Abstract
The development of the Wavelength Switched (WS) Optical Networks (ONet) is introduced to extract the significances of entire Optical Switching (OS) fabrics pertaining to high efficiency and automation. However the selective switches of wavelength (SW) indicates the prior switching elements subjected with Reconfigurable Optical Add/Drop Multiplexers (ROADM) frameworks exhibiting the different color-less, direction-less and also with contention-less (Col-Dl-Conl) switching features. With the implementation of the Col-Dl-Conl based ROADM, the WSw ONet nodes will be asymmetrical subjected to its switching abilities. In the process of Quality of Service (QoS) enhancement, choosing switching abilities plays a major role subjected to number of ports (Np) and the asymmetry depends over SSw port size. This paper introduces an efficient model of ROADM switching connectivity (SwC) to achieve Qos for given Np. The performance analysis is performed by considering QoS and found that it depends on SwC.
