Summary:PROBLEM TO BE SOLVED: To facilitate the batch control of a complicated virtual network and to automatically perform the reconstitution and the change of a virtual network. SOLUTION: In this system, plural ports 1 to 5 with which each node 21 to 31 is connected and switching hubs 11 to 13 having bridge functions are connected via an ATM network 10, prescribed ports are divided into groups between other switching hubs, the setting of a virtual LAN is performed and data is transmitted to a node to be a transmission origin and the node of the same group. In this case, a VLAN server 14 storing the MAC addresses of the nodes and VLAN identification data by making them correspond is connected with the ATM network, a batch control of all the nodes is performed on the VLAN server by the MAC addresses and the reconstitution and the change of the VLAN are performed.
