R6 / R7

ReadtheDocs

Read the Docs

  • ACTION: Update ReadtheDocs https://git.onap.org/integration/tree/docs - Jira under Integration - invite team for review - invite PTL (Morgan R.) -Gerrit PTL submission +1 from reviewers. committer/Morgan +2 (someone in Integration project will do the Merge)
  • New project → Repo → DOC directory (RST) in that Repo Andreas Geißler  → Signoff for R6 May 2020; M0 for R7. If we are approved by TSC as a new project → create a new Repo

R7 Guilin

Content / requirements

Requests for R7 Requirements are up.

Guilin release - functional requirements proposed list

Timeline -  Sign-off for R6 is May 7. Historically M0 kickoff for R7 is May 7th

PROPOSALS FOR R7 GUILIN FOR WHAT WE PLAN TO BE DOING IN R7:

  1. R7 Project Proposal (identify PTL, Project proposal, setup repo)
  2. =STEP 0= Initial Database Setup
  3. =STEP 0= (Design time), (Setup DB) Yang Model development ORAN specification Yang Model in line with 3GPP. SQL structure.
  4. =STEP 0= Schema design & API
  5. =STEP 1= CMnotify generated by RanSIM extended (final standard format).
  6. =STEP 1= VES generation, Nokia Simulate DU → simulate VES CMNotify message.
  7. =STEP 1-6= CMNotify (Nokia) Integration Step 2,3,4 with SON work Step 1,5,6

  • STEP 4: DCAE PUBLISHES onto DMaaP - Nokia (R7)  REQ-327 - Getting issue details... STATUS
  • STEP 5: CCSDK (Controller) LISTENS to DMaaP - Sandeep Shah  (R6 Done) → (R7) CCSDK-2392 - Getting issue details... STATUS
  • STEP 5a: RTCDB (stand-alone component) LISTENS to DMaaP (R7 new)
  • STEP 6: RTCfgDB UPDATES DB with info - Sandeep Shah / Techmahindra (R6 Done) → (R7)

A&AI FLOWS:

STEP 1...6: Initial A&AI setup of DB (the setup of the DB with the initial set of all xNFs a "getall")

STEP 1...6: A&AI Update (e.g. a new xNF is added or deleted)

R7 Wiki PageConfiguration & Persistency Service R7

For Honolulu REQ-Jira (copied from REQ-322)

Configuration & Persistency Service: (Code Impact)

  • Leverage (Maria DB) as mS CPS to support the logical data model/devise model.
  • Build the data model for real time presentation of 5G network and store the network element data to the CPS database
  • Initialize CPS Database including A&AI setup, database schema setup, with initial values.
  • Receive Config information updates from SDN-R via Netconf and with VES notification.
  • Support all vendor specific Configuration Information Model ( CIM/Yang)
  • Impact: Code Impact
  • Companies Supporting: Ericsson, Nokia, AT&T, WiPro
  • Number Developers/Testers: 7

Email Swami:

PFB comment from TSC for the OOF SON requirement. With reference to resource commitment:

  • Policy: Pam - Shall I indicate AT&T shall cover it, while we subsequently discuss what all enhancements we can do in Guilin timeframe, as well as check reg. some of the aspects where you indicated use case team should contribute (e.g., separate Drools file, which would have to be done by Wipro).
  • SDN-R/CCSDK: Sandeep - Shall I indicate IBM?
  • CPS: Shankar/Ben - Given the Guilin release timeframe, I think we have to go for the simplest option (1) and indicate no impact to CPS, where we only change the yang models, and SDN-R continues to do the mapping. modify CCSDK solution to extend interfaces (OOF/SON/PCI Team updates). R7 Solution of C&PS (evolution "ConfigDB" = C&PS) Hard code information
  • R6 C&PS 1.0 = CCSDK/SDNC solution / R7 C&PS 1.1 = CCSDK/SDNC evolution+MDCPS PoC / R8 C&PS 2.0 = Standalone component

Model Driven C&PS PoC

Proposal (by Ciaran Johnston et al) as a step of Model Driven ONAP, Model Driven CPS. See slides in the Project Proposal page, and also in the R7 CPS Wiki. 

Question: Graph DB? Answer: type of data from xNF to be hierarchical which would fit in a Graph DB. doesn't have to be that though. Likely to be one or more underlying database technologies. time series.

Question: Model driven CPS, uS on-boarding in CCSDK. If you plan to do modeling work in R7, consensus from Arch S/C. Answer: would need CPS team, modeling, Arch S/C to be aligned. Want something that can be demonstrated/delivered in R7.

Question: Are there dependencies on platform components? Answer: TBD

- Looking at internal sourcing to get development resources. Sync with johnsont


  - Status ready to cut code off of x CC-SDK repo. Ongoing analysis. Resourcing Toine has started, 2 new people will be added in August 1, 2020. Present to Architecture S/C before end of July. Engaged Modeling S/C. Visible Yang modeled to be consumed in ONAP. Modeling work will happen in

Time Series management

TSDB

  • Choice of IT DB (feeds in). Choice of DB to best fit to the use case. Implement TSDB in PostGres or MariaDB, SQL extensions for TS analysis. Issue is how good is the performance. Not as good as specialized Influx DB. Postgres 10 direct it to store TS DB similar to influx. Database derived from postgres. Timescale DB derived from postres.
  • https://en.wikipedia.org/wiki/Master_data_management
  • PM Data how to aggregate avg. performance over time. for ML training data or ML model input.
  • Ted Johnson MCX app, RT RIC - Nokia to install influx DB to manage TS.

Question: Are there dependencies on platform components? Answer: TBD

Wiki: in progress

Former user (Deleted) - Listen to Recording from  

Question from s.silvius  - State Management was interesting could we get the basic arch picture and def lines of description? Having references e.g. to A&AI is better solution than planned CPS to copy inventory data ANSWER: We are going to prepare a public page and share with you.

Network Slicing & C&PS

CPS w.r.t. Network Slicing: (Swami)

For the Network Slicing use case, we are still working out the details w.r.to RAN slicing, and are also in discussion with O-RAN folks. We expect it to take 1-2 weeks to conclude. Once it is fairly clear, we should discuss reg. the CPS impacts for Guilin.

For now, we have created Jira SDNC-1199 for the CPS requirements for this use case. As of now, we may not have resources to commit for implementing the updates in CPS (but still checking), in this scenario, there are 2 alternatives:

  1. The impacts to CPS (which I expect to be persistence & retrieval of some basic RAN slice config related data) can be handled by existing CPS committed resource

(or)

  1. The details are stored ‘locally’ in a DB in SDN-C for example. In the next release, it is moved to CPS.

(EMAIL) from Swami  

For Network Slicing use case, for RAN Slicing, we will be needing a minimal set of information elements for initial RAN configuration and network slice-subnet specific configuration. Our current R7 GUILIN proposal is to extend ConfigDB with the required aspects for Guilin release, and once CPS takes off as an official ONAP project in HOLULU R8 H-release, the work can be taken over into CPS.

Software Status

Release R8

  • CPS Release tasks:  Getting issues...
    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) ?

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 CPS-TBDMT 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

DB Schema

Software Status

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.
  • Former user (Deleted) 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  CPS-168 - Getting issue details... STATUS
  • The queries can be subtasks of a single query user story assuming all queries need the same basic CPS Cor and xNF Proxy functionality
