摘要:
A network control system may be embodied in various elements of a communication network which communicates optical signals multiplexed by wavelength division multiplexing (WDM). In a preferred embodiment of the invention, the network control system limits a number of channel wavelengths actually used for communicating the optical signals to an end node to a highest number N of separable channel wavelengths at the end node. In another preferred embodiment of the invention, the network control system controls and modifies, as necessary, data rates carried over channel wavelengths multiplexed by WDM in order to reduce interference and improve performance of the communication network.
