Guilin Planning - Architecture

Moderator: @Chaker Al-Hakim

Great collaboration between the Subcommittees !

OOM Daily gating: https://gating-results.onap.eu/results/

Wiki link

•  Wiki, RTD, ONAPDocs - a lot of information about ONAP from different sources

#1 Request to the ONAP Community to review the different templates:

• Project Architectural Review Requirement and Process (draft)

• Guilin Reviews

#2 Define the scope/role of all the Documentation tools and potential synergy i.e. integrate this “ONAP directory” in readthedocs or www.onap.org, not as a separate landing site

ETSI/CNF - Container Modeling

Moderators: @Andy Mayer, @Hui Deng

#1 ETSI NFV Container Architecture and Modeling@Ulrich Kleber

VNF can use VM-s or containers. 

CNF is a _Cloud Native_ NF what is a VNF built with the Cloud Native principles in mind

ETSI-based CNF support is compliant to IFA029&IFA040 (publication expected in May)

Additional information shared by @Thinh Nguyenphu :  ONAP-ETSI Alignment Workshop (IFA040)

#2 CNTT RA2 @Tom Kivlin , @Gergely Csatari

Possibility to run NF on top of what it is defined in RA2 / K8S 

No conflict/overlap between what ETSI CNF defined and CNTT RA2 (K8S)

CNTT Roadmap

Open

#3 CNCF TUG (Lei Wang)

• Cloud Native Thinking for Telecommunications

• Deploying Cloud Native Network Functions in a telecom service provider ecosystem

• Cloud Native Principles gitbook

• CNF Conformance (github)

• Conformance Test Categories Documentation

• CNF Conformance (deck)

• Platform Conformance Test in alignment with CNTT RA2

#1 ETSI approach seems to generalize the capabilities of the container infrastructure layer and may limit the use of the full capabilities of Kubernetes - no recommendation in IFA029.

#2 How to refer CNI in the descriptor?

Normally no need to have CNI reference in the pod manifest - K8S should evolve to support it but there is currently no solution.

#3 Different approaches for CNF Modeling - no conclusion yet from CNCF about the best approach 

Open

#4 How can we stay align between ETSI, CNTT, ONAP, CNCF, OVP PH2, etc?

#1 Get Helm Chart sample from ETSI

#2 Upload Lei Wang's presentation (done)

ETSI/CNF - CNF Orchestration over StarlingX 3.0 Demo

Moderator: @cl664y@att.com

Speaker: @Bin Yang

•  cFW - POC in progress based on ONAP MultiCloud project - Source code available here

• What API is used in VID? VNF API or GR API? Does it make any difference? What about that override.yaml - is there an example available? VNF/VF API to instantiate the deploymen

• No development yet related to fault and performance monitoring of the CNFs. Targeted for Guilin.

•  Dummy heat template is temporary for now as we did not want to make any major changes to SDC and SO.  In R7, we intend to make Helm as first class citizen.  Until R6, Helm charts are hidden as artifacts under Dummy HEAT template.

E2E Network Slicing- Session 1

Moderators:

@LIN MENG @Swaminathan Seetharaman

1. The overall requirements for E2E Network Slicing use case in Guilin release was presented. This covered:

• New slice lifecycle operations to be supported. eg: slice modification, slice termination

• Expansion in scope of E2E network slice to include RAN and Transport

• Realization of NSSMF (Core/RAN/Transport) within ONAP, ONAP should also support NF set up and NF configurations under this condition

• ONAP as NSMF connecting to external RAN NSSMF and Core NSSMF

• KPI Monitoring, Closed Loop and Intelligent Slicing

• Improvements to Frankfurt content

 2. User Operation Guidance for E2E Network Slicing Use case for Frankfurt release was presented. This covered:

(a)    ONAP components required for the use case, and the setup

(b)    How to create the associated design artifacts

(c)     UUI actions

 3. Questions asked:

• How is Core NSSMF intended to be realized within ONAP?

