Abstract:
1. A wavelength service providing apparatus in an all-optical network, constructed by a transmission device including an all-optical node, a transponder on a user side of the all-optical node, and a wavelength multiplexing and demultiplexing optical filter on a network side of the all-optical node, comprising: control means, provided in the all-optical node or the transponder, for sending a requested band information, obtained from a wavelength path setting request, to a multi-rate functional means and for sending a wavelength information selected according to the wavelength path setting request to a wavelength varying means based on the requested band information in the wavelength path setting request, link information in the network, and band limitation information with respect to filter wavelengths of the wavelength multiplexing and demultiplexing optical filter; multi-rate functional means, provided in the transponder, for sending a bit rate varying request to an optical transceiver in the transponder to set a bit rate of the optical signal generated to the network side according to the requested band information; and wavelength varying means, provided in the transponder, for sending a wavelength varying request to the optical transceiver to set a wavelength of the optical signal for the network side according to the wavelength information.
