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
