  1. Framework for Metric Composition + Spatial Composition of Metrics Al Morton + many others July 24, 2007

  3. Complete/Sub-Path (or Concatenation in Space) Aggregation in Time (12x5min stats ->1hr) Aggregat. in Space Types of Composition

  4. Status of Framework 04 • Six Phases of a Project1.Wild Enthusiasm2.Total Confusion3.Disillusionment <= We seem to be here4.Search for the Guilty (WGLC)5.Punishment of the Innocent (Directorate Rvw)6.Promotion of the Non-participants (AUTH48) • This is an important problem to solve • IP-layer efforts are leading the performance standards community on this topic

  5. ETY Maintenance Entity Point Maintenance Intermediate Point Composition at MEF? MEN A (SP) MEN B (Op) CustomerEqmt CustomerEqmt MEN A NID E-NNI MEN A NID MEN B NID SW 3 SW 4 SW 5 SW 6 Notes: • Switches 3 and 6 have some UNI functionality. An open question is how much is performed in the NID and how much in the switch, but we won’t focus on that now • There may be multiple switches between 3 and 4, and between 5 and 6 • MEN A’s NID on the right is optional (more later) • It is debatable whether MIP/MEPs are on the right, left, or either side within a given device. Specific locations to be addressed later 1 2 3 4 5 6 7 8 9 ETH

  6. Status of Framework 04 • This was a maintenance update • Next Steps • Consider this text sufficiently stable? • If not, Convince more folks to Read and Comment

  7. Status: Spatial Composition 04 • Revisions to Outline and new Metric (5) • Type-P-Finite-One-way-Delay-Poisson/Periodic • Type-P-Finite-Composite-One-way-Delay-Mean • Type-P-Finite-Composite-One-way-Delay-Minimum • Simplified some Metric names: • Type-P-One-way-ipdv-refmin-Mean = MeanIPDVRefMin • became • Type-P-One-way-pdv-refmin-Mean = MeanPDV • NOW: Need Volunteers to read and comment
