Meeting recording listed to the right.

Went through Release "D" Control Loop:

  • Alignment of DMaaP Topics across projects
  • Confirmed proposed YANG for O-DU is being analyzed by the O-DU team, should have an answer by next weeks call.
  • Confirmed Config was sent to O-RU team, ODU Team needs to know how to initiate pairwise testing
  • Reaching out to contributors for E2SIM modifications for Traffic Steering Use case
  • David Kinseywill Reach out to OTF team for OTF E2SIM integration at the same time
  • David Kinsey will work with Rittwik Jana to work with Taiwan University to see how best to use them for Integration Project. They likely will not have a FHG in their environment and therefore are missing O-DU functionality for Hybrid or Hierarchical support models to the O-RU.
  • SMO discussion was deferred as Mahesh had another meeting commitment. Nothing major pending.
