Open Issues & Decisions

#	Description	Notes	Decision
1	How to deal with hardcoded E2E NW Slicing model, spike	23 Apr 2021 Discusdons started with E2E NW Slicing Team, to be continued next week
2	Which Simulator to use? NetConf Simulator Netopeer v2 Nokia Ericsson Honeycomb(?) 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	For E2E use case Honeycomb simulator wil be used. If needs be for certain non E2E functionality where this simulator has limitations the team can still decide to test/develop against NeToPeer simulator
3	Should (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
4	What datastores are supported/recognized by NCMP Interface in Istanbul Release	Suggested, see Datastore paths and format combinations section below `ncmp-datastores:operational` (will use cached data when sync=On) `ncmp-datastores:running` (will forward to DMI-Plugin in Istanbul release) `ncmp-datastores:passthrough-operational` (always forward to DMI-Plugin) `ncmp-datastores:passthrough-running` (always forward to DMI-Plugin)	Suggestions in previous column were agreed in CPS Weekly meeting 04 Jun 2021
5	What datastores are supported/recognized by (ONAP) DMI-Plugin Interface in Istanbul Release	Suggested exact same as NCMP supported options `ncmp-datastores:operational` (for cmhandles with sync=Off) `ncmp-datastores:running` `ncmp-datastores:passthrough-operational` `ncmp-datastores:passthrough-running`	Suggestions in previous column were agreed in CPS Weekly meeting 04 Jun 2021
6	How to handle any other (custom) datastore value		Agreed in CPS Weekly meeting 04 Jun 2021 : Both NCMP and DMI-Plugin wil not support any other datastore value in the Istanbul timeframe
7	What 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 1: This method (hidden REST endpoint) is expected to be a temporary solution, additional options are part of stretch goal (#13).
Note 2: Adding the initial inventory should also trigger a model-sync for each node in that inventory (step #8)
