Demo: GitOps-Based Automation for Distributed NFs Reconfiguration in Cloud-Native O-RAN
O-RAN disaggregation introduces flexibility in deploying Central Units (CUs) and Distributed Units (DUs) as independent network functions (NFs) connected via midhaul (F1 interface). In cloud-native deployments, multiple CU instances may coexist across clusters, each with varying compute load and network distance. In current practice, CU–DU associations are typically static and do not adapt to changing runtime conditions, making it difficult to apply consistent, timely configuration changes when a CU becomes overloaded. This demo presents a GitOps-based automation framework for runtime reconfiguration of distributed NFs in cloud-native O-RAN. The framework continuously collects NF telemetry and evaluates reconfiguration triggers, applying declarative updates via GitOps workflows to ensure consistency, traceability, and rapid propagation across clusters. As an illustrative scenario, we demonstrate CU–DU coordination under compute stress: when a CU instance becomes overloaded, the system automatically initiates reconfiguration or DU reassociation to an alternative CU. During the demo, attendees will observe live telemetry, configuration commits, and protocol traces showing CU-DU reassociation in response to induced load, illustrating a practical realization of automated NF reconfiguration in cloud-native O-RAN.
