Abstract :
We provide an analysis of end-to-end delay in OBS (optical burst switching) networks and a large deviations approximation. The analysis is based on an exponential approximation of the OBS router blocking time and on the assumption of Poisson arrivals in routers along the path from source to destination. On the other hand, a light load assumption is performed, namely, waiting time is mainly due to the residual life of the output wavelengths and not to buffering.
