PROBLEM TO BE SOLVED: To make the reservation amount of network resources with communication quality guaranteed minimum.SOLUTION: A virtual network control system of the present invention comprises a control server, a physical node device, and a physical link device, and allocates virtual node capacity and a virtual node data rate requested by the physical node device to the physical node device and the physical link device via the control server. If the virtual node data rate at the physical link device changes, the virtual network control system reallocates the virtual node data rate.SELECTED DRAWING: Figure 1 |
