Investigation of rerouting system in Optical Network

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. Many parameters have to be taken into account to find out a good solution, and many metrics can be used in order to measure the quality of a solution. In this work a 5-Node network has been taken and through simulation different parameters (Such as per lightpath report: Node routes, per lightpath report: link routes, lightpath report: distances, per lightpath report: carried traffic and per lightpath report: wavelength utilization) has been examined.
