Abstract

In this paper, we propose a novel scheduling scheme, namely Packet Preemptive Scheduling (PPS), which is designed to handle real-time (high priority) packets in WDM star networks. PPS allows high priority packets to displace the scheduled low priority (non-real-time) packets. By doing so, PPS guarantees that the high priority packets can always achieve the earlier transmission than the others so as to meet the QoS requirements. This scheme has the capability of handling channel collision and destination conflict. The performance of the PPS scheme has been extensively studied by means of numerical simulations.
