• Researchers are increasingly using dedicated optical paths for creating high speed network connections
• Optical paths may span over multiple administrative domains and different vendors
• Open source is a key for research purposes

Wavelengths Monitoring Solutions (1)
• Only few monitoring tools available for wavelengths monitoring
• Vendors of optical systems have created vendor-specific tools – such as for example– ADVA FSP Management Suite
• FSP Element Manager • FSP Network Manager • FSP Network Planner
– Alcatel• Alcatel 1320 Craft Terminal • Alcatel 1352 Compact Manager

Wavelengths Monitoring Solutions (2)
• Biggest limitations and disadvantages in the mentioned before vendor-specific tools
– Lack of free and open source software
– Functionality dedicated for network operators only (not for wavelengths’ end-users)
– Lack of integration for multiple vendors and various equipment platforms

• Hierarchical user interface – one simple view for complex network and top-down approach to see more detailed information if needed
• Three levels of GUI (called layers)
– Lambdas layer
– Devices layer
– Parameters layer
• Current and historical alarms browsers

User Interface
![Page 12: Effective and Open System for Wavelengths Monitoring](https://reader035.vdocuments.site/reader035/viewer/2022062806/56814f7c550346895dbd2bb7/html5/thumbnails/12.jpg)
• Current status of monitored wavelengths (end-to-end view)
• Possible state of the wavelengths:
Lambdas Layer
OK state - lambda circuit works OK without any alarms
Warning state - occurs when some warning type alarms are present in the lambda circuit
Critical state - occurs when any of critical alarms appeared in lambda circuit
12
Unknown state – lack of information about lambda circuit (snmp agent unreachable)

Future Development of LM
• Main propositions for future LM development in the Emanics project
– Parameters archiving (historical values of monitored parameters in the form of charts)
– Monitoring and notification of configured thresholds exceeding
– Mail notification of current alarms occurring in monitored wavelengths
– Full system documentation & install packages for various distributions with user guide
