ONAP Network Slicing Next Steps 5 G Use

ONAP Network Slicing Next Steps 5 G Use Case Team - Borislav Glozman (Amdocs) Apr, 2019

Current state of affairs • A proposed modeling high level example was demonstrated on ONAP committees F 2 F modeling meeting. It is based on current modeling capabilities in SDC. • This example can be enhanced with more details, properties etc. • This example model can be used as a trigger for requirements to support Network Slicing in SO, A&AI, CCSDK, CDS, OOF, VID, Multi. Cloud, Policy, DCAE • Shared services concept that is needed for Network Slicing is still discussed in Modeling subcommittees 2

Example of 5 G e. MBB Network Slice Segment modeling • Example e. MBB NSS consists of 5 G-RAN-NSS, 5 GC-NSS and TRANSPORT NSS. e. MBB-NSS 5

Example of RAN NSS modeling • Example high level 5 G RAN NSS consists of DU (as a Service), CU-CP (as a Service), a dedicated CU-UP, and virtual links between them. • There also External Connection Points. 5 G-RAN-NSS 6

Example of 5 G Core modeling • Example 5 GC NSS consists of 5 GC-CP-SVC, 5 GC-UP-SVC and virtual links between them. • There also External Connection Points. 5 GC-CP-SVC 5 GC-UP-SVC 7

Network Slicing in El-Alto release • Pending: - Agreement on modeling direction – Nested Services/Allotted Resources/Both - Availability of v. RAN / RAN simulators (possibly Open. Air. Interface, RAN Simulator (RAN-Sim) extension) - Availability of 5 G Core components VNFs/simulators - Modeling of transport between RAN and Core network slice subnets - Discussion and analysis of requirements for • • • SO A&AI OOF Multi-Cloud CDS CCSDK - Commitment of development resources in the mentioned components 8
