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
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

Initial Inventory (semi hardcoded e.g. hidden rest endpoint

E2E Network Slicing

Jira

server	ONAP JIRA
serverId	425b2b0a-557c-3c0c-b515-579789cceedb
key	CPS-382

CPS/NCMP

create rest interface on northbound for GET/POST/PUT/DELETE to access yang data.
Note. Currently driven by "E2E Network Slicing" Use Case mix of CPS-CORE and NCMP Interface

interfaces for yang data are: operational, intended, pass-through (selection can be done by parameter)
check with netconf-sim if current nw slicing yang model can be imported including its imports.

(NCMP) DMI-Registry

Create dmi-registry. Data Model Inventory Interface (DMI)

'Internal service' no public Java or REST API

responsibilities are

Store & retrieve cm-handle/dmi-plugin mapping in yang modelled CPS data table.
1. include additional data (key-value pars as provided by dmi-Plugin)
Dmi manager is to select the dmi instance at runtime for cm handle for a northbound (write) request

DMI-Plugin

server	ONAP JIRA
serverId	425b2b0a-557c-3c0c-b515-579789cceedb

DMI-Plugin (ONAP impl.)

Common standard (REST and Java?) interface for extensibility

create dmi plugin for onap. Its responsibility of admin to provide instance of dmi.

extract dmi-plugin into separate container consensus on rest interface is needed.
