In the embodiment of the invention, the connection server communicates with the network equipment based on the communication link information of the network equipment acquired at regular time, and communicates with the control server based on the communication link information of the control server acquired at regular time, so that the connection server can forward information related to equipment upgrading between the network equipment and the control server, and the control server can remotely upgrade the network equipment in different local area networks with the control server.
Example four
In the following, the device upgrade method is described in detail through the overall interaction process between devices.
Fig. 4 is a flowchart illustrating an apparatus upgrading method according to a fourth embodiment of the present invention. As shown in fig. 4, the device upgrade method may include the following processes:
1. the network equipment sends a first heartbeat message to the connection service end at regular time.
Because the network device and the management and control server are located in different local area networks, interaction needs to be performed through a public network. When the network equipment is used as a client to interact through a public network, if a fixed public network port is mapped on the public network, the network equipment interacts through the fixed public network port. However, if there are multiple network devices, multiple public network ports are mapped, which occupies too many public network ports, and in general, the ports of the public network that are open to the network devices are limited. In order to solve the above problem, in the embodiment of the present invention, a fixed public network port is not mapped to a network device on a public network, but a public network port is randomly allocated to the network device, but a communication link of the network device is not fixed and may change frequently. Therefore, the network device transmits the communication link information to the connection service terminal at regular time so as to ensure the accuracy of the communication link information of the network device stored in the connection service terminal.
In the implementation, the network device will actively connect with the connection server at or after the startup. For example, the network device serves as a client connected to the server, and performs TCP connection with the connection server. And after the connection is successful, the network equipment sends a first heartbeat message to the connection server at regular time.
2. And the connection service end updates the communication link information of the network equipment into a routing table of the network equipment.
And 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 equipment. The communication link information of the network device may include: the port of the network device interacting with the public network, the public network port randomly allocated by the public network for the network device, the public network port mapped by the public network for the connection service end, and the port of the connection service end interacting with the public network. Of course, if there are other routers, switches, and other devices between the network device and the connection service end, the communication link information of the network device may also include ports of these routers, switches, and other devices.
The connection server may preset a routing table of the network device, and the routing table of the network device may store communication link information of the network device in a key-value manner. The first heartbeat message sent by the network equipment has a corresponding source MAC address, and the source MAC address is the MAC address of the network equipment. For example, the first heartbeat message is a data packet, and a header of the data packet carries a source MAC address of the data packet. After the connection server obtains the communication link information of the network device, the connection server obtains a source MAC address (namely, the MAC address of the network device) corresponding to the first heartbeat message, and stores the MAC address of the network device and the communication link information of the network device into a routing table of the network device in an associated manner. When storing, the MAC address of the network device is used as a key, and the communication link information of the network device is used as a value.
And the connection service end updates the communication link information of the network equipment once every time the connection service end receives the first heartbeat message.
3. And the connection server side replies a first heartbeat response to the network equipment.
4. And the management and control server sends a second heartbeat message to the connection server at regular time.
Because the ports on the management and control server interacting with the connection server are randomly allocated, the ports will change at any time, and therefore the communication link information of the management and control server will also change. Therefore, the management and control server transmits the communication link information to the connection server at regular time, so as to ensure the accuracy of the communication link information of the management and control server stored in the connection server.
In implementation, the management and control server is actively connected to the connection server during or after the start-up. For example, the management and control server serves as a client connected to the server, and performs TCP connection with the connection server. And after the connection is successful, the management and control server sends a second heartbeat message to the connection server at regular time.
5. And the connection server updates the communication link information of the management and control server to a routing table of the management and control server.
And after receiving the second heartbeat message, the connection server acquires 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 server may include: the management and control server is provided with a port which is interacted with the connection server and a port which is interacted with the management and control server. Of course, if there are other devices such as routers and switches between the management server and the connection server, the communication link information of the management server may further include ports of these devices, and the like.
The connection server may preset a routing table of the management and control server, and the routing table of the management and control server may store communication link information of the management and control server in a key-value manner. And the second heartbeat message sent by the control server side has a corresponding source MAC address, and the source MAC address is the MAC address of the control server side. For example, the second heartbeat message is a data packet, and a header of the data packet carries a source MAC address of the data packet. And after the connection server obtains the communication link information of the control server, obtaining a source MAC address (namely the MAC address of the control server) corresponding to the second heartbeat message, and storing the MAC address of the control server and the communication link information of the control server in a routing table of the control server in an associated manner. During storage, the MAC address of the management and control server is used as a key, and the communication link information of the management and control server is used as a value.
