2. Outline Wavelengths monitoring solutions Requirements for wavelengths monitoring Lambda Monitor software Deployments of Lambda Monitor Conclusion Future development of LM 2 AICT 2008, Athens, Greece, 8-13 June 2008

3. Motivations Network providers are moving towards the optical networks 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 3 AICT 2008, Athens, Greece, 8-13 June 2008

4. 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 4 AICT 2008, Athens, Greece, 8-13 June 2008

5. 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 5 AICT 2008, Athens, Greece, 8-13 June 2008

6. Requirements for Effective Wavelengths Monitoring Assist and speed up the work of NOC Integrated user-friendly view of wavelengths Easy to identify alarms and localise faults Detailed information for each wavelength (configuration parameters & physical characteristics) Free & open source software 6 AICT 2008, Athens, Greece, 8-13 June 2008

7. Lambda Monitor Overview (1) SNMP-based (read-only polling) Simultaneous monitoring of many wavelengths used by user’s group Real-time notification of current problems occurring in the optical network Integrated view of wavelengths by means of graphical web-based interface Detailed information about the physical characteristics of individual wavelengths 7 AICT 2008, Athens, Greece, 8-13 June 2008

8. Lambda Monitor Overview (2) Implementation –PHP5 –XHTML –CSS –JavaScript Integration with perfSONAR multidomain monitoring system developed in GÉANT2 Released under GNU GPL version 3 8 AICT 2008, Athens, Greece, 8-13 June 2008

9. Lambda Monitor Architecture 9 AICT 2008, Athens, Greece, 8-13 June 2008

10. LM Server Architecture 10 AICT 2008, Athens, Greece, 8-13 June 2008

11. 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 11 AICT 2008, Athens, Greece, 8-13 June 2008 User Interface

12. 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) AICT 2008, Athens, Greece, 8-13 June 2008

13. Lambdas Layer Interface 13 AICT 2008, Athens, Greece, 8-13 June 2008

14. Devices Layer Current status of the interfaces terminating selected wavelength on DWDM devices Possible states of the interfaces: 14 AICT 2008, Athens, Greece, 8-13 June 2008 no alarms on device’s interface warnings on device’s interface critical alarms on device’s interface lack of information about interface (snmp agent is unreachable)

15. Devices Layer Interface 15 AICT 2008, Athens, Greece, 8-13 June 2008

16. Parameters Layer Current values of various monitored parameters on selected device’s interface in the form of graphical tables Detailed information about many parameters which determine and impact the operation of wavelengths 16 AICT 2008, Athens, Greece, 8-13 June 2008

17. Parameters Layer Interface 17 AICT 2008, Athens, Greece, 8-13 June 2008

18. Alarm Browsing Current alarms browser –Enables viewing of alarms that currently occur in the monitored wavelengths Alarms history browser –Presents all the alarms that occurred formerly 18 AICT 2008, Athens, Greece, 8-13 June 2008

19. Alarm Browsing Interfaces Current alarms Alarms history 19 AICT 2008, Athens, Greece, 8-13 June 2008

20. Deployments of LM Software Successfully deployed in two NRENs –PIONIER - in Poland Optical architecture of the network embraces 21 ADVA FSP 3000 devices Monitors 24 of the 10Gbit/s wavelengths used in the PIONIER national backbone –HEAnet - in Ireland Optical architecture of the network consists of 17 ADVA FSP 3000 devices Monitors 14 of the 10Gbit/s point-to-point wavelengths used in the HEAnet national backbone 20 AICT 2008, Athens, Greece, 8-13 June 2008

21. Conclusion Optical network monitoring is very important and requires dedicated monitoring solutions Vendor-specific commercial applications dedicated for operators only on the market LM - open source tool with web-based GUI for both NOCs & users for wavelengths monitoring Fast, exact and user-friendly localisation of faulty wavelength circuits and possible failure reasons Successful tests and deployments Current development of LM under GÉANT2 - JRA4 21 AICT 2008, Athens, Greece, 8-13 June 2008

22. 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 22 AICT 2008, Athens, Greece, 8-13 June 2008
