Abstract

Burst-outputted performance will be affected by the outputting scheme in optical burst switching (OBS) core nodes. In this paper, we have evaluated the performance of an improved burst-outputted scheme in an OBS core node, in which fiber delay lines (FDLs) based limited optical buffer has been equipped. Different from the previous works which only consider the same probability to select output-port for burst, the proposed scheme gives a burst-outputted process based on different port selected probability. Simulation results have indicated that, performance evaluation parameters are changed with the output-port selected probability and the different number of FDLs in an optical buffer.
