Discussion Items


Record the meeting

London Dec. 4 - 8, 2017 meeting (Invited by ITU-T)

2018 Face-to-Face meeting proposal

  • Proposed meetings: Face-to-Face Meetings
    • 3 meetings have been planned.
    • The dates of these 3 meeting are pretty firm now because they are selected so to avoid conflict with other SDO meetings.
 Layer examplesXiang/Kam
 Ethernet OAM in G.8052.1 and IEEE 802Kam
  • G.8052.1 Ethernet OAM UML & YANG
    • G.8052 v2.04 OAM
      • The OAM details are in the MepSource/Sink/Bidirectional, ETH_TTPSource/Sink/Birectional, ETH_CTPSource/Sink/Bidirectional, MeasurementJobControl classes
        • These classes will be pruned for the non OAM artifacts
  • IEEE 802 YANG
    • CFM
      • uml-lite-cfm:
          • IEEE YANG models
            • Links of the latest drafts are to be provided
  • Touch point of the G.8052.1 and IEEE OAM models
    • The G.8052.1 Mep and ETH TP are the touch point objects to the IEEE OAM model, in particular to the IEEE MEP and Component classes
    • Three possible approaches for the touch point mechanism
      1. Spec approach: The G.8052.1 Mep and ETH TTP/CTP decorate the IEEE MEP and Component
      2. Subclassing approach: The G.8052.1 Mep and ETH TTP/CTP are subclassed from IEEE MEP and Component
      3. Reference approach: The G.8052.1 Mep and ETH TTP/CTP point to the IEEE MEP and Component for the needed properties
  • Issues occurring during "re-engineering" of IEEE YANG modules to UML
    • YANG module name has number directly following a character: ieee802-dot1ag-cfm
      The tool inserts a "-" between characters and numbers: ieee-802-dot1ag-cfm
    • IEEE and IETF YANG modules use the same container name with different properties in augments
      Scott mentioned that this is already known and will be changed
    • Mapping tool maps all object classes into YANG groupings and inserts these groupings via "uses" into container or lists
      The "hand crafted" YANG modules add the properties directly via "leaf"
