Agreed Items & Priority

  • Below the list of the agreed items and related priority.
  • An item is blocking when its resolution is necessary precondition for the delivery.

TAPI 2.1.3 and RIA 1.1

  1. OTU(+ODUCn) CEP/CSEP as single point for OTU/OTSiA ConnectivityService provisioning (solved)
  2. ENNI/INNI Asymmetric service provisioning for multi-domain scenarios, agree UCs (solved)
  3. Alarm / TCA notification (solved - work ongoing on probable cause list)
    1. Subscription
    2. Notification contents
      • Probable Causes / Elementary alarms (e.g. ITU-T cZZZ fault causes), including TCA PM Parameters
  4. OTS and OMS model (solved)
  5. Path Computation Use Cases (blocking)

TAPI 2.3/2.4 and RIA 1.2

  1. MEP/MIP model vs. direct inclusion of OAM parameters in the CEP (solved)
    1. ODU OAM
    2. Photonic OAM
    3. TCA provisioning
  2. Physical impairments (not blocking)
    • OFC is augmenting TAPI Link, others the AbstractStrand.
    • Type of amplifier, fibre attenuation, etc.
  3. Photonic model capability (not blocking)
  4. Lifecycle management of ConnectivityService at every layer, necessary to identify UCs (not blocking)
    • Lifecycle management of single ConnectivityService, necessary to identify UCs
  5. 3R (not blocking)
  6. UNI Client interfaces modelling. DSR/ODU multiplexing over ODU (not blocking)
  7. RESTCONF Response codes for use cases (not blocking)

Discussion items

5 minsAdministrative


Review of TR-547 1.1: Tentative scheduling of 2 hours calls for Sept 20, 22, 23, 24.

  • Invited Ramon, Nigel, Ronald, Pedro, Arturo. Please others interested to contact Andrea.

TAPI weeky call

Preliminary agenda:

15 mins

Any follow up on TIP requirements to ONF/TAPI?


Arturo indicates that the next version of MUST_Optical_Controller_NBI_Requirements_Document_v10_FINAL_VERSION_WEBSITE.pdf will include a backlog of prioritized use cases.

  • The publication is foreseen in one month or so.
60 mins

Update on TAPI 2.3.1 Pre-release


Andrea Mazzini shows the main contents of pull request 515.

  • Discussion on the OAS generation, the related script is becoming complex / circular because:
    • TapiFm imports TapiStreaming
    • TapiStreaming imports all core TAPI modules (tapi-common, tapi-topology, tapi-connectivity, tapi-equipment, tapi-oam, tapi-path-computation,tapi-virtual-network)
  • Agreed to create two new modules, TapiFmNotif and TapiFmStreaming to better decouple TapiFm from both TapiNotification and TapiStreaming.
    • These new modules will include only the fault management augments of notification and stream.
    • Agreed to commit these modifications within pull request 515.

  • Discussion on "feature" and "if-feature".

  • Arturo asks whether there are news on yang2oas tool.
  • A comment has been recently added to TAPI issues 494:
    • "I can see that OAS folder is still present in future r2.3 release for TAPI. Again, if we are publishing something that we know is wrong to our own specifications, sounds like a very bad idea."
    • Agreed to update the release disclaimer as follows:
      • TAPI OpenAPI Specification - TAPI OAS (OpenAPI Specifications) included in this TAPI release (v2.3.1) are an informative part of the TAPI SDK and intended to support TR-547 Use Cases, where a subset of mandatory API is specified.
30 mins

Plan for 2.4 delivery

  • Agreed to add in next week agenda the otcc2020.ND.013_Tapi-NotesOn2.4.pptx contribution.
  • Discussion on OamJob, agreed that it can be applicable to almost all management items, we may explore a more versatile model.
  • Andrea Mazzini informs that in MEF Resource Model Project has been proposed to apply the "if-feature" statement for "RPC support".
    • The team confirmed the decision to remove all RPCs from TAPI 2.4 version.

Resume of “GNPy/CCAMP – TAPI alignment” activity

 Andrea Mazzini presents otcc2021.AM.001_TAPI-GNPy-extensions.pptx

  • Huy Tran points out that new parameters have been defined related to Raman fiber impairments (co-effects) for a more accurate estimation.
    • Explore the model solution, e.g. a new class which augments OTS/OMS links with Raman amplification.
    • The defined data structure is an array of 96 coefficients, each one applicable to one frequency/spectrum value.
  • Recalled that all the proposed "GNPy classes" can be considered as profiles, i.e. common for more instances of links, transceivers, amplifiers, etc.
10 minsLoopback featureRonald

Ronald asks whether the loopback is a generic OAM job type or shall be defined in technology specific modules, e.g. Ethernet loopback, DSR loopback, ODU loopback, etc.

  • Agreed to add this item to next week agenda.
