Code Coverage Reports : Latest reports can be found at the following Link: Projects - O-RAN Software Community (sonarcloud.io).

Mission: E2 updates with first E2APv2.0 support and improvements in registration and subscription interface in xapp frameworks.

Original primary goals: RIC-878 A1 mediator testing in nanobot; RIC-860 xapp testing nanobot enhancements: wider coverage of functionality, e.g., Subscription deletion // RIC-849 Second step of reimplementation of A1 mediator in golang, excl. A1AP-EI  // RIC-714 support for DMS REST interface in addition to DMS CLI // RIC-698 Switch from Redis 5 to Redis 6 // partially done only RIC-704 E2 check, validate and define how various overload and disconnect case are handled, incl. checking highload-results from dawn;  RIC-886 Support two SCTP streams in same association for global (support functions) and functional procedures (ric services);  RIC-916 new reconnect timer in E2 to reject new connect for x seconds; RIC-888 interface so that xApps can only query E2SMs with a given OID; RIC-722 + RIC-867 base support for E2APv2.0 (same level of functionality as before) in e2t, e2m, submgr, and nodeb-rnib; RIC-638 Adapt configuration transfer capabilities as defined in E2AP v2.0; RIC-383 Epic: implement E2AP RESET as per E2APv2.0; RIC-445 SSH container/pod that includes a RIC CLI ; RIC-870 helm3 in default deployment and move ric platform deployment to ric-dep; RIC-815 ric-dep documentation only in ric-dep and it-dep only has references ; RIC-827 support deployment of ric platform in different k8s namespaces to allow two parallel installations // RIC-808 List subscriptions by xApp debug interface; RIC-375 Remove support for ASN.1 (over RMR) based subscription in subscription manager (incl. xapp modifications) // RIC-705 update xappframework for c++ to change in xApp registration  // RIC-906 time series (influx db) wrapper // RIC-642 Add REST subscription support in Python framework

Achieved F release highlights = high-level release notes (2022-05-18) below (note that the release image list is here: link)

• we updated from E2APv1.1 to E2APv2.0 for the existing supported E2 procedures.
• Additionally E2 configuration transfer procedures (in E2 setup and via explicit E2 Node Configuration Update) are now supported.
  
• Enhancements in the handling of E2 disconnect+connect cycles and in SCTP stream handling
• xApps can now query the list of RAN functions by E2SM OID (and nodeb ID)
• The reimplementation of the A1 mediator in golang has proceeded, but is not yet ready and not yet replacing the existing python implementation
• Switch from Redis 5 to Redis 6 - primarily due to Redis 5 EOL
• The ric deployment is now possible without the it/dep repo
• More information in the debug interface of the subscription manager (which had some small adaptations for E2APv2.0, but these changes are not visible to xApps using the E2 subscription manager REST interface)
• a new influxdb wrapper as component stslgo (shared time-series layer "golang")
• bug fixes as per link. Bugs relevant to production (i.e., not test) code: RIC-903 DefaultUser setup fails when authentication is enabled for InfluxDB; RIC-895 missing static route entries for service update messages (from E2T to E2M and back); RIC-889 Subscription Manager Swagger YAML file is wrong; RIC-872 RMR routing statistic data printout crash; RIC-885 sdlgo multi-namespace SDL event namespace filter issue; RIC-880 Wrong date in sdl (C++) rpm spec file; RIC-873 SDLCLI get - writes wrongly results to stderr in success case; RIC-862 xapp-frame-py caching of error code data not happening (was: Python RMR Memory Leak); RIC-869 SDLCLI healthcheck - Redis sentinel status is wrong

For the F release of the near-RT RIC we did only limited integration testing: only the use cases: deploy RIC, deploy xApp and make E2 connection were tested.

Filled in end-of-release checklist : Release criteria checklist - Release F

Status 2022-05-05: From the 28 epics planned (link) we implemented 10 (link). 8 items have been moved out of the F release, e.g, because of implementation delays (link). Incomplete items: 10 (link). Additionally we fixed 18 bugs and small implementation tasks (link)

Code coverage: Code coverage reports (current coverage and list of components that need to set up Jenkins job for auto-generation of the reports as part of CI)

• The primary goal of Non-RT RIC is to support intelligent RAN optimization by providing policy-based guidance, ML model management and enrichment information to the near-RT RIC function so that the RAN can optimize, e.g., RRM under certain conditions.
• It can also perform intelligent radio resource management function in non-real-time interval (i.e., greater than 1 second).
• Non-RT RIC can use data analytics and AI/ML training/inference to determine the RAN optimization actions for which it can leverage SMO services such as data collection and provisioning services of the O-RAN nodes.
• Non-RT-RIC will define and coordinate rApps (Non-RT-RIC applications) to perform Non-RT-RIC tasks.
• Non-RT-RIC will host the A1 interface (between NONRTRIC & near-RT RICs )
• Non-RT-RIC will also host the new R1 interface (between rApps and SMO/NONRTRIC services)

F Feature Scope / Achievements:

• Study & prototype Coordinated Service Exposure (SE)

  • Continue SE contribution building on the manual approaches already studied/completed.
  • Create/apply K8S configurations to isolate platform services and rApp microservices, then configure controlled secure access between service
  • Prototype CAPIF compliant API for Service/rApp registration/discovery, and service provider/consumer registration/configuration

• Data Management & Exposure (DME):

  • Pre-spec O1 PM via pre-spec R1 DME demo
  • Configure & connect to PM data - collected by SMO (ONAP)
  • Collect, Filter & Coordinate Delivery of PM data from DMaaP/Kafka to rApps over R1 (ICS)

• General activities

  • Continue to provide spec-compliant implementation of A1-Policy & A1-EI functions
  • NONRTRIC repo re-org
  • Continue to integrate and deploy SMO/NONRTRIC platform/rApps in OSC integration env.
  • Continue to expand NONRTRIC test platform & testsets
  • Show various versions rApps implemented/deployed as holistic “Automation Compositions” (ref ONAP ACM)
  • Continue to provide & integrate strawman rApps to comply with OSC RSAC integration usecases.

F release maintenance source code, container images, and deployment instructions

TODO

Code coverage: To be planned as UT framework is not available to provide code coverage.

Primary Goals:  

The O-DU Low F release adds support for Massive MIMO, URLLC and it is based on the commercial FlexRan 21.11 release. This release is an incremental improvement over the E-maintenance reelase code released on March of this year and that still needs to be integrated with the RSYS O-DU High code.

The F release can be used for end to end testing and it is based on the E maintenance release that was used for the 2021 November US O-RAN Plugfest and tested in conjuction with 2 stack partners and 2 different Test equipment vendors. The Front Haul Interface was also tested for compliance using Keysight's Front Haul Test equipment.

Container images and deployment instructions TBD

E Release Feature Scope: 

O-DU Low  E maintenance release was provided in March, 2022 and it is based on the code used in the November 2021 US O-RAN Plugfest. There are additional changes in the vendor specific portion of the API to support Massive MIMO and URLLC.

Since the code was deployed in the US O-RAN Plugfest using the commercial versions of the stack partners O-DU High code, the open source version from the partners need to be integrated as well. 

The validation done prior to the release used the timer-mode and the test-mac to check all the new features.

Provided O-DU Low E-Maintenance Release on March 2022 to the O-RAN gerrit repo, documentation was updated. Binary blobs for the FlexRan L1 and testmac codes were also provided in github in March.

E release source code, container images and deployment instructions

Source code and documentation including deployment instructions have been provided to the O-RAN documentation siite

Primary Goals:

• Keep alignment with latest O-RAN specifications (O1, E2)

F Feature Scope:
