Abstract

This paper presents a new scheduling protocol for WDM star networks. The new protocol (Priority Scheme Earliest Available Time Scheduling -PS-EATS) is based on the previously proposed EATS protocol which assigns the earliest available data channel to each node that has a message to transmit. PS-EATS modifies the order in which the nodes´ requests are processed and allows long messages to be processed ahead of shorter ones. Simulation results show that PS-EATS improves network performance in terms of throughput and also marginally reduces the mean packet delay.
