Abstract
A virtual network control method, for adaptively controlling a topology of a virtual network formed on a physical network in response to environmental changes in the virtual network, is provided with: a step of storing the Langevin equation, as a fluctuation equation, which models the dynamics of the topology of the virtual network as a variable for controlling the number of wavelength paths on the physical network; a step of designing control parameters included in the fluctuation equation; and a step of controlling the topology of the virtual network by applying the control parameters to the fluctuation equation to change an order parameter included in the fluctuation equation when environmental changes occur in the virtual network, and by transitioning the solution of the fluctuation equation between attractors determined by the deterministic term of the fluctuation equation due to the fluctuation term of the fluctuation equation.
