  2. Overview • Backgrounds and detailed requirements of new hitless and temporal path segment monitoring based on section 3.8 of OAM framework • Elaborates differences from Sub Path Maintenance Element (SPME) • Relevance for OAM tools: • Intended for on-demand (temporal) OAM functions. • In particular, mandatory for performance monitoring (LM and DM) to localize a degraded point in a transport path • Further considerations on • Single- vs Multi-level monitoring • Independency from pro-active OAM functions • Flexibility in setting of segment • Applicable in both per-node and per-interface model

  3. Updates from ver2 • New co-authors • Mr. Manuel Paul (Deutsche Telekom) • Mr. Satoshi Ueno(NTT Communications) • Reflected minor comments in off-line discussion

  4. Changes to be reflected in the next update (-04) • Refinedrequirements on hitless and temporal segment monitoring • Considering how to handle the issue of TTL distance in such as protection events shown in section 3.8 of OAM framework draft (temporarily invalidating OAM information) • Add note that this draft will need IETF consensus

  5. Next steps • Solicit further comments on ver.3 • Update the draft very shortly • Invite further comments on ver.4 • Ask for WG poll