• How will a service be orchestrated by ONAP wherein part of the service only is within ONAP scope, whereas NSSMF within ONAP may be controlling the associated slice sub-net.

• Details of modeling aspects and enhancements.

• Are external domain controllers foreseen to be used for the domain-level actions?

Action Items

1. Elaborate the modeling requirements and take it to the Modeling Sub-committee.

2. Prepare further details, and illustrative flows showing interactions & APIs, including interaction with external domain controllers

Guilin Planning - OOM Proposal

Moderator: @Eric Debeau

Speaker: @Sylvain Desbureaux

Review of OOM Guilin Release proposal 

• Continue the removal of harcoded credential

• upgrade of open source version recommended by SECCOM

• Allow the choice of subcomponents

Some proposals with help of projects:

• All logs to STDOUT

• Certificates

• Crash well when Issue (and not "wait for I don't know" or exit with status 0)

• AAF integration must be settable to off

• MSB integration must be settable to off

Tentative / PoC

• Make Ingress default deployment

• Make Deployment with storage class default deployment

• check storage asked for PVC is consistent with actual deployments

• Service Mesh PoC continuation

• All pods have requests/limits

• request/limits bad values hunting: use only 10 vCPU while 92 vCPU are required, RAM may be divided by 3

#1 Assess the impact of upgrading to the version suggested by SECCOM? Does it require any architecture change or is it transparent for the component (only Helm Chart modifs)?

Guilin Planning - Integration priorities

Moderator: @Eric Debeau

Speaker: @Morgan Richomme

• ONAP cross-project system integration

• CI/CD

@Morgan Richomme also requesting PTL to realease as soon as possible. Do not wait R4 to update OOM when new image is available

•  Integration Guilin Release proposal

X-projects

• Maintain java11

• create python3.8 baseline image

Repositories

• Adopt the approach to create a repo for new use cases / simulators

• Add linters to all the new repositories

• Add new linters (tobot, bashate, rst)

E2E Network Slicing- Session 2

Moderators:

@Swaminathan Seetharaman@LIN MENG

1. "RAN and Transport Slicing" proposal and scope for Guilin release was presented. This covered:

• Overview of RAN Slicing, scope and assumptions for Guilin release

• RAN NSSMF within ONAP, as well ONAP acting as NSSMF interacting with an external RAN NSSMF

• Overview of Transport Slicing, based on TSCi (IETF), scope for Guilin

• TSCi information modelz

• Interaction between RAN and Transport Slicing, different deployment scenarios

2. "KPI Monitoring, Intelligent Slicing and Closed loop" proposal and scope for Guilin release was presented. This covered:

• KPI monitoring by slice tenant/operator (via portal)

• Three SON scenarios for Closed Loop Automation and Intelligent Slicing namely:

1. Slice resource optimization: Guilin: simple close loop for single NSI scenario; Beyond Guilin: Cross- Slice Scenario

2. KPI adherence optimization (KPI Guarantee): (Guilin: simple close loop by introducing AI model. Beyond Guilin: cross-interaction with (1) also)

3. Service experience optimization (SLA Guarantee, QoE based) (Beyond Guilin)

3. Questions asked:

• Are the data models taken from IETF drafts? (Data model details are work-in-progress in IETF, we are closely tracking the developments)

• Will a new SO adaptor be developed for connecting to external TN NSSMF in future, or can existing adaptor be extended? (Intention is to reuse existing one, however, it is under discussion)

• Are we aligning to O-RAN? (Yes, we are having regular interactions with the O-RAN team, intention is to align with O-RAN as much as possible, starting with Guilin release itself).

• Are we considering data from all network segments? (Under discussion)

1. Elaborate the details of Guilin scope with respect to the modeling and interface aspects.

2. Prepare flows for RAN <-> Transport interaction, and details of alignment with O-RAN.

3. Elaborate details of data collection and analysis to be done.
