  • Editors
  • Dave Allan
  • Italo Busi
  • Ben Niven-Jenkins

2
Changes Since Last Version
  • Current version
  • Alignment with MPLS-TP-Framework
  • Alignment with agreements out of Hiroshima
    conference calls
  • ITU-T early review comments addressed

3
Changes Since Last Version/2
  • Key issues resolved
  • Relationship between MEs and the various types of
    transport entities.
  • Genericizing the document for PSTs vs. TCM
  • TCM is simply a degenerate case
  • CV uses MEG ID, not ME ID
  • Clean up of various artifacts of this
  • PST/TCM for PWs clarified
  • Relationship and capabilities of MIPs vs.
    intermediate nodes clarified
  • MIPs only speak when spoken to.
  • Text around out of band return paths added

4
Changes Since Last Version/3
  • Dataplane loopback, lock report, lock indicate
    descriptions added
  • Known implications of p2mp documented
  • Layer/sub-layer aligned with framework draft
  • MPLS-TP is a layer network
  • Some clarification around ordered aggregates and
    Loss Measurement (LM) added
  • Meaningful measurement requires the obvious, it
    is just not actually documented anywhere else
  • MEP/MIP location aligned with framework draft
  • TTL is the MIP addressing scheme in the framework
    draft
  • Both per-node MIP and per-interface MIPs are
    possible
  • Text on measurement and control implications of
    proactive and on demand monitoring added

5
Current Status
  • In last call liaised to ITU-T
  • A few comments received to date, no obvious show
    stoppers
  • Alignment with static pw status
  • Rephrasing of minimum loss probability PHB for
    some OAM flows

6
Next Steps
  • LC Comment resolution
  • Editing to address comments received privately
    and on the TP list
  • Any comments liaised from ITU-T
  • Respin for a 2nd Last Call early April
  • If no more substantial comments received than
    we have gotten to date, declare victory
