Implementing Data Notifications & Subscription Notifications on a US by US basis

5
CM Handle Connectivity Freshness/Staleness

Need to model what staleness is (current CPS only has concept of model-sync state, nothing about connectivity)
kieran mccarthy to spec this

Staleness will be modelled as a public property and notification will be sent/ notifiable. 
Assumption is that the solution will accommodate the same behavior's for all public properties.

Update YANG schema-set for CM handle using ModuleSetTag
  1. Update YANG schema-set for CM handle without removing and adding it
  2. Cached data is not in scope.
  3. Need to specify orphan handling of YANG modules (already built in ?)
  4. Introduce concept of ModuleSetTag to prevent unnecessary trips to nodes to get al Modules
  5. will require NCMP module loader (for upgrade of Inventory model) instead of Liquibase steps!

Support NCMP-CPS upgrade

Currently only custom upgrade is supported. (upon request)

Requirement: It shall be possible to upgrade NCMP-CPS from release N-1 to N (without requiring manual intervention/workarounds). N is defined as any release requested by ESH

  • Note. Need to agree version strategy: use current ONAP x.y.z. numbering. Ericsson to communicate when a version is to be 'delivered' and 'y' increased

Technical Debt to be addressed: Liquibase is used in CPS to manage data(upgrades) in CPS

Study: Resolve technical debt (mixed data). NCMP Data upgrade. CPS Core need to support model upgrade so that NCMP can use it,

(XL) - Scope needs to be defined. Risk is scope not identified, efforts might increase.

CPS-1345 - Getting issue details... STATUS

TBC

Support multiple identifiers (alternatives for CM Handle ID)

(M) - Not sure. Scope not known yet. 


17
Access control for topics which are created by NCMP .Spike needs to be conducted. 
18
Invoke YANG modelled action

Always on operational datastore.  Supported for nmcp:passthrough-operational and if executed against ncmp:operational then it is always forwarded to dmi plugin.  Is there another story for forwarding to be included as a dependency? Always run as async request.  Is this dependent on CPS-1127  - see spin-off user stories table below this on.

KMC : Can we deprioritize - this can be run against passthrough-operational for now.  Just have to agree on the API / URL for the action to progress at this stage so that the passthrough-operational form is aligned with final operational form.

(S) - for passthrough. 

*Spec out before Sept'23. No implementation. 


19
Enhanced query support (fields)

Currently the passthrough has an 'fields' parameter to do a scoped query.  Propose to support this in non-passthrough so it is promoted to a fully supported option, e.g. {ncmp-root}/ncmp/v1/ch/335ff/data/ds/ncmp-datastore:passthrough-operational?
              resourceIdentifier=/&options=(fields=ericsson-enm-comtop:ManagedElement/ericsson-enm-
              gnbcucp:GNBCUCPFunction

KMC : Do we support restconf like queries or xpath only?

(L) .

*Spec out before Sept'23. No implementation. 


20
Enhanced query support (scope)

Currently the passthrough has an 'fields' parameter to do a scoped query.  
              scope=ericsson-enm-comtop:ManagedElement/ericsson-enm-gnbcucp:GNBCUCPFunction/
               EndpointResource/LocalSctpEndpoint/attributes(interfaceUsed==X2))

Support ncmp-datastores:running for reading data (single CM handle, synchronous only)See CPS-391 page for details about supported operations and combinations. Note: There can be some overlap between work items for #5, #6, #11 and #12.

Read from operations.

(S) - Forward only.  No validation or data enhancements (add prefixis)

22TBCSupport ncmp-datastores:running for writing data (single CM handle, synchronous only)(S)  As per #18

Support relationships for 'Instance Identifier'Should be possible to identify a cmhandle using multiple instance identifiers.
(M) - Not sure. Scope not known yet.

Support for HTTPS and authentication

  • Use Service-Mesh? Both ONAP and Ericsson (applied ISTIO using Envoy Proxy side-car) are working towards this. Check with Gareth Roper 
Validation required whether this is still needed.

Vendor Neutral

If this project is coming from an existing proprietary codebase, ensure that all proprietary trademarks, logos, product names, etc. have been removed. All ONAP deliverables must comply with this rule and be agnostic of any proprietary symbols.

Free and Open Source Software

FOSS activities are critical to the delivery of the whole ONAP initiative. The information may not be fully available at Release Planning, however to avoid late refactoring, it is critical to accomplish this task as early as possible.
List all third party Free and Open Source Software used within the release and provide License type (BSD, MIT, Apache, GNU GPL,... ).
In the case non Apache License are found inform immediately the TSC and the Release Manager and document your reasoning on why you believe we can use a non Apache version 2 license.

Each project must edit its project table available at Project FOSS.

Charter Compliance

The project team comply with the ONAP Charter.
