Abstract :
Lightpath reconfiguration management system has been designed and implemented for IP-over-CWDM networks with ROADMs. The system can search possible lightpaths made by ROADMs with specified switch states. The function is based on an equivalent graph method proposed for representing the ROADMs, and can output lightpaths in the network together with the total loss values. The system enables the network administrators to manage the lightpath reconfigurations effectively without errors by avoiding making unlinked lightpaths through routes with higher losses to connect nodes, before the reconfiguration.
