Abstract: PROBLEM TO BE SOLVED: To provide a method and system capable of optical packet switching even in the case where optical data to enter to an optical packet switch is not in the form of packet but in the form of continuous data. SOLUTION: The optical switching method includes a step (401) of switching so that the number of input terminal is the same as the number of output terminal, a step (402) of detecting whether or not input terminals into which an optical packet is inputted, a step (403) of switching the optical packet into destination output terminals of the optical packet by the length of the optical packet when the optical packet has been inputted to one of input terminals in the step (402), a step (404) of determining whether or not there is other optical packets received from other input terminals and whose destination output terminal is an output terminal with the number switched at present when there are the input terminals into which the optical packet is not inputted in the steps above, a step (405) of switching the present input terminal to an idle output terminal when the result of the step (404) is YES, and a step (406) of maintaining the switched state of the present input terminal when the result of the step (404) is NO. All the inputted data independently of the packet form can be switched into output terminals without omission.
