Jakarta Release Updates ----------------------- In Jakarta release, the following aspects are covered: 1. **E2E Network Slicing Solution** - Slice selection based on resource occupancy level. With this enhancement, NSMF/NSSMF is able to monitor and update resource levels at NSI/NSSI level. OOF returns the solution for NSI/NSSI selection based on the criteria. In case of shared scenario, NSI/NSSI can be shareable only if sufficient resources are available in the network. RAN NSSMF’s resource occupancy is considered for this release. Resource occupacy of Core and TN NSSMFs will be considered in future releases. - Dynamic Discovery of Core & RAN endpoints at NSMF. NSMF discovers the RAN endpoints for back haul dynamically at the time of slice allocation/reuse and feeds them to TN NSSMF. Implementation will continue in the next release. RAN endpoints in backhaul are considered for J-release. Discovery of fronthaul, midhaul and core endpoints will be covered in future releases. - Activate, Deactivate scenarios support in external RAN NSSMF - Option2. Note that instantiation and termination are supported in Istanbul release. - Use case Automation. Test automation for slicing use case in phases for manual configurations. Work will continue beyond Jakarta release. 2. **RAN Slicing** - Optimization of cm-handle registration with CPS-DMI Plugin for RAN NF intances to upload yang model. - CPS integration with SDN-R for RAN slice allocation and reconfiguration scenarios - CPS-TBDMT enhancement to integrate with NCMP, where CPS Core is invoked via NCMP from TBMT for RAN Slice configurations, i.e., NCMP endpoints are used in place of CPS Core. CPS Core is directly invoked from TBDMT in the previous release. This requirement will be implemented once the Caching is enabled in CPS in future releases. - CPS integration stabilization for RAN slice activate/deactivate and terminate scenarios. Validation and bug fix for CPS integration of RAN slice lifecycle. - CSIT for RAN slicing 3. **Transport Slicing** - TN NSSMF enhancements according to IETF latest specification. The implementation of this enhancement will be deferred to next releases. - OOF involvement in TN slice reuse and terminate scenarios - Implementation of the call to OOF for allocateNSSI to enable TN NSSI reuse in TN NSSMF - Implementation of the call to OOF for terminateNxi API to deallocate TN NSSI (which may not be terminated even when NSI is terminated) in TN NSSMF - Transport slicing enhancement to support IBN based E2E slicing (Covered in CCVPN use case). The imlementation of this enhancement will be deferred to next releases. - Closed-loop enhancement in CCVPN to support Transport Slicing’s closed-loop (Covered in CCVPN use case). - CSIT for transport slicing. This requirement will be done in future releases. 4. **Closed Loop** - IBN based Closed loop for Network Slicing. This enhancement makes use of intents and Machine Learning models for closed loop. ML prediction microservice enhancement is done as a POC work in Jakarta release. - CPS integration stabilization, which validates and enhances CPS integration for closed loop. 5. **Carryover tests from Istanbul release** - Option-1 (internal NSMF, NSMF and NSSMF) - E2E testing for activate/deactivate scenario - Pending test cases for E2E Slice termination - NSMF driven TN slicing - Pending testing for activate/deactivate and terminate scenarios - Bug fixes and tseting for Core slicing - NF instantiation issue with same NSST - Multiple non-share Core slice creation issue Impacted Modules for Jakarta Release ------------------------------------ - **SO**: Requirements below are identified for Jakarta release and have impacts in SO component: (1) Core, RAN Endpoints dynamic discovery at NSMF (2) TN NSSMF model enhancements according to IETF latest specification (3) Use of Optimization solution (OOF) in allocateNSSI, deallocateNSSI in TN NSSMF (4) Bug fixes/enhancements of carryover test cases from Istanbul release (5) Activate, Deactivate flows support in external RAN NSSMF for option 2 - **OOF**: OOF component has an impact for the requirement below: (1) NSI/NSSI Selection enhancements based on resource occupancy levels - **DCAE**: The requirements below are identified for Jakarta release and have impacts in DCAE component: (1) Slice selection taking into consideration of resource occupancy levels (2) CPS integration in closed loop – This was done in I-release. Expecting minor enhancements in Slice Analysis MS once after the other components impacts w.r.t CPS integration and E2E testing are completed. (3) IBN based Closed loop for Network Slicing - This will have impact in E2E Slicing closed loop and TN Slicing closed loop. - **CCSDK**: The equirements below are identified for network slicing use case in Jakarta release and have impacts in CCSDK component. Most of these requirements fall under the category of CPS integration.

Test cases are classified into 5 tracks: E2E network slicing, RAN NSSMF, TN NSSMF, Closed Loop and carryover testing. Details of the test cases can be found at: `E2E Network Slicing Tests for Jakarta Release `_ and its child wiki pages.
