This area is for analysis of features and one-pagers with a high level LOE from which Epics will be written for the Dublin Release


5G Use Case (Dublin)

Feature Name

LOE

Comments

PNF Plug and Play (Casablanca carry-over items)

Moderate

  • Potential schema changes:
    • PNF
      • Enhance A&AI schema to support PNF inventory, its state, and topology / attributes unique to 5G PNF
      • Using the pnf-id (instead of pnf-name) as the index for PNF into A&AI. Achieve naming indexing consistency between PNFs and VNFs.

      • Migration for previously created PNFs

      • Impacts all API calls/all clients interacting with PNFs
        (alternate solution proposed: A&AI could provide a generic solution to redirect client request URI to a valid URI by translating the client's request to a valid URI)
    • Cloud-region
      • Tracking the Cloud Home Server (CLLI, Cloud ID); and association with the COMPLEX. (existing schema)
PNF Pre-Onboarding & OnboardingModerate
  • Ingest and use 5G NF Packages (CSAR file), PNF Artifacts, Definitions, TOSCA-Metadata - Requires changes to A&AI model loader
  • Run-time catalog update to associate artifacts to a PNF
  • ONAP Run Time Activities: 5G Service Instantiation
 5G Network SlicingModerate

Advanced 5G functionality, for Network Slicing development and early steps in long-lead development.  Service slicing allows advanced steering of services, based on policy, GW loading, and other criteria. 

Impacts:
• A&AI shall store vSSF (Virtual Slice Selection Function) inventory (and associated EMS inventory) and forward it to downstream systems (eg, DCAE, AOTS-M).  (Assumes ONAP will use a vSSF software product and a supporting EMS from some vendor.)
• Radio PNF’s are deployed and configured ( RA, TA’s & cells) and shall be persisted in A&AI.
• A&AI shall also contain inventory of available data centre sites with associated constraints.

Comments

Schedule Optimization with Automated Conflict Avoidance

Test Only

Use existing GET Physical Server (pserver).
Traffic Migration WorkflowEasy
  • Retrieve VNF level ipv4-oam-address.
    generic-vnf.ipv4-oam-address (existing property)
  • Change in the VNF model to introduce an dt-anchor-point capability to vnf of vf. (new property in generic-vnf)
  • Change in the VNF model to introduce an dt-destination-point capability to vnf of vf. (new property in generic-vnf)
  • There is a need to hold pairs of (dt-anchor-point, dt-destination-point) to allow ScaleIn for any VNF in Virtual service. (new properties in generic-vnf)
5G PNF Software UpgradeEasy

SO verifies and queries A&AI for the appropriate PNF entry. (existing functionality).

• A&AI Entry of the PNF is updated with the appropriate software versions. Update Software Version in A&AI
pnf.sw-version property (existing property)


  • No labels
