Implementation of Hybrid QoS-Aware Data Radio Bearer in 5G Networks

In Fifth-Generation (5G) wireless networks, Quality of Service (QoS) flow management supports diverse applications with heterogeneous QoS requirements, including latency-sensitive and high-throughput services. 5G architectures adopt a flow based QoS framework, where QoS flows are mapped to Data Radio Bearers (DRBs) to...

PRO-RAN: Processor-Level Characterization of Open RAN Centralized and Distributed Units

A controlled characterization framework that evaluates independently deployed CU and DU functions under matched hardware and traffic conditions and identify distinct CU and DU execution characteristics and motivate function-specific processor analysis and optimization is described.

ADORN: Adaptive Drift handling for Open RAN using Reinforcement Learning

Experimental results show that the proposed Q-learning-based adaptive retraining approach effectively reduces retraining overhead compared to greedy and random baselines, while maintaining system performance within predefined limits.

A YANG-Grounded LLM Agent Supporting Multi-Vendor OpenROADM Optical Transport Networks

This paper presents an LLM agent that extends the Optical Network Robotic Automation Platform with YANG-Grounded Agentic Retrieval-Augmented Generation (RAG), and serves as the first instantiation of a pipeline whose YANG-aware components apply to other open standards built on YANG and NETCONF.
