Abstract
A control apparatus according to an embodiment is a control apparatus that embeds a virtual network for implementing provision of a service on a physical network, the control apparatus including: a first acquisition unit that acquires a predicted value of an amount of traffic of the service and a predicted value of an amount of power including renewable energy usable by each of physical nodes constituting the physical network; a second acquisition unit that acquires information regarding the physical network; a solution calculation unit that calculates an optimal solution of a 2-stage robust optimization problem regarding allocation of virtual nodes constituting the virtual network to the physical nodes and route determination between the virtual nodes to minimize a link congestion rate representing a maximum value of a utilization rate of a link constituting the physical network and a node power congestion rate representing a maximum value of a power consumption rate of a node constituting the physical network on the basis of the predicted value of the amount of traffic, the predicted value of the amount of power, and the information regarding the physical network; and a control unit that controls the virtual network embedded in the physical network on the basis of the allocation of the virtual nodes and the route determination that are represented by the optimal solution.
