摘要/Abstract

摘要：

Wavelength decomposition approach has been proposed to compute blocking probability (BP) of fixed routing in wavelength-routed optical networks (WRONs) without wavelength conversions. By means of wavelength decomposition, a WRON can be regarded as a set of different layers (colors), in which blocked traffic in one layer is overflowed to another layer. A novel iterative scheme is put forward in case of BP matching used to characterize the overflow traffic from one layer to another in this paper. Furthermore, the analysis of BP based on the improved wavelength decomposition approach is derived and results show that it yields higher calculation accuracy.
