Implement -async option for CRUD and Patch operations (for one CM-Handle)

Required for potentially long running requests

Note below to be agreed.,,

/ncmp/v1/data/ch/123ee5/ds/ncmp-datastore:*?topic=<topic-name> 

Accept : application/yang-data+json, application/json

Responses always published by NCMP to the client topic.

dmi-plugin may publish to NCMP on a local/private topic.  Response event payload contains the public topic name.

Note 1. There can be some overlap between work items for (CPS R10 Release Planning #5, #6, #11 and #12)
Note 2. This item doesn't include accessing cached data as data sync is not available yet. If no cache data forward ncmp-datastores:passthrough-operational?!

CPS-1133 - Getting issue details... STATUS

  • CIST Tests for Data-Sync


10

REQ-1281 - Getting issue details... STATUS Requirement 
E2E Slicing for next release!

CPS-NCMPSupport update of cached data through a message driven solution
E.g. TBDMT/SND-R will write to device and can send message on NCMP provide message topic to keep cache up to date		Need to investigate if DMaap or new Kafka/Strimzi message bus should be used

11
CPS-NCMPRegistration Performance

NCMP shall register new cmhandles (to READY state) at a rate of x cmhandles/second (assumes no dmi-plugin delays, assumes 180 modules per cmhandle with 95% module overlap between cmhandles, assumes cache disabled).

Treat this as a black box requirement.  May mean underlying requirement to have multiple instances, memory requirement etc.  Focus right now is 23.Q1 timeframe.



12
CPS-NCMPDeletion PerformanceNCMP shall delete/remove cmhandles (to DELETING state) at a rate of 50 cmhandles/second with cache disabled (assumes no dmi-plugin delays, assumes 180 modules per cmhandle with 95% module overlap between cmhandles)
Note: check with Gergely on priority as DELETING state will prevent user to act on cmhandle

13

REQ-1281 - Getting issue details... STATUS

CPS-NCMPInvoke 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.



14
CPS-NCMPEnhanced query supportCurrently the passthrough has an 'option' 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/EndpointResource/LocalSctpEndpoint/attributes(sctpEndpointRef),
              scope=ericsson-enm-comtop:ManagedElement/ericsson-enm-gnbcucp:GNBCUCPFunction/
               EndpointResource/LocalSctpEndpoint/attributes(interfaceUsed==X2))

15
CPS_Core / CPS-NCMPUpdate YANG schema-set for CM handle without removing and adding it

Cached data is not in scope. Need to specify orphan handling of YANG modules.

Needed for node upgrade scenario.



16

CPS-1135 - Getting issue details... STATUS

CPS-NCMPRetrieve single module resource/v1/ch/{cm-handle}/modules/definitions/{moduleName}

17
CPS-Core / CPS-NCMPExisting CPS-path based queries across all CM handles for cached data

Look to define the interface specification for this only.

(but best way is to implement for operational/cached data to determine any output formatting issues)



18
CPS-Core /
CPS-NCMP		Access control for public interfaces (NCMP, CPS-Core, DMI?)


19
CPS-NCMPFine-grained cache configuration


20
CPS-NCMPSend notification for updated CM handle metadata (public CM handle properties or YANG modules)


21

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

28(ONAP) E2E Slicing Use-Case

Support dynamic inventory changes (ONAP DMI Plugin)

React to events from AAI sent over DMaaP, in turn using Inventory API for updates.
Strimzi-Kafka Bridge might be an alternative, check with Fiachra Corcoran  on the latest for this when implementing this ( DMAAP-1681 - Getting issue details... STATUS )

Possible in a generic way or it can also listen to similar events sent by SDN-R  (as suggested by Ahila P)

Longer term roadmap

  • CPS-Core will have extended query capabilities based on XPath expression.
  • CPS-Core will enforce and control ownership of data it holds
  • NCMP will be to able to 'detect' and sync xNF in the network
    • Fine-cache cache control will determine what get cache for what xNF
  • NCMP will support the query capabilities as CPS-Core and be extend with options similar to RESTConf's 'fields' and 'depth'
