The PNF PnP flow is method, which allows to register within ONAP/AAI a PNF resource instance. This PNF resource instance is correlated with an existing service instance.
Once a PNF resource is registered, the infrastructure service instantiation flows are able to continue the service instantiation, by calling controllers, which in turn configure the PNF instance.
While this page was created in the R2 "Beijing" release, it is the "Base" Plug and Play page and applies for R2 through R9 (Honolulu).

OVERVIEW OF PNF Plug and Play
...
PNP-1320 [PNF] - [FUTURE R4] The PNF Vendor shall provide a PNF Descriptor for Design time SDC Design Studio input based on ETSI-NFV-IFA014v242 (see 48534348 5G-PNFPlugandPlay-STAGE1-PNFDESCRIPTOR for more details)
PNP-1330 [PNF] - The PNF Vendor MAY provide software Version(s) to be supported by PNF for SDC Design Studio PNF Model. This is set in the PNF Model property software_versions.
...
PNP-4210 [PNF] – The PNF MUST support sending a pnfRegistration VES event. This is detailed in the “PNF Registration VES Event” section of the Plug and Play wiki page at: 48534348 5G-PNFPlugandPlay-STAGE3-PNFREGISTRATIONVESEVENT
Note: See the Vendor PNF PNP Deliverables (in the ONAP DOC Project) URL/Wiki: https://onap.readthedocs.io/en/latest/submodules/vnfrqts/requirements.git/docs/Chapter7/PNF-Plug-and-Play.html
...
Note: These are detailed in the Stage 5 PnP Use Case at: 48534348 5G-PNFPlugandPlay-STAGE5-PNFACTIVATIONREQUIREMENTS
Note: These parameters are optional, and not all PNFs will support any or all of these parameters, it is up to the vendor and service provider to ascertain which ones are supported up to an including all of the ones that have been defined. Note: It is expected that there will be a growing list of supported configuration parameters in future releases of ONAP.
...
Note: The exact criteria, when to classify a pnfRegistration message as "initial registration" or "re-registration" are stored here: PNF Re-Registration criteria
PNP-6410 [DMaaP] – There shall be created a static pnfUpdate DMaaP Topic.
...
| STEP | DESCRIPTION |
|---|---|
| x | REQUEST LICENSES - The PNF, for example 5G RAN PNF (DU) contacts the License Service to request licenses. Note: This step is optional. This step is labeled "X" because it can be initiated any time after stage 3 in the Plug and Play flow. |
| y | RESPONSE WITH LICENSES - The License Service responds to the request for licenses to the originating PNF. Note: This step is optional. This step is labeled "Y" because it can be initiated any time after stage 3 in the Plug and Play flow. |
SUMMARY OF R3 CASABLANCA PLUG AND PLAY ENHANCEMENTS
The follow describes a summary of the Casablanca Enhancements for Plug and Play
...
TOPIC | DESCRIPTION |
PNF Registration Handler (PRH) Improvements | pnfRegistration Domain - New VES Event domain for PNF registration with corresponding support in VES collector, DMaaP and PRH. PRH & AAF Integration – intra-ONAP security improvements Integration – Integration of Beijing software deliveries. DU Simulator Update – Support of new domain and updates to the DU simulator to match changes made in Casablanca. |
SO Workflow enhancements | Integration - Introduction of dedicated 5G use case work-flow. While the PnP Work-flow was coded in Beijing it was not delivered in that time frame. PNF Controller Interaction – SO to the PNF controller interaction is developed in Casablanca (R3). |
Service Configuration Improvement | PNF Controller – Service configuration improvements from PNF Controller to PNF after PNF registration to PRH. Five optional parameters are requested to be supported with the Casablanca release (R3). |
Security Enhancements | Security Enhancements – Authentication, Certificates, User name & password and intra-ONAP security are used by the Plug and Play Use case. |
Modeling enhancements | PNF Model – Modeling enhancements to support 5G PNF in ONAP with support for the new SoftwareVersionList parameter. |
PNF Onboarding / Package | PNF Package - Defining PNF Onboarding Package. Extending framework to work with PNFs. Defining PNF Package framework. The PNF package artifacts will be delivered in Dublin such as the PM dictionary and FM Yaml dictionary. The definition of these are explored in Casablanca. |
