Data transmission method and computer system

A computer system, comprising:

• a processor, and
• a memory configured to store non-transitory instructions, and in response to the nontransitory instructions being executed by the processor, causes the computer system to:
• determine that a first network address segment overlaps with a second network address segment, wherein the first network address segment is a network address segment of a subnet in which a target server is located, the target server is a server configured to run on a first virtual private cloud (VPC), the first network address segment belongs to a network address segment of the first VPC, and the second network address segment is a network address segment of a subnet in which a first electronic device is located;
• and
• create at least two subnets on the first VPC, wherein a network address segment of one of the at least two subnets on the first VPC does not overlap with the first network address segment or the second network address segment, and network interfaces in the at least two subnets on the first VPC are configured to sequentially forward a data packet being transmitted between the target server and the first electronic device thereby causing the data packet to be forwarded at least two times during transmission of the data packet,
• wherein the data packet is forwarded through each of at least two network interfaces of the network interfaces after IP address translation is performed, the at least two network interfaces of the network interfaces corresponding to the at least two subnets, and an IP address of each network interface of the at least two network interfaces of the network interfaces belongs to a corresponding subnet.
