Hi Yang / PNF Team,
Thanks for the links to ppt and demo video. Let me summarize my understand
below, please validate it :
- A PNF is getting *mimicked* by using a VM baked by HEAT Template.
- In SDC a PNF is being introduced a resource and same has been used in
a Service, which is then getting distributed. Lets say we name that service
as PNF Service.
- The only item that ties the PNF running in the network ( i.e VM ) and
PNF Resource in SDC is the *Correlation ID* .
- The instantiated PNF will start sending VES events to DCAE VES
Collector. Initially these events will get ignored as ONAP doesn't know
what to do with these events as no one has subscribed to that topic. When
the PNF Service is instantiated via SO through VID, then SO notifies to
DMaaP that it is interested in learning all messages with topic
*<Correlation
ID>* . From this instant, DMaaP ties both ends together and SO reports
back to VID that service is successfully instantiated by ONAP.
If my above understanding is correct, then I have following queries. Could
you please clarify ?
- PNF Modelling in SDC seems to be very abstract i.e It just says "This
resource is a PNF" . That's it. It doesn't distinguish between Layer1,
Layer2 devices. The datamodel of PNF varies between layers and between
vendors and between versions. Also it comes with environment specific
details like Building/Rack/Slot/Card/Port details. Tracking this
information is very much necessary for complete flow. Is there any working
happening in that front in future releases ?
- The difference between VNF Instantiation and PNF instantiation is
*Discovery*. Unlike VNFs, PNFs cannot be just cloned and created. A PNF
is supposed to be shared between network services. Has AAI been updated to
support this kind of sharing? Could you please point me to right links to
learn AAI side of the story?
- PS : I'm aware of Allotted Resource Model . This is WIP and doesn't
really work with PNFs. Is there any work happening / happened w.r.t PNF
Inventory, apart from this Allotted Resource Model?
BR,
Viswa
