Packet processing method and apparatus based on tunneling technology

A computing device, comprising a processor, wherein the processor is coupled to a memory, and the processor is configured to store instructions, so that when the instructions are executed by the processor, the computing device is enabled to:

• obtain first tunnel information, wherein the first tunnel information comprises a first tunnel destination IP address, the first tunnel destination IP address is an IP address of the gateway, the cloud management platform is configured to manage an infrastructure that provides a cloud service, a first network is deployed on the infrastructure, and the first network and a second network are connected via the gateway, wherein a first host is deployed in the first network, a second host is deployed in the second network, and a network address conflict exists between the first network and the second network;
• and
• establish a first tunnel between the first network and the gateway based on the first tunnel information, wherein a service packet generated in a running process of the first host is transmitted to the gateway through the first tunnel, and a destination IP address of the service packet is an IP address of the second host, wherein
• forward the service packet to the second host based on the first tunnel information and the IP address of the second host.

A computing device cluster, comprising at least one computing device, wherein the computing device comprises a processor, the processor is coupled to a memory, the processor is configured to store instructions, and when the instructions are executed by the processor, the computing device cluster is enabled to perform:

• obtaining, by a cloud management platform, first tunnel information, wherein the first tunnel information comprises a first tunnel destination IP address, the first tunnel destination IP address is an IP address of a gateway, the cloud management platform is configured to manage an infrastructure that provides a cloud service, a first network is deployed on the infrastructure, and the first network and a second network are connected via the gateway, wherein a first host is deployed in the first network, a second host is deployed in the second network, and a network address conflict exists between the first network and the second network;
• establishing, by the cloud management platform, a first tunnel between the first network and the gateway based on the first tunnel information, wherein a service packet generated in a running process of the first host is transmitted to the gateway through the first tunnel, and a destination IP address of the service packet is an IP address of the second host;
• and
• forwarding, by the gateway, the service packet to the second host based on the first tunnel information and the IP address of the second host.
