Paper Abstract

The use of optical buffering (OB) and wavelength converters (WC) is recognized as essential for reducing the complexity of optical packet switches (OPS). The object of this study is to investigate the performances of optical packet switches in which the wavelength converters are shared per input channel (SPIC) and optical buffering are partially shared working in unicast and multicast ways through analyzing a traffic model. We compare the packet loss probability of the unicast case and the multicast case, as the number of converters and depth of buffering in them are fixed. We also analysis of the improved performance by increase the number of wavelength in each channel.
