Abstract: A system that includes a plurality of nodes to forward a data packet in a network, includes a controller to select at least a node dividing a data path of the data packet into a first path and a second path, from the nodes, based on a condition of the data path, and a node selected by the controller being capable of forwarding the packet to the first path and the second path according to an instruction from the controller. The second path includes a bypass path of the first path.
