Agenda
• Active Monitoring• Passive Monitoring• Traffic Volume
For Official Use Only
Active Monitoring
• PerfSonar– Network distributed nodes • Geographically distributed w/core nodes• Perform periodic testing• Minimally intrusive• Reveals problems passive testing cannot

Passive Monitoring
• GRNOC SNAPP• Netflow
For Official Use Only
Passive: SNMP
• GRNOC SNAPP– Collection• Interface stats, CPU util, device temperature
– Archiving– Presentation

Passive: Netflow
• Passively sampled (1:1500 packets)– Done at the core-network edge, outgoing– Exported for archive (nfdump)– Currently analyzed with Excel
• (go to Excel)

Applications
• Monitoring reveals:– Health of the N-Wave– Usage patterns of N-Wave– User benefits
• Overall, there is a general “agreement” across the monitoring methods

Total Traffic Transported
• 60-70 TB/day peaks (March 2012):– 1.4 PB in January– 1.5 PB in February– 1.7 PB in March– 0.8 PB in April

Monitoring Futures
• New PerfSonar flows?– Multicast– IPv6
• Netflow– Practical and/or tactical analysis tool, such
as InMon, ManageEngine, SolarWinds ($)– J-Flow (at the Juniper edge?)
