<p>PROBLEM TO BE SOLVED: To surely communicate information between a plurality of computers, namely nodes in a system for manufacturing glass container, etc. SOLUTION: A network is constituted for connecting nodes A, B, and AA to each other and each node has a local virtual network process. The local virtual network process of the node A informs the local virtual network processes of the other nodes B and AA that a data base is opened or closed at the node A when the data base is opened or closed. When it is informed, the nodes B and AA generate or destroy virtual data base entries. Then the connection between the node A and the nodes B and AA is established so as to maintain the communication between the data base of the node A and the virtual data base entry of the node B or AA. When a plurality of nodes exists in different networks, the communication is made through a repeater.</p> |
