The OAM project focus on the following topics:

Provide complete implementation for OAM functions (FCAPS).

Target

  • support of O-RAN WG10 VES message bodies
  • update of OAM-Controller to ODL version Sulfur
    • Note: team is discussion the possibility to switch from Java11 to Java17 - discussion ongoing
  • update to keycloak version 18
  • even more secure keycloak configuration
  • there is a request for a "bare-metal" deployment which is not in scope of O-RAN, but still useful - also for development and module test
  • support of AI/ML based on RSAC and other input.
