The objective of this study is investigate the performance difference of packet switching architectures working in a synchronous and asynchronous way respectively; in such architectures the packet contention is resolved in the wavelength domain and the used wavelength converters are shared; we investigate on the saving of the number of converters that the sharing technique allows to obtain in the synchronous and asynchronous architectures and compare the obtained results.

Abstract
The objective of this study is investigate the performance difference of packet switching architectures working in a synchronous and asynchronous way respectively; in such architectures the packet contention is resolved in the wavelength domain and the used wavelength converters are shared; we investigate on the saving of the number of converters that the sharing technique allows to obtain in the synchronous and asynchronous architectures and compare the obtained results. These ones show that when a packet loss probability is fixed, in the synchronous case a greater number of converters is saved, in some cases the gain is 40% more than the asynchronous case; furthermore in the asynchronous case a more expensive switching matrix is needed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
