SO IMPACTS

PNF PnP FRANKFURT WORK ITEM

DESCRIPTION

SO1: Building Blocks

Refactor BPMN workflow. Clean up work previously done in R4.

Migrate existing workflows to existing building blocks.
SO-2556 - Getting issue details... STATUS

Need to sync on the VID implementation of 5G VID Instantiation/orchestration.
VCPE also wants to use these building blocks, but a fully generic solution is desired and targted.

 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. 

OPEN:  cfg assign/cfg deploy dependent on code being created by other contributors. converted existing PnP WF to make it aligned with R5 need to include cfg steps. (Missing some code). (Open point)

DEVELOPMENT STATUS:

Stretch goal in Frankfurt release.

AssignPnfBB

  • Responsibility: Creates PNF entry in A&AI
  • Makes a link in AAI between service entry and PNF entry
  • currently implemented in CreateAndActivatePnfResource.bpmn

WaitForPnfReadyBB

  • Responsibility: Waits for "PNF ready" event sent from PRH to DMaaP
  • Currently implemented in CreateAndActivePnfResource.bpmn

ConfigAssignPnfBB

  • Responsibility: Runs config assign via CDS
  • Currently implemented in ConfigurePnfResource.bpmn

ConfigDeployPnfBB

  • Responsibility: Runs config assign via CDS
  • Currently implemented in ConfigurePnfResource.bpmn


SO PNF PNP migration is being documented: https://lf-onap.atlassian.net/wiki/display/DW/PNF+PnP+workflow+migration+to+Building+Blocks

The JIRA to track progress: https://jira.onap.org/browse/SO-2556.

Lukasz Grech and Lukasz Muszkieta (Nokia) are leading the SO changes related to migration of PNF PnP sub-flows (sub-Processes_ to building blocks.

This link is about the current (Dublin + El Alto) implementation: https://lf-onap.atlassian.net/wiki/display/DW/PNF+PNP+workflow+-+current+implementation

The SO BPMN code can be found at CreateAndActivatePnfResource.bpmn.
This is where the implementation is stored today.

Also refer to the following topic in Gerrit: pnf_bb

https://gerrit.onap.org/r/#/q/status:merged+project:so+branch:master+topic:pnf_bb

This is where other changes expected for the PNF PnP BBs are expected to be added.

A few building blocks will be created in R6 (expected by end of February 2020).

The currently available workflows dealing for PNF PnP can be seen at the PNF PnP test-cases descriptions in the ONAP Integration project.

VID IMPACTS

R6 ITEMDESCRIPTION

VID1 Migration of Sub-worksflows

(Post-poned to R7)

Migration of existing PNF PnP sub-workflows to a new BB approach (probably we will be creating 4-5 new BBs).

VID Impact:

Within “old” VID macro orchestration pages, a special field to provide a pnf-id parameter (shall be actually called “correlationID” or “PNF correlationID”) has been displayed under the following conditions:

  1. Service Model contains a PNF resource type.

When we migrate to BB approach, we`d keep the possibility to provide this parameter (PNF correlationID) to the SO API call as input.

How this will change with SO/BB approach, and with new VID GUI targeted at macro (GR) flows – we`d see exactly, after we execute some tests with new VID UI, and updated SO PNF BB code.
We`d have to check, what capabilities and conditions could be applied to display and process this “PNF Correlation ID parameter”.

Can the same BBs could be re-used in “standard” vCPE use-case.
We`re looking at a generic solution, and we`d probably display this additional field, when we figure out, that there is a PNF resource used in a Service Model.

In R6: only accessible via SO API not the VID GUI, E2E tests prepare environment cover case w/ SO API.

CONTROLLER IMPACTS

PnP R6 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 R6 Frankfurt Work ItemDESCRIPTION



BBS Event Processing Micro-Service

PnP R6 Frankfurt WORK ITEM

DESCRIPTION

PRH(discuss): Step 37a PNF "Activated"

message to ONAP

BBS event processing micro-service.

(Being done by the BBS U/C team)

Post-poned to Rx

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’

R6 - No Changes. BBS will test what was there, will do re-test in R6.

A&AI IMPACTS

R6 ITEMDESCRIPTION
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
A&AI3: Cloud Home Server (A&AI)

[A&AI] Tracking the Cloud Home Server (CLLI, Cloud ID); is the association with the COMPLEX Object sufficient?

How-To: Register a VIM/Cloud Instance to ONAP


LOW PRIORITY

A&AI / Model

MODELING

[A&AI] GeoLocation information for the PNF reported via pnfRegistration VES Event

This will ONLY be modeling work in R6, functionality it moved to future release

MODELING WORK ONLY

A&AI4: A&AI pnf-id as INDEX for PNF

CANCELED

[A&AI] New A&AI schema adaptations: discrepancy between PNFs and VNFs; VNFs are identified via VNF-ID (UUID), and PNFs - via PNF-name. 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).

July 31th 2019 → AAI team has cancelled this request (redacted).

CANCELED

MODEL IMPACTS

R6 ITEMDESCRIPTION
Model

[Modeling] GeoLocation alignment in Modeling with RFC 6225 and the PNFD, A&AI schema, and SDC AID Data model.

(Sept 5) "Place" object (off of the Root) platform ONAP info-model. GB922 Location standards

Latitude/ Longitude / Altitude (RFC 6225) > TMF GB922 > ONAP > Complex & Place object.

LOW PRIORITY (Nice to have)
