• Alignment with agreements out of Hiroshima
  conference calls
• ITU-T early review comments addressed

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

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

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

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
