PROBLEM TO BE SOLVED: To reduce calculation time while suppressing reduction in allocation accuracy, in determining optimum allocation of a physical resource to a virtual network.SOLUTION: A virtual network control device 1, first, refers to topology information on a physical network of a communication network; calculates a shortest path from a node to another node; and determines that the calculated shortest path is taken as an arrangement for a logical link. The virtual network control device 1, secondly, determines a logical arrangement of nodes and a cost as a resource amount of the nodes for a virtual network by using mathematical programming, by changing a combination of logical arrangements of the nodes by using the calculated shortest path and topology information on the virtual network. |
