  2. Summary • Result aggregation • SLA monitoring • Standardization status • Data model & Architecture of the MIB • Namespace & IPPM Metrics Registry • Measures sharing and control • Interdomain with IPPM MIB/ITU O.Iptest • Intra/inter domain correlation issues • Conclusion Workshop on End-to-End Quality of Service. What is it? How do we get it?

  3. Acronyms: VACM: View Access-based Control Model MP: measurement point or probe WG: working group. Foo, Bar: names of management applications Abbreviations: E2e: End to end; QoS: Quality of Service rootX: Domain X network measures manager Net: ippmNetMeasureTable Aggr: ippmAggrMeasureTable Rpt: ippmReportSetupTable IE: information element Abbreviation & Acronyms Workshop on End-to-End Quality of Service.

  4. Standardization status • IETF • IPPM Reporting MIB • Presented during 51st IETF • WG Item after 53rd IETF • Current version 04 • IPPM metrics Registry • Requested by RMON WG • WG last call done • ITU • O.Iptest • SG4 draft of IP test packet Workshop on End-to-End Quality of Service. What is it? How do we get it?

  12. Mgmt Net.Bar.5.6 Net.Bar.5.6 Network IPPM MIB IPPM MIB Domain X Domain Y Bar.5 IP Test Packet • Test Packet: Type-P + data + O.Iptest Signature • Example: • Type-P source A: (ip.udp,19.0.0.1 10000) • Type-P Destination G: (ip.udp, 12.0.0.1 100) • Owner: Bar ; Owner Measure ID: 5 B F A E G C Internal control A-G: probes ; Setup O.iptest packet Report 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 Workshop on End-to-End Quality of Service.

  13. Need: Correlate intra and interdomain results; Report; One solution: Concatenation of intra domain measure Decomposition of e2e inter domain measure Missing Standard spatial metrics I H J B F A E C G Intra/inter domain correlation issues Interdomain: Net.Bar.5.6(AG) Intradomain: Net.rootX.9.6(AB) Net.rootZ.7.6(HJ) Net.rootY.5.6(FG) Concatenation: AG=AB + HJ +FG Spatial.Foo.18.?(AG) =rootX.9 +rootY.5 +rootZ.13 Decomposition: AJ = AG - FG Spatial.Foo.19.?(AJ) =Net.Bar.5.6 - Net.rootY.5.6 Management Domain Z Network Domain Y Domain X A-G: probes ; Test packets ; O.iptest packet Workshop on End-to-End Quality of Service.

  14. 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 Workshop on End-to-End Quality of Service.
