Abstract
A controller of the present invention specifies a transmission virtual node and a reception virtual node of packet data by acquiring from a switch, a reception notice of packet data transferred between virtual networks which are managed by different controllers. A managing unit combines the virtual networks managed by the different controllers by using the transmission virtual node and the reception virtual node as common virtual nodes. Thus, the whole virtual network which is controlled by the plurality of controllers using an open flow technique can be managed by one source.
