Ethernet-based next generation optical transport network apparatus and traffic grooming method thereof

An Ethernet-based next generation optical transport network apparatus comprising:

• a subscriber network interface configured to provide an interface with a subscriber network;
• one or more optical signal distributors configured to branch a wavelength division multiplexed (WDM) optical signal input from an adjacent node;
• one or more optical demultiplexers configured to demultiplex the WDM optical signals which have been input from the optical signal distributors, by wavelengths;
• a traffic grooming module configured to classify Ethernet frames and TDM frames, which have been input from the subscriber network interface, by the flows and allocate virtual optical channels, and separate virtual optical channels from an optical wavelength which has been input from the optical demultiplexer and allocate new virtual optical channels;
• an optical wavelength conversion module configured to allocate a new optical wavelength to a signal input from the traffic grooming module;
• one or more optical multiplexers configured to perform wavelength division multiplexing (WDM) on a plurality of optical wavelength signals input from the traffic grooming module;
• an optical wavelength switching module configured to switch optical wavelengths input from the optical signal distributor and the optical multiplexer;
• and
• a control module configured to generate a control signal for controlling the traffic grooming module, the optical wavelength conversion module, and the optical wavelength switching module based on resources available in a network, and provide the generated control signal.
