Optical Burst Switching networks are considered as an important candidate for the future transport networks. Many analysis models of OBS node with FDLs have been proposed recently.  In this paper, we propose a novel retrial queueing model at OBS core node architecture SPL - feed-forward. Blocking probability will be calculated based on Markov multi-dimensional models. Numerical solution values from the proposed analysis method are compared with simulation, as well as between these models.

Optical Burst Switching networks are considered as an important candidate for the future transport networks. Many analysis models of OBS node with wavelength conversion and FDLs have been proposed recently.  In this paper, we propose an approximate analytic model at OBS core node architecture SPL – FF (Share-Per-Link - Feed-Forward) for generally distributed arrivals (GI), including Poisson flow, specifically treating IPP distributed interarrival times. Blocking probability will be calculated based on Markov multi-dimensional models and approximation model. Numerical solution values from the proposed analysis method are compared with simulation, as well as between these models.
