| Summary: | Lightpath route management system has been designed and implemented for IP-over-CWDM networks with ROADMs. The system can search possible lightpath routes made by ROADMs with specified switch states. The function is based on a ROADM graph proposed for representing the ROADMs, and can output lightpath routes usable in the network together with the total optical loss values. The losses can be calculated by only 3 basic values for the ROADM and one value for the fiber link in the network. The experimental results clarified that the difference was within 1 dB between measured and calculated values. The system enables the network administrators to manage the light path reconfigurations effectively without errors by avoiding making unlinked light paths through routes with higher losses to connect nodes, before the reconfiguration. |
