ABSTRACT:
An optical packet switching system in which transmission quality, reliability, and system management in optical packet switching control are improved. An optical packet switch section includes semiconductor optical amplifiers as gate switches multistage-connected on paths along which optical packets sent from a plurality of input line cards are transmitted and performs optical packet switching by broadcasting the optical packets to a plurality of gate switches, by selecting the optical packets by ON/OFF gating operation of the gate switches, and by absorbing noise signals which flow along non-selected paths by putting gate switches at a final stage into the OFF state. A switch control section exercises ON/OFF drive control over the gate switches in the optical packet switch section on the basis of port connection requests from the plurality of input line cards so as to generate requested paths.
