Patent ID: 8837942

Claim:
A packet-optical integrated transport apparatus comprising: a packet transmitter for outputting single-wavelength signal multiplexed to a predetermined channel on the basis of packet traffic or circuit traffic input from a metro access region; an optical transmitter for multiplexing the single-wavelength signal output from the packet transmitter to a multi-channel wavelength signal and adding or dropping the multiplexed multi-channel wavelength signal to or from a node; and a system controller configured for transmitting constituent element initialization information to the packet transmitter and the optical transmitter and receiving constituent element operation status information, wherein: the packet transmitter includes an Ethernet unit configured for outputting connection-oriented Ethernet (COE) tunnel information by using the packet traffic; a packet switch unit checking a destination of the packet traffic from the COE tunnel information output from the Ethernet unit and switching the packet; an Ethernet-optical transport hierarchy (OTH) unit for analyzing the COE tunnel information and forwarding the switched packet from the packet switch unit to a corresponding port; and an OTH unit for receiving the circuit traffic, to superpose traffic on an assigned single wavelength, and outputting the traffic.
