Abstract :
In this paper, a novel optical packet switch (OPS) architecture is proposed and its scheduling algorithm is implemented and analyzed. The proposed architecture makes use of shared wavelength exchange optical crossbars (WOCs) to reduce wavelength conversion complexity. Simulation results show that, under heavy traffic loads, the conversion cost of the proposed OPS architecture is only 25% of that of a typical OPS architecture. Moreover, under low traffic loads, the conversion cost of the proposed architecture can be reduced to half of that of typical OPS designs.
