Minutes:

• ONAP feedback to ETSI
  • Which version of IFA015 is used when doing the analysis?
    • seems to be v2.5.1, need to confirm with Jessie
• Allotted Resource / Network Slicing
  • Background: service IM call has a discussion on network slicing model, a question is raised on how to model the sharing of a RAN (or other) NSS, allotted resource vs filter based design
  • Is the model targeting sharing the DU, firewall, or a slice?
    • (need create operation/workflow to) reconfigure the DU, and share the slice
    • the operation is for service level
  • How is the onboarding process like?
    • it's preferred that vendor provides the workflow
  • the proposal from Amdocs is to utilise the nested NS/service concept to model the slice sharing
    • https://wiki.onap.org/download/attachments/58230237/ONAP%20network%20slice%20modeling%20-%20for%20modeling%20subcommittee%20v3.3.pptx?version=3&modificationDate=1551338673000&api=v2
  • Borislov: don't think allotted resource is overlapping with the current proposal
    • the intent is not to use allotted resource, but could be combined
    • Gil agrees that nesting is not overlapped with allotted resource, but it's not sufficient, need to describe the sharing of VNFs
    • Borislov: do not think it's necessary to go into the resources, the services could be shared with service level operation (not go into the service)
  • How to model the shared service?
    • Example: how to model the shared DU (DUaaS in the slides)?
  • AP:
    • The main question seems to be: whether need to model the resource level for the slice sharing use case, or how to model the shared service (in detail)
    • It's suggested to give clearer/detailed model for a 5G slice and how to use allotted resource
    • suggest interested people: Borislov, Andrei, Gil, Ben, Thinh and others to have further offline discussions
• VNFD new requirements
  • agreed proposals:
    • affinity/anti-affinity rule for the VduCpd
    • others
  • suggest to move the run time VNF instance model out of this page and could modify the class name to VnfInstance; and to clarify which ONAP component would update the attributes
  • AP:
    • Chuyi would mark the proposals that are mature enough for asking for approval
    • people who are interested please help further review the proposal
    • move the instance model to a seperated page for further discussion
• Meeting time change
  • According to groups.io calendar, following meetings starting from next time will be 1 hour earlier for countries don't use DST yet