And updating the communication link information of the pipe control server once by the connection server every time the connection server receives the second heartbeat message.
6. And the connection server side replies a first heartbeat response to the management and control server side.
7. And the network equipment reports the equipment information to the connection service end and carries the first destination MAC address.
And after the network equipment is successfully connected, reporting the equipment information of the network equipment to a connection server. In implementation, the network device packages the device information into a data packet, where a packet header of the data packet carries a first destination MAC address, and the first destination MAC address is an MAC address of a target management and control server to which the device information is to be sent.
8. And the connection service end searches the communication link information corresponding to the first destination MAC address from a routing table of the control service end.
And after receiving the equipment information of the network equipment, the connection service end analyzes the data packet and acquires a first destination MAC address corresponding to the equipment information. The connection service end searches the communication link information corresponding to the first destination MAC address from the routing table of the control service end, and the communication link information corresponding to the first destination MAC address is the communication link information of the control service end.
9. And the connection service end sends the equipment information to the management and control service end based on the communication link information corresponding to the first destination MAC address.
10. And the management and control server side stores the equipment information of the network equipment in a storage.
And after receiving the equipment information of the network equipment, the management and control server analyzes the data and stores the equipment information of the network equipment into a 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. And the management and control server transmits the equipment information of the network equipment to a management and control front-end page for display.
The management and control server side can transmit the equipment information of the network equipment to the management and control front-end page for display. When displayed, only a portion of the device information may be displayed. For example, the device names of the network devices may be displayed in a page, so that the user may select the target device name from the page for upgrading.
12. The management and control front end triggers upgrading and transmits related data to the management and control server.
The user selects the device name of the network device at 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. And the management and control server acquires the equipment information and the upgrading information of the network equipment from the database.
The database stores the upgrading information corresponding to each equipment type. And the management and control server searches the equipment information corresponding to the equipment name from the database according to the equipment name transmitted by the management and control front end. And the management and control server acquires the equipment type from the searched equipment information and then acquires the upgrading information of the network equipment corresponding to the equipment type.
14. And the management and control server sends the upgrading information to the connection server, and the upgrading information carries the second target MAC address.
And the management and control server acquires the MAC address of the network equipment from the searched equipment information, packages the upgrade information into a data packet by taking the searched MAC address as a second destination MAC address, and carries the second destination MAC address in the packet head of the data packet. And the management and control server sends the data packet to the connection server.
15. And the connection service end inquires the communication link information corresponding to the second destination MAC address from a routing table of the network equipment.
And after receiving the upgrading information, the connection service end analyzes the data packet and acquires a second target MAC address corresponding to the upgrading information. And the connection service end searches the communication link information corresponding to the second destination MAC address from the routing table of the network equipment, wherein the communication link information corresponding to the second destination MAC address is the communication link information of the network equipment.

The management and control server assembles the upgrade information into a JSON (JavaScript Object Notation) character string.
After receiving the upgrade information, the network device obtains the externally downloaded URL of the upgrade file, generates an upgrade request carrying the URL, sends the upgrade request to the management and control server, and actively downloads the upgrade file from a download interface of the management and control server. And after receiving the upgrading request, the control server analyzes and acquires the upgrading file corresponding to the URL and issues the upgrading file to the network equipment.
After receiving the upgrade file, the network device generates an MD5 value of the downloaded upgrade file, and obtains an MD5 value of the upgrade file in the previously received upgrade information. The network device compares the MD5 value of the downloaded upgrade file with the MD5 value of the upgrade file in the upgrade information. If the comparison result is consistent, the downloaded upgrade file is correct, so that the network equipment is upgraded by using the downloaded upgrade file; if the comparison result is inconsistent, it indicates that the downloaded upgrade file may have a problem, and therefore the network device does not temporarily upgrade with the downloaded upgrade file.
In the embodiment of the invention, the network equipment is upgraded through the Internet, the remote upgrade of the network equipment by the management and control service terminals in different local area networks can be realized, and a fixed public network port does not need to be mapped for the network equipment.
