Abstract :
In this paper we propose a technique to support Quality of Service for Bufferless Optical Packet Switches (OPS) equipped with shared Wavelength Converters (WC). The WCs sharing is fully, that is all of the arriving packets share the same pool of WCs. The QoS, expressed in terms of Packet Loss Probability, is differentiated by giving the packets different priorities in accessing both the output wavelengths and the WCs. The effectiveness of the QoS technique is studied by means of a sophisticated analytical model validated by simulation results. The results show that the proposed technique to support QoS allows a good differentiation of the QoS offered to the packets.
