SMO Lite - An Integrated Open-Source SMO Deployment

https://lf-o-ran-sc.atlassian.net/browse/INT-170

it/dep repo: https://gerrit.o-ran-sc.org/r/gitweb?p=it/dep.git;a=shortlog

• Provide consolidated SMO install charts & scripts to deploy a ready-to-use comprehensive SMO deployment/installation.

• Ensure charts/scripts are as dis-aggregated/modular as possible to support reuse, extension & customization.

• Ambition/Maturity/Stability/Security levels are targeting demo/developer/experimentation type deployments. Additional work will be needed for deployments with more rigorous requirements

• Tidy up & consolidate existing smo-install+ONAP-OOM, nonrtric+ONAP-OOM, OAM, ranpm, teiv charts & scripts into a single deployment - reusing the same/common underlying platform functions (e.g. kafka/strimzi, keycloak, influxDB, etc)

• Examine how to include Nephio deployment charts & scripts

• Examine how to include AIMLFW project charts & scripts

• Examine how to include SMO project charts & scripts

• Make pre-build charts available for reuse. (Avoid always needing to rebuild charts - Depending on deployment requirements)

• Examine if an SMO-Lite deployment can be made available in OSC labs (e.g. WinLab)

From ONAP: Extends ONAP OOM charts & scripts, so everything in ONAP can be turned on & will work.
The main functions we need initially are:

• SDNC 

• A1 Policy Manager (& SNDC A1 Adaptor)

• ACM (used by rApp Manager)

• VES Collector

• Policy framework (including OPA PDP)

• NCMP & CPS

• … anything else in ONAP can be enabled – will work out-of-the-box.

From NONRTRIC-RANPM: Full toolchain for file-based RAN PM, with filtered DME jobs available for rApps

• O1-PM File collector

• File Parser -> JSON

• Filtered JSON -> InfluxDB

• Filtered JSON -> DME producer

From NONRTRIC:

• Information Coordinator (non-R1-Compliant DME coordinator)

• Service Manager & Catalogue (nearly-RI-Compliant SME functions)

  • OSC CAPIF for service registry (Also studying ETSI OpenCAPIF)

  • Kong API gateway

• “DMaap”-Adapter: Generic Kafka->DME producer (doesn’t use DMaaP anymore )

• rApp Manager

  • Supports a custom rApp package format

  • Uses ONAP ACM for composite-rApp LCM

  • Auto integration with SME & DME

  • rApp Catalogue

• Topology Exposure & Inventory (TEIV) functions

From Nephio: Still working on this, but likely everything since Nephio charts are fairly stand-alone.

• Skeleton O2-DMS & O2-IMS (FOCOM & NFO)

• Porch, Kpt, O-RAN operators etc.

Common/cross-cutting functions/utilities:

• Strimzi Kafka (cross namespace support added)

• Keycloak

• InfluxDB & Minio

• Postgres (&PostGIS)  

• Red Panda

• Prometheus & Grafana (TBC)

• Logstash (TBC)

Not yet considered: (ToDo)

• Tacker & OpenMSA   (No idea how these should be installed. No K8s charts available?)

• AIMLFW functions (Currently installs standalone alongside SMO)

  • Needs some integration – eg:

    • Uses some common functions (esp kafka, DME & SME)

    • Provides a KServe environment for ML-enabled rApps

• Others – TBC

Out-of-scope: … but should be possible along-side

• Core network function

• RAN network functions / simulators

• Near-RT-RICs & xApps
