• Photonic LTP Model: https://wiki.opennetworking.org/download/attachments/259719184/TAPI%20Base%20Photonic%20Model%20v5.3.pptx?api=v2
  • 
  • Cardinalites: r, s, n, N
    • Need clarification
  • OMS link between the transponder and ROADM
    • Stay with label of OMS link at the moment, don't create additional label
  • MEP: clarified the up/down, the up/down semantic is consistent with Ethernet
  • OPM measure both the power going out and the power coming in, so no up/down,
  • OTSi and NMC
    • In ITU-T definition, OTSi is the optical signal, NMC is the media channel, both have the same starting point and the same ending point.
• Bernd's mapping of the object classes:

  • 
  • No need to model the NMCA Pool and SMCA Pool, so no mapping
• Power measurement: Not the total of the assembly, but the power of each individual NMC/OTSi memberPH

• TAPI Base Photonic Model v5.3 https://wiki.opennetworking.org/download/attachments/259719184/TAPI%20Base%20Photonic%20Model%20v5.3.pptx?api=v2
  • LayerProtocolQualifier of ServiceInterfacePoint, NodeEdgePoint, ConnectionEndPoint
• Use cases: https://wiki.opennetworking.org/download/attachments/259719184/TAPI%20OTDN%20Scenarios.pptx?api=v2
  • With OLS controller
  • ODTN Use Case-1: OLS topology not exposed on ONOS NBI
    • Use 2 requests: one for the photonic, one for the DSR
  • ODTN Use Case-1b: Single "User" Connectivity Request
  • 1)One NMS per NMCA
  • 1.1) Two NMCs per NMCA, on same Add/Drop Port
  • 1.2) Two NMCs per NMCA, on different Add/Drop Ports
  • 1.3) Two NMCs per NMCA, two NMCAs, all on different Add/Drop ports
  • 1.4) Same as 1.3, but mapped two SMCs on same Degree Port
  • 2) SMCs reorganized in transit ROADM:
    • Not to include this case
• Guard band
  • Agreed no need to explicitly expose/model the guard band in TAPI at the moment
