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
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!
The goal for MVP is to deploy alternative 2 here (CPS core and NXF-REST proxy in one service) with OOM. With a possible inclusion of Temporal DB RETS interface when available (alternative 3)
Misc
The schedule for the LFN Developer & Testing Forum is now live here. Tony Finnerty& Toine Siebelink will be presenting CPS-NF-Proxy MVP on Thursday Toine Siebelink will be presenting on using Spock and Groovy for unit test
E2E Slicing team will provide data sample and query information when ready

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 working 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)
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.

Toine Siebelink has shown overview of possible query and update scenarios. CPS Team needs input from E2E NW for the scenarios required by them with data examples and possibly SQL statements etc, Swaminathan Seetharaman will propose follow up meeting for Tuesday examples and data can hopefully be provided earlier

Both methods use E2E Slicing specific model through CPS-Core. This means NF-Proxy interface not required (for E2E Slicing)
#2 requires new query: CPS-235: Overview of (early) CPS Query query #3 This will be handled as a 'bug' as code freeze date is to close #2 also requires a 'with children' option on the query, also to be handled as a 'bug'
#21 is a simple 'get' by xpath with children which is already supported by CPS Core. Latest Model & Data sample need to be confirmed, Toine Siebelink suspect latest data.txt sample provided in

TBDMP Integration as submodule to be discussed with Claudio David Gasparini TBDMP Sub repo in progress, split in separate commits: structure, code, tests. Need to think abut structure and split the PoC in required modules. E2E Slicign team will drive required tasks, track in Jira et with support from CPS Team. krishna moorthy will handle deployment? For now as uService as subschart in CPS but TBDMT should remain independent of CPS! Claudio David Gasparini can support with OOM integration
Explore Yang-Patch, E2E. Sandeep Shahshowed a basic example of a a Yang Patch with an 'edit' operation:
Patches are transactional, if one fails, all fail (and rollback of already completed steps) Patches are NOT used for adding elements to a Yang List

E2E Network Slicing Use Case
CPS APIsAPI methods #2 and #21 will be prioritized for H release
Build issues. Claudio David Gaspariniexplained we need to raise a ticket on LNF and create a ci-management change.
OOM integration, we are probably too late for this but krishna moorthywill start process anyway with support from Bruno Sakotoand Claudio David Gasparini OOM integration of TBDMT needs to remain independent of OOM integration of CPS! As a fall back option TBDMT can be manually added to an ONAP deployment for demo or a local deployment an be used.
Need to support at least 2 CPS endpoints.. Get and 'Query'. The query endpoint is ' <server>/cps/api/v1/dataspaces/dataspace/anchors/anchor/nodes/query Demo available in this video. Krishna wil handle this requirement as a 'bug' after M3
Swaminathan Seetharaman will create new REQ's for E2E Slicing and SON PIC (scope to be still discussed internally)
Future of TBDMT, not clear is nice as part of CPS but will require additional resourcing as much work still needed like integration, conform to CPS-Core quality standards etc. Swaminathan Seetharamanand krishna moorthywill prepare slides to follow up this discussion next week with a view to take it to Arch. Committee.
E2E Network Slicing Use Case
CPS APIs How to continue? Proposed to split according to 'operation' 2 teams of 2. Toine Siebelinkwill create Jira's to track this work. If needed CPS team can meet E2E team middle of next week for further clarification. see
OOM blocked, RC0 postponed by 1 week CPS team just waiting on OOM to merge (gating jobs are passing) CPS-290 more scenarios of 500 error to be discussed
Presentation on E2E slicing Check Andy MAYER (ATT) Ruhal Tyagi (Ericsson)
'Home' for TBDMT for review with ArchCom Template need to be aware of Model/Version Versioning could be part of ID Template should be applicable to range of versions Preferred by Team: TBDMT stay in CPS. Main concern is Resourcing. Swami will add slide with options and Pros & Cons and review slide again next week
Owner of slicing 'config' data has to be the 'use-case' (not the TBDMT)
Process for dopping back Toine Siebelink will document a proposed WoW for bugs on confluence with help from team In general all bugs should eb fixed on main branch and dropped back to previous release. Consider API changes, user story Acceptance Criteria etc. If there is no API/behavior impact and it didn't break acceptance criteria then it could be an 'enhancement'. Claudio David Gasparini will prepare for discussion on backward (in)compatible updates next week
AOB
Agreed to change meeting duration back to 1h starting next week
Please note DST has started in US, This will affect attendees in zones with different DST rules
so it can be postponed to Istanbul (no need to dropback to H) - Security Hotspot, needs to be flagged as False Positive. Amy Zwarico will follow up on this
Only impacts CPS (no other ONAP components) so now classified as a 'Specification'
SDNC (integration) Using RESTCONF ODL Interface Test Only impacts
Claudio David Gasparini suggested to use Java-API client? Would be significant arch. change! Take over responsibility from SDNC, breaking µS concept, scaling concerns etc. Maybe consider/discuss this again later e.g in J-release
Preferred option for Model ingestion: direct from xNF (based on change event from A&AI)
Question on SON Use Cases: Model information is information, Niamh Core will send an email. Also please confirm SON use case is stil considered for I timeframe.
Need alternative solution but Renu Kumari will comment and propose way forward Regarding OOM Renu will also create a general OOM-updates ticket based on a pattern used in 'Policies'. Any OOM updates can be added as task to that ticket. Traditionally this was handled at end of any release but we are awaiting ng an OOM process improvement to have an earlier staging release to make these changes. Renu will communicate to team and OOM about this process
Discussion with E2E Network Slicing regarding 'hardcoded ran-network-model':
Swaminathan Seetharaman (or his team) will investigate the feasibility of model-retrieval using RESTConf and NetConf from the Honeycomb(?) simulator used for their use-cases. Following the produce investigated and documented by Rahul Tyagiin

