Optical transmission device, optical transmission system, and optical transmission method

摘要

The optical transmission device includes an N×N optical switch, an optical packet receiver and an optical packet generation unit. The N×N optical switch transmits data in which a plurality of optical signals each having a different wavelength is multiplexed. The optical packet receiver detects change in the number of wavelengths of optical signals constituting the data. The optical packet generation unit generates, when the change is detected by the optical packet receiver, data to be transmitted by the N×N optical switch, using optical signals for the number of wavelengths after the change.

1. An optical transmission device comprising:
a transmission unit that transmits data including a plurality of optical signals each including a different wavelength, the plurality of optical signals being multiplexed; a detection unit that detects change in a number of wavelengths of optical signals constituting the data; a generation unit that, when the change is detected by the detection unit, generates data to be transmitted by the transmission unit, using the optical signals for the number of wavelengths after the change; and a mediation unit that performs mediation of the data by obtaining or discarding each of electrical signals input from header analyzers that analyze a path of the data in accordance with arriving order of the electrical signals.
