David,

This is one of those service provider options.

Today, we use APPC for Openstack operations like 
start/stop/restart/migrate/evacuate/etc?  even for L3 VNF because we liked 
having all the Ppenstack operations in one controller (a vCE and vSBC look the 
same for operations like stop/stop the VM). We tie that into our closed loop 
and our change management functions.

The functions that APPC uses (both northbound and southbound) could work on an 
SDNC instance (they advantage of the common platform) but we haven?t seen the 
need yet. Generally we have used APPC as both a L4-L7 configuration manager as 
well as a (L2-L7 ) cloud VNF Manager. SDNC has L2/L3 configuration, signaling , 
L0/L1 interface and in some instances our neutron agent for cloud networking.

Since SDNC can call APPC functions through REST (or through the call node if 
they were co-resident) we haven?t worried too much about the VNF manager 
boundary. This also stems from the fact that most L2/L3 VNFs are relatively 
simple compared to the L4-L7 VNFs we see in vIMS and vEPC.

That being said if a service provider had strong desires to separate them then 
it would be feasible to use the VNF Manager functions out of SDNC but would 
require some integration work (karaf feature bundle dependencies).

Out of the box in ONAP, APPC is the one listening on DMaaP/MR for events and 
has the adapter  (cdp-pal) to talk to Openstack so I would recommend using APPC 
in that mode.

Hi Daniel.

For clarification, in the context of an L3 router.
