Abstract: PURPOSE: A scheduler for an optical burst switching router and a method thereof are provided to minimize burst data loss by performing a scheduling in arrival order of burst data. CONSTITUTION: Channel information including arrival time information, offset time information and burst data length information of a header packet into which a burst data is inputted is received(41). Processing order information of a scheduling is generated on the basis of the arrival time information of burst data generated on the basis of the arrival time information of the header packet and the offset time information(42). An optical switch switching duration information is generated on the basis of the arrival time information and length information of the burst data(43). Output channel information is generated to output burst data received from an optical switch on the basis of a difference between a previously reserved activation-end time of the optical switch and an arrival time of new burst data to a transmission channel of an optical transmission path(44). Control information for controlling an optical switch fabric is generated on the basis of the processing order information of scheduling, the switching duration information of optical switch and the output channel information(45).

Abstract: PURPOSE: A device for gain-clamped optical amplification of optical switching system is provided to deal with an optical power fluctuation due to a channel variation promptly in an optical switching system by using a controller for controlling at a high rate a laser diode which generates a pumping laser. CONSTITUTION: A tap coupler(310,311) divides an optical signal. An optical detector(320,321) converts the divided optical signal into an electric signal. A controller(360) controls an amplification gain of the electric signal. A laser diode(370,371) generates a pumping laser. An optical isolator(330,332) inputs the pumping laser signal into an EDF(Erbium Doped Fiber)(340,341). The EDF(340,341) amplifies the input optical signal. An ASE(amplified spontaneous emission) filter(350) filters the optical signal amplified in the EDF(340). An optical isolator(331) inputs the filtered optical signal into the EDF(341).
