<p>The one-to-one fixed relation between clients can be canceled and global resources such as wavelengths/path resources are used effectively by a WDM (wavelength division multiplexing) network system for an automatic wavelength control with an IP address. The WDM network system comprises an optical wavelength multiplexing (WDM) transmission line, a plurality of sub-networks each accommodating clients and a plurality of WDM nodes corresponding respectively to the sub-networks and connected with the optical wavelength multiplexing transmission line. Each of the WDM nodes includes a wavelength converting unit for controlling the oscillation wavelength in accordance with the address for specifying the destination with an IP address and a cross connect unit for cross-connecting a line to an adjoining WDM node for connection with the destination.</p> |
