 Description of Use Case / Requirement:

This epic covers the J-release requirements for E2E Network slicing use case in the following tracks.

1. E2E Network slicing Solution
2. RAN Slicing
3. Transport Slicing
4. Closed Loop
5. Carry over testing from Istanbul Release

1. E2E Network slicing Solution

• Slice selection taking into consideration resource occupancy levels
• Dynamic Discovery of Core & RAN endpoints at NSMF
  • M2 update: RAN endpoint in back haul is considered for J-release, Core endpoint discover is a stretch goal
  • M4 update: It can be done in the future release, as more details need to be worked out.
• Activate, Deactivate scenarios support in external RAN NSSMF - Option2
  • RC notes: Merge will be done in future release
• Use case Automation
  • M4 update: Work in progress on the supporting SDK. May be extended beyond J-release

2. RAN Slicing

• Optimizing cm-handle registration with CPS-DMI Plugin to upload yang model
• CPS Integration with SDN-R for RAN Slice allocate and reconfigure scenarios
• CPS-TBDMT enhancement to integrate with NCMP
  • M2 Update: This requirement will be implemented once the Caching is enabled in CPS
  • M4 Update: Will be done in future releases
• CPS Integration Stabilization - RAN Slice activate/deactivate and terminate scenarios
• CSIT for RAN slicing
  • RC notes: Deferred to future release due to a pending bug fix

3. Transport Slicing

• TN NSSMF enhancements according to IETF latest specification
  • M4 update: Will be deferred to next release.
• Implementing the call to OOF for allocateNSSI (to enable TN NSSI reuse) in TN NSSMF
• Implementing the call to OOF for terminateNxi API to deallocate NSSI (to enable TN NSSI NOT terminated even when NSI is terminated) in TN NSSMF
• Transport Slicing enhancement to support IBN based E2E slicing
  • M4 update: Will be deferred to next release
• Closed-loop enhancement in CCVPN to support Transport Slicing’s closed-loop
• CSIT for transport slicing
  • M4 update: Will be deferred to next release

4. Closed Loop

• IBN based Closed loop for Network Slicing
  • M2 Update - ML Prediction MS enhancements will be done as a POC work in this release.
• CPS Integration Stabilization

5. Carry over testing from Istanbul Release
Option-1

• E2E testing for activate/deactivate scenario
  • RC notes: Deferred to future release due to a pending bug fix
• Complete the pending test cases for E2E Slice termination

NSMF driven TN slicing

• Complete the pending testing for activate/deactivate and terminate scenarios
  • RC notes: Deferred to future release due to a pending bug fix
