搭建了光突發交換測試系統，重點分析了在極限情況下的光突發交換系統核心調度模塊的處理能力最低要求。測試系統的研究對象是在光突發交換系統網絡控制信道上傳輸的突發控制分組；測試環境是有突發性的高負載業務流；測試結構是8個多波長邊緣節點和1個核心節點組成的復雜光突發交換系統。通過結果分析，找出了極限情況下控制系統需要的最低服務速率；然后提出了控制系統的優化設計方案。
關 鍵 詞 光突發交換; 邊緣節點; 核心節點; 最低服務速率

Abstract Optical Burst Switching is considered as an efficient switching technique in building the next generation optical Internet. But as far as we know, there is no research about the control system of the OBS core node with multi edge node under high traffic load.
This paper deals with the BHP to research the performance of the control system under such circumstance. A new simulation model is introduced and the performance of the OBS core node is evaluated. Based on the simulation results we can find the way to design the OBS control system, which can give satisfy throughout rate of the input BURST.
Key words optical burst switching; edge node; core node; lowest serve rate
