5G use case - Answers for Arch Qs

1

Would the use case(s) require multi-site support?

Yes

Site = Node (PNF or ≥1 VNFs)

e.g., Radio Unit

e.g., Radio Control Function

2

Would the use case(s) require multi-region/multi-domain/federation support?

1. Multi-region (= multiple ONAP instances?): No

2. Multi-domain: Yes

   1. lifecycle of ≥1 RAN domains

   2. lifecycle of ≥1 slice instances

   3. lifecycle of RAN+WAN+EPC domains

   4. .....any other?

3. federation (=multiple operators): No

3

Would the use case(s) require Multi-national support?

Maybe – minimal impact from this use case to support multi-nations deployment

If Operator using ONAP instance across national boundaries, Yes.

e.g., multiple Operating Companies? No

No, if multiple ONAP Instances?

4

Do we need to consider enhanced networking features (e.g., underlays)?

Not applicable

5

Can individual use cases be built from same components? (common APIs/models)

Yes?

1. what "same <onap?> components"?

2. what existing APIs/Models?, e.g., generic VNF model?

6

What are the new challenges from the first set of use cases?

1. Support a hybrid network consisting of PNF & VNF across RAN, WAN and EPCore
   
   

2. Support CRUD on Network Slice(s)

3. Design studio (SDC) enhancement
   
   

   1. Component models: e.g., RAN VNFs, Core VNFs, PNFs, etc..

   2. E2E model(s): e.g.,service chain (tosca) topology

   3. policy model(s)

   4. ...other?

4. AAI enhancements to capture topology & inventory. 

5. SO / App-C / DCAE / Policy enhancements to support for PNF and slice lifecycle management, slice deployment and management.

6. DCAE / Policy enhancements to support open framework for near-real time network optimization, conflict resolution during design time as well as run time across multiple microservices.

7. OOF enhancements to support multi-cloud and 5G network optimizations.

not part of R1 use cases (ref: Use Case: VoLTE(approved))

What technical debt have you identified?

See above

Clarify business drivers and capabilities of the use cases

5G and network slicing are emerging technologies that are complex and distributed.  Multiple service providers are getting ready to deploy.  his will help 5G technology vendors to understand ONAP requirements and deliver PNF / VNF capabilities that can be managed using ONAP.

This use case is expected to:

Release 2 Goals:

1. Enhance ONAP platform capabilities for supporting hybrid network consisting of PNFs & VNFs in a multi-domain (RAN vs WAN vs EPC) scenario

2. demonstrate use of ONAP platform to realize following:

   1. (simple?) A planned list of 5G Nodes are on-boarded into ONAP, and ONAP configures the Nodes to the level they are ready to handle traffic. ONAP begins to actively monitor and manage the nodes.  

   2. CRUD operations on RAN-only slice(s) and RAN-to-EPC slice(s)

   3. Optimizations

Future Releases ....??

What are the functional commonalities between the use cases? Are there generic elements where we should focus?

See answer to question 6 above 

which (other?) use cases?

• Use Case: VoLTE(approved)

• ...other?

10

Clarification of requirements.  For instance, you call out PNFs. What level of PNF support do you need for R2? Also, what are the requirements driving the need for PCE and NAI components?  Could those be satisfied by existing components?  If not, please clarify why not so that we can discuss how those components fit with the existing components and the rest of the architecture

N/A - Seems targeted for the Enterprise vCPE case

11

Discuss key features for R2.  From what we can tell, multitenancy/slicing, WAN/connection types, and PNF support seem to be required.  Are there others?
