Discussed

  • Recording: zoom_0.mp4

    • Chat Log: none

  • Project Update - El Alto ExtAPI status

  • Use Cases with potential impacts on NBI for Frankfurt Release 

1) https://lf-onap.atlassian.net/wiki/display/DW/NETWORK+SLICING+in+R6+Frankfurt  - SDC / Modelling Enhancements Impact for External API Framework based on Enhanced Service Information Model for Nested and Shared Services . Need to determine how potential changes in SDC may impact External API. For example the ability to define Service Inputs ( what types supported ) and service level operations and their associated Inputs. The use case also proposes a filter_node with the ability to specify rules for shared service instance selection. Also the use cases uses the ability to nest services via the ServiceProxy, which has an impact on the Service Catalog API, as child service specifications appear as resources.

2) https://lf-onap.atlassian.net/wiki/display/DW/Multi-domain+Optical+Network+Services   - very similar to what CCVPN did for Casablanca in the cross carrier perspective but with a difference in that Interlude looks to be considered directly from NBI , not SO to NBI.  

3) https://lf-onap.atlassian.net/wiki/display/DW/Third-party+Operational+Domain+Manager  - Has some potential overlap with CCVPN and Multi-domain Optical Network Services  in terms of defining and linking partner services. Do we use SpPartner or ServiceProxy. Need for support on POST ServiceSpecification in ExtAPI, the actors to be decided?. Some potential overlap with Service Resolver also, in third party domain interactions and in terms of roles of service decomposition ( inside or outside SDC ). 

4) https://lf-onap.atlassian.net/wiki/display/DW/Service+Resolver – Defines the ability to create Instantiation Rules within a CFS in the selection of RFS to instantiate or in the Service instance selection for a shared Service. We need to decide if this is a POC or a feature within ExtAPI in Frankfurt or is it fulfilled by enhancements to existing components (SDC/SO/A&AI/ExtAPI) via ODM.



  • API Fabric POC presented at Architecture call and a call on a possible hosting of it as a feature within External API Framework Project - API Fabric Proof of Concept Demo Details

  • Discussion of CFS Services , do we need to explicitly mark a ServiceSpecification for CFS as different to any other SDC ServiceSpecification and also the associated Serviceinstances of a CFS v RFS.

Next week:

  • MEF Update @Karthik Sethuraman (Deactivated)

  • Examine TM Forum specs such as TMF 641 v18.5 (e.g., added service type) Should we group services to service type?
