(sko) add link to the document
overview of all new interfaces with SDN-R
NeigborListChange notifications
mapping between pnf-name (DU-Name) which is unique and cell-name
each DU has a NetConf server - there is no NetConf server per Cell
Open question: about partial failures between all involved components
deterministic behavior expected
DB on SDN-R is MariaDB - as introduced by CCSDK

Next steps

swagger.json for ONAP components
yang module for SDN-R and the RAN simulator

I think pnf-name just needs to be unique and value provided at service instantion == value provided by PNF at registration. The proposal for pnf-name is to use first 3 letters of vendor name + serial number. I suppose it would change if there was hardware swap out?

If there is a name change of PNFs due to any operational reasons, then does it mean that we will have to change in SDN-R? If we were to use ID, then changing any names would not cause downstream impacts.

from demx8as6 to all: 06:34 PM
here the pnf-name is a global identifier - if you change it you basically "delete" an existing pnf and create a new one. - so I assume there is a whole process behind

from Rebecca Lantz (Ericsson) to all: 06:41 PM
will YANG model be hardcoded in SDNC? Or retrieved from SDC? Or retrieved from PNF?

from demx8as6 to all: 06:45 PM
at least retrieved from PNF (NetConf-Server) - there might be an advantage to add yang models in advance to ODL (but not mandatory)

from Rebecca Lantz (Ericsson) to all: 06:48 PM
ok so config database will use RFC 6022 <get-schema> on NETCONF interface. Thanks.

from demx8as6 to all: 06:50 PM
yep
