摘要

This paper proposes an optical packet switch (OPS) with parametric wavelength converters (PWCs) that combines the advantages of static pump wavelength assignment (SPA) switch and dynamic pump wavelength selection (DPS) switch to trade off the performance in terms of packet loss rate and processing time. Since SPA switch has faster processing time than DPS switch, while DPS switch achieves high performance in term of packet loss rate. The combination of those schemes is an alternative for a network manufacture to adjust the network switch suit on user requirements. Simulation in limited environment is done to show the performance of hybrid configuration between SPA and DPS switches. The results of proposed scheme are better than SPA switch but not up to DPS switch in term of packet loss rate, while worse than SPA switch but not worse than DPS switch in term of processing time. However, the replacing one of dynamic PWC with Static PWC could decrease much processing time but effects to packet loss rates just a little bit worse. The results provide the useful information for switch manufacture in order to design the switch in variety specifications, which are expected to satisfy the various user requirements.
