Measurement Point Services

• TL1 MP

–

Provide to execute the TL1 commands on ONS equipments.

• SNMPLite MP

–

Get the status of specific router equipments.

• Correlation MP
• Correlation MP

–

Implement the alarm correlation algorithm that we proposed to simplifies root-cause analysis.

Future Development

• We are going to install perfSONAR-BUOY on all TWAREN GigaPOPs.
• We are going to integrate this alarm correlation system with our production

environment.

• Based on perfSONAR framework, we will continue to develop management system

for SDH or DWDM equipments.
