ABSTRACT:
A method and device for wavelength conversion, wavelength buffering and label/header swapping. A wavelength buffer is used to provide for in-band wavelength conversion in, for example, a dense wavelength division multiplexing communications system. The same device may be used for label/header swapping without wavelength conversion.
