<p><P>PROBLEM TO BE SOLVED: To realize general node network control applicable to the control function of a Peer model network node device, especially, to cooperated operation to be realized between various hierarchies such as frame, relay, asynchronous transfer mode (ATM), SDH, wavelength path, wavelength group path and fiber path. <P>SOLUTION: By using a path management function part equivalently related to a virtual high-order path and a physical high-order path, the fluctuation of a traffic capability with accommodation switching between a low-order path and a high-order path is relaxed. <P>COPYRIGHT: (C)2003,JPO</p> |
