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