INT-1904
A&AI does currently not include/cover the simulated nodes used by E2E NW Slicing. NCMP should NOT try to solve this using SDNC/R or similar. If needed a 'shortcut' using a hardcoded list(file) with the simulator data until this functionality is added to A&AI.
A dedicated ONAP-Honeycomb-DMI plugin could be considered if needed e.g. if models can not be retrieved over RESTConf.
At the same time it might be required that NCMP in the I timeframe support both simulated nodes and nodes available in A&AI. Prioritization and feasibility (depending on resourcing too) of these options need to be discussed
At boot time of DMI Plugin it will need to inform NCMP (DMI-Registry) of all CMHandles its manages
Spikes by Bruno and Renu to be reviewed by remainder of team (follow up meeting early next week)
CPS-36. Rishi remarked there is no docker-file yet for TempDB. Wil create separate task to do that first
Discussion on the fact TempDB is juts one module. It was greed that for simplicity it wil be kept like that until the need arises to split it. Bruno is also introducing an Architecture Quality Tool to ensure the singel module still has a god architecture that can always be dived into modules in the future
TBDMT. Question arose around need for (read-the-docs) documentation etc. Toine Siebelink will the requirement for TBDMT and make sure documentation is part of that.
New tasks suggested
Update read-the-docs for CPS with high level description of its components
Update & reorg wiki with good overview of current architecture of CPS and its components
Note. Pass-thru wil include write operations. In Istanbul release only full re-sync wil be available to update CPS Core Cache after write operations...
E2E Network Slicing Update
Simulator findings, not available yet but Honeycomb is intended to be fully NetConf compatible. It might mean impacts on simulator are required...
Short discussion re. SDNC & SDNR Tony Finnerty & Swaminathan Seetharaman SDN Controller is Prime interface for CM to Network. Owns the interfaces to network. NCMP owns the cached data. NCMP that requests models & data from controller as needed.

(done)
Model operations are NOT part of the interface discussed. But a (Separate) interface for this is planned and minimal support in Istanbul timeframe is required
NCMP wil use different datastores (dataspaces) for the same and/or slightly different models for the same xNFs. This might requires soem attention/future optimization
Possible on SonarQube coverage reporting in CPS-Temporal . Bruno Sakotowill create bug to address this
CPS is part of Trial for new way working for SonarQube:
ONAP Way profile created (copy of Sonar Way) which gives us control of when SonarQube updates come in
PTL (Toine) has now capability to flag false positives and mark Security hotspots as 'safe'.
Discussion regarding exact scope Istanbul
E2E Network Slicing detailed requirements
Will use CPS-Core only.
Upload model using rest endpoint as needed
CRUD Operations against data in CPS-Core only for now
TBDMT will have some minor impacts when switching to NCMP interface at a later stage (ie. specify dataspace). In any case it seems required that TBDMT can interface with both CPS(core) and NCMP
Ownership of data is important but does not require impacts in Istanbul
Update on Simulator investigation
Honeycomb RAN Simulator should have capacity to retrieve model over NetConf/RESTConf interfaces using ODL
some open issues left re. datastore names and (fallback) behavior
REST URI format agreed
Ahila P Some clarification required re. DMI-Plugin, node, model and data discovery
Step 1 Node Discovery - If E2E simulation node not in A&AI: DMI PLugin has side-door REST endpoint to add (initial) inventory
Step 2 Model Discovery After node is Added, NCMP wil trigger Model Discovery when needed 2a NCMP wil request list of module (name)s from Node 2b NCMP wil request yang-source for any module sit hasn't stored already (for other nodes)
Junfeng Wang has some concerns about pre-conditions for node discovery. Ahila will add these details later
DMI-Plugin interface, abstraction that allows flexibility to have other ways of discovering initial inventory and inventory changes. Intention is that ONAP will only have one DMI-Plugin. Using a temporary 'side-door' to add any cm-handle not available through A&AI
Step 3 Data Sync Not worked out yet Similar process and component involvement as Model Sync
is not a bug but a task or user story that needs to be executed as part of E2E slicing use case support
Latest findings on config=true/false support using SDN-C/ODL by Rishi Chail: ODL supports 'content' parameter and translates it to the equivalent NetConf operation(s). However current the tests how the same output even tough some elements are flagged as config 'false'. Claudio David Gasparini suggests using a different simulator to identify where the problem is. is and wil help Rishi with this. Oskar Malm noted that most current nodes do not support NMDA datastores (yet) So intention for Istanbul is to only support non-NMDA devices. Non-NMDA device will also use one model for config-false and config-true data.
Michael Kerrigan Build problems, need to check what test is failing exactly
Renu KumariNeed agreement on Kafka default authentication options and population of related env. variables. Agreed to 'follow' CPS-Core but further discussion needed with Bruno and Aditya. Docker compose setup for Kafka, Agreed to handle taht as separate task for CIST testing. Renu Kumari will create ticket for that
