Performance of Hybrid Pump-Wavelength Configurations for Optical Packet Switch With Parametric Wavelength Converters
This paper proposes an Optical Packet Switch (OPS) with Parametric Wavelength Converters (PWCs) that combines the advantages of the Static Pump wavelength Assignment (SPA) switch and the Dynamic Pump wavelength Selection (DPS) switch to realize the optimum trade off between packet loss rate and processing time. The SPA switch has faster processing time than the DPS switch but lower performance in terms of packet loss rate. Their combination allows a network installer to adjust the network switch to suit user requirements. Simulations in a limited environment confirm that the performance of the SPA-DPS combination lies between those of its constituents. Replacing one dynamic PWC with a static PWC can greatly decrease the processing time with only a slight drop in packet loss rate.
