Publication number: 20220353232Abstract: Example data transmission methods and apparatus are described. In one example method, a data distribution point obtains a first correspondence between a first virtual extensible local area network identifier (VXLAN ID) and an address of a first terminal. The data distribution point receives a first VXLAN packet based on a tunnel of a first VXLAN, where the first VXLAN packet includes the first VXLAN ID and first data. The address of the first terminal is determined based on the first VXLAN ID carried in the first VXLAN packet and the first correspondence.
