20 minsTAPI Equipment model in a new TAPI branch - 2.1.3Arturo Mayoral
  • Arturo Mayoral recalls that Telefonica is introducing TAPI 2.1.2 in production networks.
  • Given the high need to introduce Inventory Use Cases, the TAPI 2.2 Equipment model has been added in a new development branch v2.1.3, as YANG & Tree files (not in the UML definitions).
  • Two minor changes have been made to maintain backward compatibility:
    • "supporting-access-port" augmentation path (..../tapi-topology:owned-node-edge-point).
    • tapi-common:OBJECT_TYPE based identities (v2.2.0) defined in tapi-equipment model and used in tapi-notifications have been converted to the previous "typedef/enum" format and placed locally in tapi-notification model.

  • All to check the proposal in
45 minsResilience Enhancements
  • Andrea Mazzini presents updated version of otcc2019.AM.004-Resiliency.pptx
  • Nigel Davis : three different concepts, the Domain, the Connection, the C&SC. All these aspects shall be considered for TAPI resilience model.
  • In general, a Switch Control represents resiliency of one connectivity. For further analysis the “restoration domain”, where connections can be inherently restorable.
  • Discussion on “Resiliency Connection”, (see light blue dotted line in below slides) whether is useful to define a Connection in the scope of its Switch Control. It is in line with Core IM, to be checked if useful for TAPI.
