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.
A control system for a virtual local area network (VLAN) in which a home network to which one or more terminals are ordinarily connected, and at least one remote network to which said terminals are connected when they are moved, are connected with each other via a global network, said system comprising:
A control method used in a virtual local area network (VLAN) system in which a home network to which one or more terminals are ordinarily connected, and two or more remote networks to which said terminals are connected when they are moved, are connected with each other via a global network, wherein:
A virtual local area network (VLAN) management server used in a VLAN system in which a home network to which one or more terminals are ordinarily connected, and two or more remote networks to which said terminals are connected when they are moved, are connected with each other via a global network, said server connected to the global network, said server having an IP address for the global network, and also having a management table for indicating a correspondence relationship between each terminal and a remote access server of the remote network and for indicating a location of each terminal under connection, and said server comprising:
