Abstract
Information for performing path control is added to a signaling message used in a network including a higher-level path which accommodates a lower-level path. When a state change occurs in the higher-level path, a communication device extracts using the information a lower-level path to be controlled for the same control item as the control item indicating the state change in the higher-level path. A path to be controlled is selected from among the lower-level paths accommodated in the higher-level path. By controlling the extracted path, a plurality of paths can be easily controlled when there are accommodation relationships among layers.
