A lightpath route management system with parallel processing capabilities and a flexible upgradability, allowing new functions to be added to the system without any system program changes, has been designed and implemented for IP-over-CWDM networks with ROADMs. The system can process route management functions composed of some sub applications in parallel in multi machines for high speed performance. In addition, the system was designed to have a flexible upgradability which allows adding new functions to the system, i.e. no changes of the system programs are required when adding the new functions. The system functions are to search possible lightpath routes made by ROADMs with specified switch states, and to output the total optical losses of the routes. The system was implemented and the performance was evaluated. By the system with one management and 3 calculation machines for the parallel processing, the total time to obtain the results for a 5-node IPover-CWDM network was reduced down to 65% of the total time by the system with a single machine without parallel processing. 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.
