In step 302, if the source device is a cloud device, the tunnel protocol information matched by the data transmission channel is obtained.

In step 303, the data information is encapsulated into a tunnel protocol data packet according to the tunneling protocol information.

In this embodiment, the data information can be sent to the target device through a data transmission channel set in advance. The data transmission channel is a dedicated channel preset between the cloud gateway device and the user equipment, and is dedicated to providing a communication link between the cloud gateway device and the user equipment, and may include various connection types, such as wired and wireless. Communication links or fiber optic cables, etc.

Specifically, first, tunneling protocol information matching the above data transmission channel can be acquired. The above tunneling protocol information may be obtained from a mapping table of a computing platform's computing resources and tunneling protocol information, such as a vxlan (virtual extensible LAN) vni value (VXLAN Network Identifier).

Then, the data information is encapsulated into a tunnel protocol data packet according to the tunnel protocol information, and the tunnel protocol data packet is a data packet generated by adding an outer packet header to the original data packet, and the outer packet header includes the address of the target device. Information, or address information of the gateway corresponding to the target device.

In step 304, the target user equipment of the data information transmission is parsed from the data information as the first target device.

In this embodiment, if the source device is a cloud device, it may be determined that the data information is transmitted from the cloud device to the user device. First, it is necessary to determine the target user equipment indicated by the above data information as the first target device. The target user equipment indicated by the data information is the final transmission destination of the data information. Generally, the data information carries the related information of the transmission target. Therefore, the target user equipment transmitted by the data information can be determined as the first target device by analyzing the data information.

In step 305a, the tunnel protocol data packet is sent to the first target device through the data transmission channel.

In step 305b, the tunnel protocol data packet is sent to the gateway corresponding to the first target device through the data transmission channel.

In this embodiment, the first target device may directly communicate with the cloud gateway device, or may communicate with the cloud gateway device through the user gateway device. When the first target device can directly communicate with the cloud gateway device, the cloud gateway device can send the tunnel protocol data packet to the first target device by using the foregoing preset data transmission channel, so that the first target device can use the tunnel protocol. The data packet is decapsulated, and after removing the outer packet header, the data information is obtained.

When the first target device needs to communicate with the cloud gateway device through the user gateway device, the cloud gateway device may send the tunnel to the user gateway device corresponding to the first target device by using the foregoing preset data transmission channel. The channel protocol packet is obtained by the user gateway device to decapsulate the tunnel protocol data packet, and after removing the outer packet header, the data information is obtained, and the data information is sent to the first target device.

Applying the foregoing embodiment, when the source device is a cloud device, the received data information is encapsulated into a tunnel protocol data packet according to the tunneling protocol information matched by the data transmission channel, and the target user equipment is determined, and the data transmission channel is used to target the user equipment or The tunnel protocol data packet is sent to the gateway corresponding to the target user equipment.

And the process of transmitting data to the target device is described in further detail, and the method includes the following steps:

In step 401, in response to receiving the data information, it is determined whether the source device from which the data information originated is a cloud device or a user device.

In step 402, if the source device is a user equipment, it is determined whether the data information includes an address resolution protocol ARP request.

In this embodiment, the cloud gateway device may further have an ARP (Address Resolution Protocol) proxy function, and the proxy function can process the ARP request of the user equipment. Therefore, if the source device is a user equipment, it may be further determined whether the data information includes an ARP request. ARP is an address resolution protocol, which is a TCP/IP protocol that obtains a physical address based on an IP address. The user equipment may send an ARP request including the target device IP address to the cloud gateway device to obtain the physical address of the target device, so that the target device may directly communicate with the target device through the preset data transmission channel based on the physical address of the target device.

In step 408, the physical address is returned to the source device for the source device to communicate with the third target device based on the physical address.

In this embodiment, if the source device is a user equipment, and the foregoing data information includes an ARP request, the physical address of the third target device (the target cloud device indicated by the ARP request) is found. Generally, in the local cache of the cloud gateway device, a mapping relationship between the IP address of the cloud device and the physical address may be stored. Therefore, the physical address of the third target device may be first searched from the cache. If the physical address of the third target device is not found in the cache, the ARP request may be broadcasted in the private network of the cloud computing platform to broadcast the ARP request, so as to find the third target device indicated by the ARP request. Physical address.

When the source device is the user equipment, if the data device does not include the ARP request, the data information may be decapsulated according to the tunnel protocol information matched by the data transmission channel that transmits the data information to obtain the original data information. And determining the target cloud device, and sending the original data information to the target cloud device. If the data information includes the ARP request, the physical address of the target cloud device can be provided to the user equipment through the ARP proxy function of the cloud gateway device, thereby further implementing mutual access between the cloud device and the user device, and avoiding the assignment to the user device. The waste of public resources caused by the public network IP address saves public resources.

If user equipment A does not have the function of a gateway device, The computing resource data is sent to the user gateway device corresponding to the user equipment A, and the user gateway device encapsulates the computing resource data into a tunnel protocol data packet, and sends the tunneling protocol data packet to the cloud gateway device in the cloud computing platform. Finally, the cloud gateway device decapsulates the tunneling protocol data packet to restore the computing resource data, and sends the computing resource data to the cloud device.

The user equipment A can also send an ARP request to the cloud gateway device, where the ARP request includes the IP address of the target cloud device, and the cloud gateway device can obtain a mapping relationship table from the local cache, where the mapping relationship table records the IP addresses of some cloud devices. Mapping of physical addresses. Find the physical address of the target cloud device from the mapping relationship table. The physical address of the target cloud device is returned to the user equipment A, and the user equipment A can directly communicate with the target cloud device through the data transmission channel according to the physical address to send or request to acquire computing resource data.

It can be seen that, by applying the foregoing solution, the cloud device and the user device can be mutually accessed without assigning a public network IP address to the cloud device, thereby saving public resources.
