Note that TAPI SDK 2.4.1 Last Call, initiated on March 30th, is ending on Friday April 14th. 

TAPI RIA 2.1 delivered - some minor corrections before last call deadline.

See TAPI Call-in Details and Notes for the RIA Review call coordinates.

Warning: in these weeks the RIA editors are changing or deleting some of these sessions.


TAPI weeky call

Preliminary agenda:

  • Continue review Feature priority for TAPI "2.5"
  • Clarification on UUID semantic and usage
  • OAM and Protobuf/gNMI encoding
  • TAPI Hybrid - Equipment and OAM augments to TAPI 2.1.3
    • Photonic OAM vs. Inventory - RIA 1.2 (and 2.1) may make PM metrics as optional in Inventory UCs
  • Model of the internal connectivity matrix of a ROADM
  • Continue the investigation on TAPI-IETF navigation
  • Access to the photonic plug

Andrea Mazzini shows the TR-547-TAPI_ReferenceImplementationAgreement_v1.2.pdf, which now includes the Use Cases of TAPI Hybrid (2.1.4):

  • 0c.1: Mapping Connections to Physical Route – TAPI 2.1.4+

  • 14d: Subscription and Notification of Creation/Deletion of OAM data – TAPI 2.1.4+

  • 17a: OAM Context discovery – TAPI 2.1.4+

  • 17c: Configuration of an OAM profile – TAPI 2.1.4+

  • 17d: Provisioning of an OAM Job – TAPI 2.1.4+

Model of the internal connectivity matrix of a ROADM

All

Andrea Mazzini provides a brief update regarding the state of the discussion.

This slide is shown:

  • Ramon Casellas we need to understand and agree the exact requirements / use cases regarding ROADM/photonic media capability model.
  • Gabriele Galimberti clarifies that a colored ROADM port only supports a single frequency inside the ITU-T grid.
    • Gabriele Galimberti and Ramon Casellas agree that a FlexGrid ROADM has always colorless ports.
    • How many colors? Ramon Casellas we need to define the suitable model for complex constraints, e.g. where a WSS can support only even or only odd (expressed as "n" coordinate) central frequencies, like the light green case in the slide below, while the light blue case is not supported:

  • Gabriele Galimberti highlights that higher OTSi rates are requiring wider slots, e.g. 140 GHz.
  • Gabriele Galimberti takes an action to elaborate which are the more common ROADM characteristics or kind of constraints, possible subject of a capability model.
