Embodiment Construction
[0017] In order to solve the problem of service interruption during terminal roaming, a three-layer roaming proxy method can be used. In this mode, the IP address of the terminal can remain unchanged after roaming, but the terminal sends and receives messages through the AC (WirelessAccess Point Controller, wireless controller) and the roaming AC, the ability to forward and process packets is limited by the AC. In addition, the message still carries the information of the original VLAN during the forwarding process. If the service is not interrupted, the configuration of the upper-layer device needs to be changed. When there are many upper-layer devices, it becomes extremely complicated to configure them one by one. In addition, when packets are forwarded across VLANs, the original VLAN information will be leaked, reducing network security.
[0018] In order to better solve the problem of service interruption during terminal roaming, an embodiment of the present invention prov...
