Abstract:
1. An optical packet switching system including a plurality of transmitting network elements for transmitting optical packet signals and a receiving network element for receiving the optical packet signals transmitted from the transmitting network elements, the receiving network element comprising: an optical signal-to-noise ratio (OSNR) acquiring unit configured to acquire an OSNR of each of the optical packet signals received; an average value calculating unit configured to calculate an average value of the OSNRs of optical packet signals received within a predetermined time duration for each of the plurality of transmitting network elements that are sources of the optical packet signals; and a difference information transmitter configured to calculate, for each of the plurality of transmitting network elements, a difference between the calculated average value thereof and an average value of the ONSRs of all of the optical packet signals received within the predetermined time duration, and configured to transmit the difference to a transmitting network element associated with the difference, wherein each of the transmitting network elements adjusts a characteristic of an optical packet signal to be transmitted in a manner such that the difference is reduced.
