SO IMPACTS
PnP DUBLIN WORK ITEM | DESCRIPTION |
SO1: Controller Association | [SDC/SO] The PNF controller caused quite a stir in Casablanca, the tension between Design/Platform Model vs Run-Time/Deployment Model. |
SO2: 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: |
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. |
| SO4: SO to support updated A&AI PNF schema | [SO] Support of SO for updated AAI PNF instance model. ASSOCIATED DEVELOPMENT: See task A&AI1 and PRH1. |
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). ASSOCIATED DEVELOPMENT: VNFRQTS - Certificate Authentication for HTTPS/TLS - VNFRQTS-524 - Getting issue details... STATUS DCAE Development for Authentication for HTTPS/TLS - |
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. 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 |
| 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. 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. Change in primary key in A&AI. ASSOCIATED DEVELOPMENT: See task A&AI1 and SO4. |
| 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 |
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. ACTIONS: Inform Clients of break in change & migration. ASSOCIATED DEVELOPMENT: (Jira Ticket needed) |
| 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 |
| 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 |
| A&AI4: 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: (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 |
VID ENHANCEMENTS
PnP DUBLIN WORK ITEM | DESCRIPTION |
VID1: VID Enhancements | WORK ORDER (Optional) – Supporting Work Order. Supported with service specific applications. Inventory systems (optional). Future extension to ONAP. Interface w/ BSS-OSS systems (API). ACTION: Error cases (check if SDC model parameters != A&AI PNF entry) |
| VID2: VID Enhancements | VID A&AI INSTANCE CREATION – (optional) (slide 20/Step 4) – VID supporting Resource Declaration a PNF A&AI Instance creation. Similar flow in eCOMP. |
| VID3: VID PNF Mgmt. Enhancements | VID comes with certain PNF management capabilities. These will be impacted by an A&AI PNF model changes, and VID will have to be updated to support the new AAI Schema change PNF model (PNF-id vs PNF-name) Proposal to Change AAI PNF Entity to use PNF-ID as key |
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. DEVELOPMENT STATUS: PORTAL-490 - Getting issue details... STATUS ASSOCIATED DEVELOPMENT: More details are here - 5G Usecase Impacts on Portal platform |
USE CASE SPAWNS
| XTRA1: 5G RAN Work Flow | Need dedicated 5G RAN Work Flow for PNF Plug and Play (instead of it being part of the VCPE work flow). |
| XTRA2: VNF & PNF 5G Flow | CU w/ DU - New 5G Sub-Use Case. Interleaving w/ Controller association. MODELLING work to lay ground-work (SA/SD, OO, UML) 5G RAN W/F |
