Owner namespace

• Owner assigned indexes
• Owner Name
• Owner instance Index
• Distributed naming
• Same identifier for a measure on IPPM proxies
• For aggregated measure and setup
• Interdomain unambiguous naming

8
IPPM Metrics Registry

• IPPM Metrics Registry
• IPPM metrics
• RFC2678-2681
• RFC3148, RFC3357
• RFC3393 RFC3432
• Template for future IPPM metrics
• Distributed metric measure index

9
Measures sharing control VACM

• VACM Access list
• Who, from, session,action, object, instance
• Which sub tree an user can access ?
• Usage
• Aggregation
• Reporting
• Sharing results
• Measurement peering

10
Aggregation IppmAggrTable

• Aggregation of
• Network measures
• Aggregated measures
• Sharing measures
• Name spaces
• Fast reporting
• Maintenance
• Troubleshooting

11
SLA monitoring ippmReportTable

• Backgroup monitoring
• Metrics thresholds
• UpAndDown lt gt in out
• Exceeded Duration
• Errored periods
• Report
• Locally or remotely
• On event
• On Measure cycles

12
Interdomain measure ITU O.iptest

• Packet Signature
• Any Type-P IP, IPv6
• Sqce , Timestamp
• 3 optional IE
• CRC32,
• timestamp bar,
• Interdomain
• Interdomain IE
• IPPM Reporting MIB
• OwnerID MeasureID
• Carrier class results

13
Intra/inter domain correlation issues

• Need
• Correlate intra and interdomain results
• Report
• One solution
• Concatenation of intra domain measure
• Decomposition of e2e inter domain measure
• Missing
• Standard spatial metrics

Conclusion

• Measure sharing security with SNMPv3/VACM
• Measurement peering with IPPM Proxies
• Statistical e2e interdomain QoS monitoring
• True e2e interdomain QoS monitoring with O.iptest
• Standardization of spatial metrics is required
• Concatenation of e2e intra domain measures
• Correlation of intra and interdomain e2e measures
