PURPOSE: An Ethernet-based next generation optical transport network apparatus and a traffic grooming method of an apparatus thereof are provided to effectively a network resource by supplying the tragic grooming function with each flow. CONSTITUTION: An optical signal which is multiplexed wavelength division in which one or more optical demultiplexers is inputted from optical signal distributors(511, 512) is demultiplexed to each wavelength. A traffic grooming module(530) assigns a new optical virtual channel after separating optical virtual channels from the optical wavelength inputted from the light demultiplexer. An optical wavelength conversion module(560) assigns the new optical wavelength to the signal inputted from the traffic grooming module. One or more optical multiplexers(551, 552) multiplexes a plurality of optical wavelength signals inputted from the traffic grooming module to the wavelength division. |
