TAPI RIA 1.2/2.0:
TAPI weeky call
|10 mins||Notes on RIA review||Ramon Casellas|
Ramon Casellas points out that the CSEP is a local class, hence the notification guidelines shall be checked.
Andrea Mazzini shows some consequences of recent agreements on layering.
1: The OLP conceptually belongs to the ROADM / Open Line System, hence the MC CEP is projected on the OLP, to end the MC (protected) Top Connection:
2: The OLP conceptually belongs to the Transceiver/Transponder, hence the OTSiMC CEP is projected on the OLP, to end the OTSiMC (protected) Top Connection:
3: Combination of the two cases above:
Andrea Mazzini notes that for the Asymmetric DSR Connectivity scenario we described a different choice, i.e. the ODU2 CEP is not projected, and the ODU2 Connection is ended conventionally on the supporting ODU4 CEP:
Another scenario foresees a transit DSR ConnectivityService, which is explicitly represented in case there is at least one monitoring point at the layer (slide 74 of otcc2020.AM.001_TAPI_Photonic_Model_Evolution.pptx).
This discussion will continue on next RIA calls.
Resume the discussion on transmission capability
During one of the last RIA calls, Ramon Casellas asked about the need of baseLayerProtocolQualifier attribute of the NEP.
Andrea Mazzini updates some slides on transmission capability to check the attribute, and the preliminary result is that using the multiplexing sequences is enough to describe the capabilities:
Furher analysis of client / UNI port and floating TP models is necessary.
The transmission capability of photonic NEPs shall rely on different parameters, e.g. spectrum, frequency constraints.
Draft of Optical Impairment UML model
Andrea Mazzini presents the updated UML diagram of Photonic Profiles.
