Example Embodiment
[0048] See figure 1 , Is a network architecture diagram in an exemplary embodiment of the present invention, where AC1 and AC2 belong to different groups of the same ESS, and three-layer intercommunication can be realized through MC. In the existing networking environment, AC1 and AC2 can be used as DHCP servers to assign addresses to STAs, but AC1 and AC2 assign addresses to different network segments. For example, the network segment of AC1 is 1.0.0.1 and the network segment of AC2 is 2.0. 0.1. Assuming that the STA is under AP1 before roaming, the DHCP server corresponding to the STA is AC1 / 1.0.0.1. When the STA establishes a session connection with the target server, the assigned private network address is 1.0.0.100 and the gateway is 1.0.0.1. When the STA roams to AP2, the DHCP server corresponding to the STA is AC2 / 2.0.0.1, and its gateway should be 2.0.0.1. Since the original private network address 1.0.0.100 is no longer available, the STA needs to apply to AC2 again T...
