Near-Real-time RIC X-APPs (RICAPP)

Near-Real-time RIC X-APPs (RICAPP)

Primary Goals:  Expand the community working on open source xApps for O-RAN SC.  Update and maintain the existing xApps to latest releases.

Enhance the set of open source xApps in support of the RSAC use cases (traffic steering, network slicing) and add new xApps.

New RUST framework xApp hw-rust will be added in this release. 

H release plan:

  • New HW-Rust xApp to support RUST framework.

  • New ad-cell xApp to detect cell level anomaly.

  • RC xApp - GRPC interface support on RC xApp

  • Bouncer xApp - RIC Benchmarking new features addition.

  • KPIMON-GO xApp – New Version

Completed Epics:

RICAPP-216: Bouncer xApp upgraded to E2AP 2.0, E2SM KPM 2.0, E2SM RC 1.0.3

RICAPP-215: Anomaly Detection xApp (H-Release) - listens to RMR port and expect A1 policy from non-RT RIC & Process A1 policy message.

Bug:

RICAPP-214 OSC RIC - e2mgr X1 Configuration Update problem - Moved to RICP

Epics moved to next release.

  1. RICAPP-212: Hello World Rust Xapp initial release

  2. ad-Cell xApp

  3. RICAPP-211: RC Xapp - upgrade to E2SM-RC-2.0

H release highlights/accomplishments:

Near-Real-time RAN Intelligent Controller Platform (E2 Interface) (RICPLT)

Near-Real-time RAN Intelligent Controller Platform (E2 Interface) (RICPLT)

Original primary goals based on contributions from Nokia, Samsung, HCL, Capgemini, Parallel Wireless, Alexandre Huff (UTFPR) and Abhijit G:

  • We will deprecate the RMR-based E2 subscription interface and H-release xApps need to use the REST based interface already supported by the the C++, go, and python xApp frameworks (RIC-375). The subscription manager should handle subscriptions for failing xApps (RIC-929) and provide a callback on subscription delete success/failure (RIC-928). We plan to implement the RIC subscription delete required procedure (RIC-851)

  • Update to newer golang version of all components (RIC-881)

  • We will develop a CRD, i.e., a K8S operator on top of the DMS REST API to simplify xApp deployment (RIC-715). Also the DMS Rest interface gets the missing delete API (RIC-954). RIC-717 allows to deploy multiple cooperating xApps together.

  • On E2 side we will implement the E2 Reset procedure from RAN to RIC (RIC-949) and the RIC Subscription Delete procedure (RIC-851). We also implement robustness improvements (RIC-932 for reconnect cases) and troubleshooting improvements (RIC-813, RIC-814).

  • There's work planned to deploy the kserve-based model provisioning from the AI/ML project into the RIC platform (RIC-955)

  • The xapp frameworks for Golang (RIC-930), C++ and Rust (RIC-951) will get some enhancements that are already implemented in the other languages, incl. support for xApp registration in the xapp-framework-cpp (RIC-705).

  • E2T (RIC-813) and E2Mgr (RIC-814) support dynamic changing of log levels for better troubleshooting

  • RIC-953 A1 testing improvements and bug fixes

  • Added to plan during H:

    • Support for policy status notifications in A1 (RIC-973 (incl. RIC-975))

    • Faster timeout in SCTP heartbeats (E2) (RIC-976)

    • IPv6 support in RMR (RIC-985)

 

Achieved H release highlights = high-level release notes (2023-06-20) below (note that the release image list is here: link)

  • E2 reset (from E2 node to RIC), E2 subscription delete required, A1 policy status notifications

  • Preparation of feature for I release, e.g., include xApps in subscription delete required decision

For the H release of the near-RT RIC we do only limited integration testing: only the use cases: deploy RIC, deploy xApp, make E2 connection, get list of A1 policies has been tested.

Filled in end-of-release checklist: link

PTL: @Thoralf Czichy

Status 2023-06-20: From the 23 epics planned (link) we implemented 11 (link). 12 items have been moved out of the H release, e.g, because of implementation delays (link). Incomplete items: 0 (link). Additionally we fixed 10 bugs and small implementation tasks (link)

H release source code, container images and deployment instructions

The list of container images for the  release (link). A demo video for the H release deployment is available at the top of the demo page and shows

  • how to deploy the near-RT RIC platform,

  • compile connect the E2 (e2 node) simulator from the OSC simulator project and

  • compile the hw-go xapp from the xapp project and use the dms_cli to deploy it and check the E2 subscriptions the xApp created.

    • all components exposing http northbound are reachable by FQDN (https port 443)

    • the OAM-Controller components interfacing with the network can be reached also by FQDN (VES-http: 443, SSH-Callhome: 4334, TSL-Callhome 4335)

  • Add a FlowManagement Component

    • which includes examples for ONAP-VES, StndDefined-VES with 3GPP-Body and StndDefined-VES with WG4-OFHM-body
