Abstract

In recent trends, many bandwidth applications require multicast services for efficiency matters. Typical multicast applications include video lectures, e-commerce, multiperson conferences and so on. The multicast can be supported more efficiently in optional domain by utilizing the inherent light splitting capability of optical switches than copying data in electronic domain. Wavelength division multiplexing (WDM) technique emerges as a promising solution to meet the rapidly growing demands on bandwidth in present communication networks, supporting multicast. In this paper, the multicast connection capacity of WDM switching networks without wavelength conversion is analysed. Further, the capacity of multistage WDM multicast switching networks and the advantages of multistage switching networks are discussed.
