  • Optical switching method and system therefor
    Patent number: 7174101
    Abstract: A method capable of optical packet switching even in a case where physical optical data in an optical packet switch has not the shape of a packet but the shape of continuous data, and a system therefore are provided. The optical switching method includes the steps of (a) detecting input terminals into which an optical packet is input, of an optical switch and switching the optical packet to destination output terminals of the optical packet, and (b) when there are the input terminals into which the optical packet is not inputted in step (a), detecting other input terminals into which the optical packet, which direct an output terminal among the plurality of output terminals connected to the input terminals, is inputted, and searching a blank output terminal and switching dummy data from the input terminal to the blank output terminal.
