Abstract: An optical transport hierarchy based optical transport system and a signal frame switching method of the system are provided to transmit a signal frame with a large capacity by controlling a cross-point directly without control of a processor by using a multiport cross point switch and a SDRAM method. A line card receives an optical transport hierarchy based dependent signal from a client and converts the received signal into a signal frame and transmits the signal frame through a plurality of line interfaces. An optical transport hierarchy switching unit includes a cross point switch to switch the signal frame received from the line card to the destination by the asynchronous method. A transmission and reception unit converts the switched signal frame to each dependent signal network signal frame and transmits the signal frame to outer dependent network.

Abstract: An apparatus for switching an OTH(Optical Transport Hierarchy) signal frame in an ATCA platform is provided to switch a large switching capacity and provide a multicast and ADM(Add and Drop Multiplexer) function to provide the same function as that of an existing SDH switch. A processor unit(200) is connected with a fabric interface unit of an ATCA(Advanced Telecom Computing Architecture) platform and controls ODU data received through an input port. An ethernet controller controls ethernet communication to the fabric interface unit. A cross point switch unit(220) is connected with a line card, an input/output unit of the ATCA platform, to cross-switch a 2.5Gbps signal between node slots. A chip set driver signal generating and controlling unit(230) is implemented as a circuit configuration for a control signal required for each function part for implementing an OTH unit switch, an address decoding logic for a bus with the processor unit, and a circuit of a processor bus converter for a processor connection unit of a switch element. A back board connection unit(240) uses a double star structure based on a switch slot including the fabric interface unit, and connects a management channel for managing each line card slot to a base channel to interface the 2.5Gbps signal. A duplex function part(250) interchangeably mounts/dismounts two switch units in the ATCA platform, performs switching on the switch units due to a failure, and generates a control signal to allow each line unit to select one of two received signals.

Abstract: PURPOSE: An optical buffer is provided to alternately install many optical delayers and optical reflectors, and to pass light through the optical layers and the optical reflectors, then to delay light of a desired wavelength as much as desired time, thereby preventing optical packets from colliding with each other. CONSTITUTION: An optical circulator(32) has at least 3 ports, outputs light incident on the first port to the second port, and outputs light incident on the second port to the third port. Many optical reflectors(33a-33n) are connected to the second port, have different central wavelengths, reflect light of the substantially same wavelength as a self central wavelength among incident lights, and output the reflected light toward the second port. Many optical delayers(34a-34n) are installed by turns with the optical reflectors(33a-33n), and delay the light incident from each of the optical reflectors(33a-33n). An optical converter(31) converts light of an optional wavelength into central wavelengths of the optical reflectors(33a-33n), and outputs the converted light to the first port.

Abstract: PURPOSE: A controller structure of an optical burst switching network is provided to introduce offset time for data transmitted through a channel on a WDM optical link, thereby minimizing setup time without buffering a data burst and magnifying bandwidth efficiency. CONSTITUTION: A header packet transceiver(602) extracts header information from burst CCG(Control Channel Group) data, and capsulates the rest burst CCG data in Ethernet frame. A packet frame generator(603) generates new header information, and makes CCG data to be transmitted. A multiple forwarder(604) obtains output port number information and output label information from which the made CCG data are outputted, and transmits the obtained information to an electric switch matrix. A multiple scheduler(606) extracts burst length information from the burst CCG data, determines switching time and start time of a header packet, and buffers the burst CCG data to transmit the data. A multiple burst header packet transmitter(608) reads the CCG data, and transmits the CCG data. A switching controller(607) transmits a control signal. An E/O(Electric to Optical) converter(609) converts the CCG data into an optical signal.
