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

The Right

In many-server systems it is crucial to staff the right number of servers so that targeted service levels are met. These staffing problems typically lead to constraint satisfaction problems that are difficult to solve. During the last decade, a powerful many-server asymptotic theory has been developed to solve such problems and optimal staffing rules are known to obey the square-root staffing principle. In this paper we develop many-server asymptotics in the so-called quality and efficiency driven regime, and present refinements to many-server asymptotics and square-root staffing for a Markovian queueing model with admission control and retrials.
