Examining of Reconfiguration and Rerouting Approaches: WDM Networks
Optical Wavelength Division Multiplexing (WDM) networks are high capacity telecommunications networks based on optical technologies and components that provide routing and restoration at wavelength level. High Capacity Optical WDM Networks are either reconfigured or reroute to meet the dynamic traffic demand of the various applications. However, the demand varies with time and infrastructural development. The reconfiguration and rerouting techniques play vital role in this context. It consists in being able to alter the reconfiguration of the network to adjust it to the new traffic demand. Normally it is required to break off partially or totally the traffic to reconfigure a network. In this paper, reconfiguration algorithm has been analyzed and it has also compared with rerouting.
