SO IMPACTS

PnP DUBLIN WORK ITEM	DESCRIPTION
SO1: SO support of A&AI creation	[SO] A&AI UI can create an inactive PNF (inactive) A&AI entry. A Service provider might use an inventory system and A&AI UI to create a PNF A&AI entry. In Step #19A instead of EXITING, SO would go into WAIT STATE pending rehydration of RLF w/ pnfReady DEVELOPMENT STATUS: This is already covered in ONAP/Casablanca: SO-797 - Getting issue details... 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) Within ONAP/Beijing - In Step #19B SO would exit and service creation would continue 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. SO-797 - Getting issue details... STATUS This is not planned to be changed in ONAP/Dublin release.
FUTURE (El Alto)
SO-future: Controller Association [FUTURE MOVED TO EL ALTO]	[SDC/SO] The PNF controller caused quite a stir in Casablanca, the tension between Design/Platform Model vs Run-Time/Deployment Model. As a result the SO controller design was sub-optimal and should be addressed in Dublin.
SO4: SO to support updated A&AI PNF schema	[SO] Support of SO for updated AAI PNF instance model. PNF-ID is going to be used as unique PNF idenitifcator, instead of PNF-Name, used in ONAP/Casablanca. PNF PnP sub-flow might need modifications related to how PNF instance objects are created. Added March 13th 2019 → AAI team got a recommendation from architecutre committee to defer this item to ONAP/El Alto release. ASSOCIATED DEVELOPMENT: See task A&AI1 and PRH1. JIRA: (Depends on the A&AI work: AAI-2096 - Getting issue details... STATUS ). SO-1273 - Getting issue details... STATUS SO-1277 - Getting issue details... STATUS .

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).

SDN-C/R (Controller) IMPACTS

The Controller to PNF service configuration happens in Steps 36 & 37 in the PNF Plug and Play flow (you can read more at the PNF PnP Wiki).

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

PRH IMPACTS

PnP DUBLIN WORK ITEM

DESCRIPTION

PRH2: Integration

[PRH] There might be more integration or development for the PRH in Dublin.

PRH3: PNF Registration Update the A&AI Entry

When the PNF registers, PRH should update the A&AI entry with the information in the VES event.

PRH shall update A&AI with all fields from pnfRegistration VES event into all corresponding fields of A&AI entry. See the 5G - PNF Plug and Play wiki

DEVELOPMENT STATUS:

DCAEGEN2-691 - Getting issue details... STATUS

PRH4: PRH Re-Registration Support

PRH support for the Re-Registration Use Case in PNF PnP (for BBS Nomadic ONT PNF Re-registration Use Case). Which fields to compare in mapping field to determine a reregistration PNF.

DEVELOPMENT STATUS:

DCAEGEN2-1059 - Getting issue details... STATUS

API CHANGE:

New field for event publishing on pnfReady topic & pnfUpdate topic enhanced with additional fields as received in pnfRegistration event (a 1-to-1 copy). Was reviewed & agreed with BBS U/C team and change made in code (continuous integration system). Mar 14, 2019

DEFERED TO EL ALTO

PRH1: A&AI New PNF
Schema Adaptation

New A&AI schema adaptations: 5G - PNF Plug and Play (Casablanca carry-over items) 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/Casablanca 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. Change in primary key in A&AI.

Added March 13th 2019 → AAI team got a recommendation from architecutre committee to defer this item to ONAP/El Alto release.

ASSOCIATED DEVELOPMENT:

See task A&AI1 and SO4.
This work is to be covered here: DCAEGEN2-885 - Getting issue details... STATUS

PRH(discuss): Step 37a PNF "Activated" message to ONAP

State Change VES Event (type = State Change)

Old state & New State.

CPE Authentication Notification

BBS U/C is using this flow to "update" ONAP letting ONAP know that the PNF has been successfully been activated.

From VES Event Listener Document:

newState	string	Yes	New state of the entity: ‘inService’, ‘maintenance’, ‘outOfService’
oldState	string	Yes	Previous state of the entity: ‘inService’, ‘maintenance’, ‘outOfService’

A&AI IMPACTS

DUBLIN ITEM	DESCRIPTION
~~A&AI1: A&AI pnf-id as INDEX for PNF~~	[A&AI] Using the pnf-id (instead of pnf-name) as the index for PNF into A&AI. (discussion started in R3, socialized, Contact: Chesla Wechsler ). The URI will change, as a query parameter. Get naming indexing consistency with PNFs and VNFs. Schema A&AI model update. API change in A&AI. No external API impacts. ACTIONS: Inform Clients of break in change & migration. Details: Proposal to Change AAI PNF Entity to use PNF-ID as key Added March 13th 2019 → AAI team got a recommendation from architecutre committee to defer this item to ONAP/El Alto release.

A&AI4: SO support of A&AI creation	[SO] A&AI UI can create an inactive PNF (inactive) A&AI entry. A Service provider might use an inventory system and A&AI UI to create a PNF A&AI entry. In Step #19A instead of EXITING, SO would go into WAIT STATE pending rehydration of RLF w/ pnfReady DEVELOPMENT STATUS: (Completed in ONAP/Casablanca - SO-797 - Getting issue details... STATUS )
A&AI5: SO support for already existing PNF A&AI entry	[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) In Step #19B SO would exit and service creation would continue
MOVED TO R5 EL ALTO
A&AI2: External Manager (EMS/NMS) [ESR]	[A&AI] IP address or association with the External Manager. Is the ESR concept sufficient? https://onap.readthedocs.io/en/beijing/submodules/aai/esr-server.git/docs/ During PnP, the IP address of the External Manager would saved/stored or set by user or by the PNF. Where would that be stored? would it be in A&AI. Information about the External Manager is discovered & stored. Note: The External Manager info is optional LOW PRIORITY

PORTAL IMPACTS

DUBLIN ITEM

DESCRIPTION

Impact on Functional Menus

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.
