Abstract
This paper addresses the problem of building optical packet switches able to effectively cope with variable length packet traffic, such as IP traffic. Aswit ching architecture equipped with a multistage fiber delay lines based buffer is presented. The aim is to realize a buffer with fine granularity and long delay with an architecture of limited complexity. QoS mechanisms are proposed to support service differentiation by exploiting the wavelength resource and are evaluated by simulation.
