SDC is a key component from ONAP perspective as it drives the design time 
artifacts distribution across all the other components.

Yes, adding to the points mentioned by Srini.
The Runtime components register for a specific type of format that SDC would 
support.
This is then notified by SDC through a Message on an update to the catalog.
The runtime components would then pull the requested format and would process.

Its also important to note the parsing logic by the runtime components like SO 
uses the SDC parser to parse the artifacts.

time vs ONAP Design time)

Hi Srini,

When a Service Model is distributed..

1.       A notification(TRIGGER) is sent to runtime systems.

2.       Runtime Systems fetch(PULL) the Service CSAR and bunch of APIs 
published by SDC for Runtime systems. Service CSAR has a agree structure 
containing TOSCA Model and various Artifacts(e.g., License Model).

Where(which company or person) is this question coming from?

Subject: [Onap-arc] Functional decomposition related question (ONAP Run time vs 
ONAP Design time)

Hi Michael, Brian, Seshu and all,

While explaining ONAP at high level to somebody who is novice to ONAP, but very 
knowledgeable on network service orchestration, few questions came up on 
functional decomposition and I did not have good answer. May be you could help.

Today, ONAP design time is used to onboard VNFs, compose services using VNFs.  
ONAP SDC notifies ONAP run time when new VNF is onboarded, or service is 
changed etc…   ONAP run time comes in picture when the onboarded/composed 
service is instantiated.

Questions that came up were :

-          Can ONAP run time be used with some third party onboarding tools (My 
sense is that they have very good onboarding tool and hence likes to use that 
and use ONAP run time)? What kind of glue logic is expected to be developed?

-          Digging deeper:

o   What does ONAP-run time expect? How do services and VNFs artifacts would 
need to look like for ONAP-run-time?

o   What needs to be programmed in A&AI before allowing service instantiation.

o   What needs to be programmed in SDNC, Policy, DCAE, Multi-Cloud if there is 
no SDC?

Did you see this kind of decomposition request come from anybody? In any case, 
is there something that is documented to answer above questions?

Thanks
Srini
