|---|---|---|---|---|---|---|---|
Connection to cloud infra | Address and capabilities of VIM managers (e.g. openstack port) | Mult-VIM: will register/unregister VIM with ESR, the register VIM from ESR portal and need the health check function of VIM. | Yes | ||||
| VID: manually input the VIM addresses and connection information to the portal, and sent this info to MSO which later call controllers which interact with all of these systems (VNFMS , VIM , EMS) | No | Avi from amdocs (avi.chapnic@amdocs.com) | |||||
| VF-C: query get the VIM addresses from ESR. | Yes | ||||||
| SO: will not interact with external system VIM directly | No | jin xin | |||||
Connection to transport | SDN controller address’s and capabilities | vendor sdn controler which managed by VIM is not in the scope of ESR. How about the vendor sdn controller managed by ONAP SDN-C? There is a request about API used to verify that platform is available from SDN-C release plan. ONAP SDN-C: ? | ONAP SDN-C: For SDN-C, we are considering use of ESR for managing credentials with external SDN controllers as a "stretch goal" for release 1. Ultimately we do see a benefit to using ESR, but if we find that we cannot do so in release 1 without jeopardizing our dates, then we would just use local properties files for release 1 (as we did in our seed code) and integrate with ESR in a later release. | Yes | no response | ||
Connecting to S-VNFM | S-VNFM and capabilites | VF-C: manage VNFM addresses from ESR | Could be part of the tosca/heat template | Yes | |||

Stephen:
Based on the above, I understand that the Functionality that ESR provides is to enable a common means to input the addressing information required to enable ONAP to contact these external systems. That functionality does seem like a good idea. If we turn our attention to what is required, this seems to required:
- A means to input the addressing information
- A place to store the addressing information
- A means for the ONAP modules to retrieve this information.
A assume the means to input the addressing information should be using the SDC environment, I mean it isn't optimal to have another creation environment with a different look and feel.
Part of the discussion as I understand is to store this information into A&AI, actually it is kind of static inventory information - is this a decent fit - it could be better than having yet another storage to deal with.
If the above was correct, then I guess that ESR somewhat becomes a proxy for the address information, is that required or could that be directly retrieved from the storage instead, and the ESR project focusses on creating the module required in SDC to input the data and place it in the storage instead of having a proxy?

RE: Stephen
Actually, SDC has nothing to do with ESR. SDC runs at the design time, while ESR runs at the run time. ESR provide a portal for user to input the external system address information.
The data stored to A&AI from ESR included the addresses information and the status of external system. In my opinion, it is just like the instance data stored in A&AI.
We have reached an agreement with Jimmy(the PTL of A&AI) that ESR team will be committed to working the necessary A&AI features and interface agreements to support making A&AI the datastore for ESR data. The portal and update functions can be a separate microservice and would use A&AI as the database.
