Abstract
A VLAN control system is provided, which comprises: a remote access server, connected to a home network in the VLAN having a global network, for controlling communication between any moved terminal and the home network with reference to a management table for indicating a location of each terminal under connection; a remote access client, connected to each remote network, for controlling communication between the remote network and the global network with reference to a management table for indicating a correspondence relationship between each terminal which is connected to the remote network and the home network; and a VLAN management server, connected to the global network, for managing packet transmission and the location of each terminal with reference to a management table for indicating a correspondence relationship between each terminal and the remote access server and for indicating a location of each terminal under connection. In the control system, disconnection of a terminal which has been moved to a remote network is detected, without any special function at the terminal side, based on timing information of a packet transmitted from the terminal or connection information if the terminal is further moved to another remote network. A VLAN control method corresponding to the above system is also provided.
