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

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

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

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

Lambda Monitor Overview (2)

• Implementation– PHP5– XHTML– CSS– JavaScript

• Integration with perfSONAR multidomain monitoring system developed in GÉANT2

• Released under GNU GPL version 3

Lambda Monitor Architecture

LM Server Architecture

• 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

• 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

Unknown state – lack of information about lambda circuit (snmp agent unreachable)

Lambdas Layer Interface

Devices Layer

• Current status of the interfaces terminating selected wavelength on DWDM devices

• Possible states of the interfaces:

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)

Devices Layer Interface

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

Parameters Layer Interface

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

Alarm Browsing Interfaces

Current alarms

Alarms history

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

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 - JRA421AICT 2008, Athens, Greece, 8-13 June 2008

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
