Abstract: A control method is provided for controlling a load state of a physical link between two physical network nodes in a physical network. A physical link carries a plurality of virtual links, and a virtual link connects together two virtual nodes belonging to a virtual network. First and second metrics are associated with the virtual link. The control method includes the following steps implemented by one of the two physical network nodes: a step of detecting a load state of a physical link; a step of identifying a virtual link for which a present metric is the first metric; and a step of sending a command to the virtual node carried by the physical node and to which the identified virtual link is connected, the command requesting a modification of the present metric from the first metric to the second metric for the virtual link.
