SO1: SO support of A&AI creation | [SO] A&AI UI can create an inactive PNF (inactive) A&AI entry. In Step #19A instead of EXITING, SO would go into WAIT STATE pending rehydration of RLF w/ pnfReady DEVELOPMENT STATUS:

| SO2: Service & NF Instance Association | Associating a xNF to a Service. Seen in the VID UI, after instantiation waiting for registration see only a Service instance, and beyond that a PNF resource instance associated with it. DEVELOPMENT STATUS: | ||||||||||||||||||||||||||||||
SO3: SO support for already existing PNF A&AI entries | [SO] Support of SO for an already existing PNF (active) A&AI Entry (use case with a deleted & recreated service or instantiating 2nd service using the same PNF) DEVELOPMENT STATUS: In ONAP/Casablanca this was updated, and irrespective of AAI entry existence for a PNF instance, the workflow execution always waits to receive a PNF registration event.

AAF SECURITY IMPACTS
PnP DUBLIN WORK ITEM | DESCRIPTION | ||||||||||
AAF1: Security Enhancement | [AAF] Security enhancements slated for Dublin will need to be working for PnP Use Case. Discussing with DCAE about supporting TLS authentication just with Certificate without Username & Password. If the NF already uses the UN&P for the HTTP connection (that should still work). Certificate use should be working in Dublin to setup the HTTPS connection. PROPOSAL: Thus, both Certificate & Username & Password will be supported. (This is suggested for backward compatibility). i.e. there are already existing deployment. PROPOSAL: It is recommended to use the Certificate. Certificates as part of the authorization? Subject of the certificate is something that can be used as authorization, the proposal to DCAE is that there is a list of authorized users/subjects. Initially it could be manually configured, but the objective is that this would come from AAF. Start with Certificates local check: subjects against a list (w/ wildcards). Agree w/ appropriate interface w/ AAF then integrate w/ AAF. If identity not found use basic authentication a second check w/ username & password. otherwise access is rejected (HTTP return code).

PnP DUBLIN WORK ITEM | DESCRIPTION |
CTL1: Controller PNF Interaction | [CONTROLLER] Controller definition (SDN-C) came so late in Casablanca, we had defined some additional optional parameter for the step37 Service Configuration but likely more evolution needs to be done. SDN-C was not the theoretical proper controller and people objected as this is conceptually the L0-L3 controller. [STEP 35-37] - The SO to SDN-C and Controller to PNF exchange (Ansible or NetConf) was a carry-over item from R3. This requires that an API between SO to SDN-C is in place to support this. It requires that SDN-C support the appropriate Ansible Playbook and Directed Graph. Generic API. CDS has its own API to SO. The work being done with the CDS work is re-used for PnP U/C, so no new development needs to be done. ASSOCIATED DEVELOPMENT: (Jira) Controller Design Studio (Design Time) - to customize configuration. This might be used to set the values of parameters that might be send down to a PNF. NetConf - see the NetConf 5G U/C Wiki: 5G - Configuration with NETCONF |

| PRH1: A&AI New PNF Schema Adaptation | New A&AI schema adaptations: Chesla Wechsler found a discrepancy between PNFs and VNFs; VNFs are identified via VNF-ID (UUID), and PNFs - via PNF-name. So PNF-id should be used for Identities. This differentiates the way that PRH is searching for PNFs in A&AI, when PRH does the PNF registration in A&AI (may also require SO change). A PNF-name parameter will be used to search a relevant PNF instance, and then CRUD operations will be executed using the PNF-ID value obtained from that previous instance search. PNF-id = UUID; PNF-name = Correlation ID. PRH use search API to find PNF instance based on PNF-name then get the PNF-id. pnfRegistration VES Event to get the Key to search A&AI. use "sourcename" (part of VES Common header). Take value of sourcename search A&AI to find a PNF entry. In R3/Casa search against PNF-name = sourcename (search for object get PNFid); In R4/Dublin search against PNF-name = sourcename (with a different API). search for object.

VID ENHANCEMENTS
PNF PnP will have a Portal Interface update in R4.
Functional menu accessible to any ONAP users from portal.
The Portal project provides a seamless user experience when multiple back-end components involved e.g. SDC, VID, A&AI etc
When user goes from one component to another e.g. modeling, pnf instance declaration, activation. These provided as functional menus in PORTAL.
If a new user doesn't know what the next step is to perform, the PORTAL can recommend the next step via notifications or alerts.
