  Jira
  server ONAP JIRA jqlQuery filter=12477 count true serverId 425b2b0a-557c-3c0c-b515-579789cceedb

  
  Propose to be closed for new features/requirement. Already committed to:
  
  • E2E Network Slicing. Sync up with PTL
  • Son (Stretch)
  • Temporal DB (no REQ yet?)

E2E Network Slicing

• Presentation from Tony Finnerty on E2E NW  integration with CPS (Draw.io, PPT)
• E2E Needs 2 sets of data 
  1. Slicing specific model. Fred Feisullin has a diagram describing that data S9tored in CPS)
  2. Needs some CM data but not depending on notifications (available through xNF Proxy)
• This mean the 'current' model provided by Sandeep Shah needs to be split?
• Data will be pre-loaded using 'config' files or something similar by xNF Proxy
•  Resourcing
  • xNF Proxy not resourced (need to explore, ask on onap discuss, swami will consider too)
  • DES-Like Data model transformers will be resourced by E2E Team
• CPS engage Slice Teams (Mon slicing weekly) ?

M2 Milestones

Swami, planning next

Support for Vertical Industry

• Benjamin Cheung  recommends to view Use Case Realization Call: Jan 14, 2020
  
  • industry using a 'private radio network' which ONAP could manage
  • 'tenant' is the owner of the 'private' network
  • CPS could contact Cheng Huangabout this use case
  • need to decide where A&AI stops and CPS begins...

E2E Network Slicing

• Discuss current API ie. what data and queries are required
  1. CPS Interface
  2. xNfProxy interface (for data owned by xNfProxy)
  3. API Mapping DES-Like interface  (query templates)
     1. Where to host code? temporary in CPS Repo
     2. proposal: CPS APIs  and API Mapper Service
     3. query/template will be link to a schema-set(id)
     4. network call information about multiple xNF instances, this needs to be addressed
        For Honolulu it is preferred to keep 1 singel instance?!
     5. Even if 1 anchor (with agreed id) we have add that to interfaces
• Will continue in Monday E2E Network Slicing Meeting: https://lists.onap.org/g/onap-meetings/viewevent?repeatid=31927&eventid=970358&calstart=2021-01-18

Introduction New team Member:  Hanif Kukkalli

DB Schema

• latest DB schema published on the Developer Landing Page

Software Status

• KanBan board: https://jira.onap.org/secure/RapidBoard.jspa?rapidView=228
• Recently completed & ongoing: https://gerrit.onap.org/r/q/project:cps
• Issues & Decisions - Issues decisions and assumptions

M2 Milestones

• CPS R8 Release Planning
• Deployment in ONAP and related requirements such as documentation were agreed to be a major risk/unknown impact for this new team. Task investigating what is required need to be prioritized
• Benjamin Cheung kindly agreed to present detail about  ONAP documentation/process in next week meeting 
• Toine Siebelink will works with swam to identify E2E Network Slicing related user stories such as those required for the new models mentioned below.
• Bruno Sakoto will work with Toine to define a list of user stories for the Temporal DB aspects
• One all user stories have been identified a team meeting is required to agree what is feasible in the Honolulu time frame

Architecture Update

• Short Presentation by Tony Finnerty  CPS-MVP-Component-Responsibility.pptx
  • CPS consist of 3 main components
    1. DB   Generic Yang data store
    2. CPS (core) CRUD access control, ownership
    3. xNF Proxy. Cache for CM data
  • Additional we will have  
    1. Model-Transform (DES Like modified view)
  • Suggested name for API Mapp/DES like transformer: TemplateBasedDataModelTransformer
  • TemplateBasedDataModelTransformer will be separate service from CPS and XNF Proxy. for reason of scalability and segregation of responsibilities

E2E Network Slicing Use Case

• Sandeep Shah has presented an overview 'new model' that will represent the 'external; data' not captured in the RAN Network model. Thing like Near RTRIC mapping.:
  
  • 4 models are proposed, all of them contain at least E2E NW Slicing data and some also contain SON data.
  • Approx. 15-20 queries are being proposed. However is is expected these can all be executed using the same core CPS and xNF Proxy functionality:
    • qualified cpsPath query (get). assuming each model is stored/associated with its own Anchor. Or the models are tied together using an overarching parent model (yang module). To be discussed!
• Swaminathan Seetharaman and Toine Siebelinkagreed to track each model as a user story under 

  Jira
  server ONAP JIRA serverId 425b2b0a-557c-3c0c-b515-579789cceedb key CPS-168

• The queries can be subtasks of a single query user story assuming all queries need the same basic CPS Cor and xNF Proxy functionality

Breakdown of user stories discussion:

• New function: retrieve DataNode WITHOUT children, do we need this?
• Do we need separate user stories for:
  • Store & retrieve (keyed) Lists
  • Store & retrieve leaves (standard attributes)
  • Store & retrieve leafLists
• Alternatively work on E2E Slicing models and handle 'bugs' for what is not workingworking
  Team agreed to handle functionality through bugs as issues with E2E Models and Data samples arise
  Tests wil need to be added for specific functionality like stores leaves, leafLists etc
• Update functionality (no epic or user stories yet!)
  • E2E network slicing only required CSP updates (no forwarding of updates to NF required as this is done elsewhere already)
  Update user stories
  • What types of updates do we need (what is achievable in Honolulu)  
    Ahila suggested to use Yang Patch payload, see  https://tools.ietf.org/html/rfc8072#page-5
    Will try to get more details by next week. 

(TBD) Modeling Discussion
