Blocking probabilities in WDM switching networks using overflow analysis method

Abstract

Wavelength Division Multiplexed switching networks are considered as an important candidate for the future transport networks. As the size of network increases, conventional methods used in teletraffic theory to model these networks become computationally difficult to handle, as the state space grows exponentially. In this paper, we have applied overflow analysis to model these networks. Our results show that moment analyses using equivalent random theory (ERT) results in accurate approximations for the modeling of WDM switching networks. © 2008 Springer-Verlag.
