#DescriptionNotesDecision
1How to deal with hardcoded E2E NW Slicing model, spike

  Discusdons started with E2E NW Slicing Team, to be continued next week


2Which Simulator to use? NetConf Simulator Netopeer v2
  1. Nokia  
  2. Ericsson 
  3. Honeycomb(?)
  4. lighty netconf simulator

Rahul Tyagi Ericsson more lightweight, more experience.
Available CSIT standard setup

Swaminathan Seetharaman mentioned 'Honeycomb' simulator they used before. Need to investigate if it supports get-schema method over RESTConf/NetConf

Need to check if we can use it with E2E NW Slicing model


3Should (ONAP) dmi-instance be  as separate (springboot) application
Could be part of DMI Manager		DMI-Instance interface should be an open standard

Tony Finnerty and Team to allow easy integration of future 3rd part DMI-Plugin instances a separate application with its own REST Interface is required

4What datastores are supported/recognized by NCMP Interface in Istanbul Release

Suggested, see Datastore paths and format combinations section below

  1. ncmp-datastores:operational (will use cached data when sync=On)
  2. ncmp-datastores:running (will forward to DMI-Plugin in Istanbul release)
  3. ncmp-datastores:passthrough-operational (always forward to DMI-Plugin)
  4. ncmp-datastores:passthrough-running (always forward to DMI-Plugin)

Suggestions in previous column were agreed in CPS Weekly meeting  

5What datastores are supported/recognized by (ONAP) DMI-Plugin Interface in Istanbul Release

Suggested exact same as NCMP supported options

  1. ncmp-datastores:operational (for cmhandles with sync=Off)
  2. ncmp-datastores:running
  3. ncmp-datastores:passthrough-operational
  4. ncmp-datastores:passthrough-running

Suggestions in previous column were agreed in CPS Weekly meeting  

6How to handle any other (custom) datastore value

Agreed in CPS Weekly meeting  : Both NCMP and DMI-Plugin wil not support any other datastore value in the Istanbul timeframe

7What to do with old CM-Proxy interface implemented in H.Methods never really used by E2E Network Slicing team. Methods will be 'deprecated' using Open API option for that.. Replace and refactor other layers as needs when new methods using the new API are being implemented

Support method to add initial inventory (e.g. hidden REST endpoint on ONAP DMI plugin)

Additional properties for ONAP plugin may need ODL mountpoint, stored by NCMP and later provided to DMI plugin for each request. The mountpoint is created outside of CPS and DMI plugin.

Note: This method (hidden REST endpoint) is expected to be a temporary solution, additional options are part of stretch goal (#13).

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

Some existing CPS-E-05 APIs may be removed or deprecated if not currently used. See Decision #7

In addition to external APIs, extensions may be made to the CPS Core library to support some NCMP use cases. Plugin APIs will also be added to support communication between NCMP and DMI plugins.
