    • PFCP enabled SPGW now supports multiple robustness features. This includes detection of user plane failures, retransmission of messages, timeout the transactions. PFCP enabled UPF is under test.
    • Added a helm chart for PFCP-agent. Started to upgrade Accelleran DU/CU images and their Helm chart.
  • CICD & licensing 
    • CI support for Member-only repos.
    • Enforced licensing for Member-only repos using the REUSE licensing tool.
    • Nightly Jenkins Job set up for testing SD-RAN cluster deployment.
    • CD pipeline with Terraform is in progress.
  • Deployed Aether staging central on AWS. 5G enabled UPF is deployed in Aether production. Also we started to enable PFCP to run within Aether Edge on Laptop.
  • We started to investigate the 5G SA Core network and study the 5G specification.

Ambassador Program

  • ONF Ambassadors are actively planning for virtual online events in their respective regions for the coming fall season. We currently have ONF Introductory events planned for Latin America, Middle East, and North Africa commencing in October.
