From Automated to Autonomous: Hierarchical Agent-native Network Architecture (HANA)
Quick Answer
The proposed Hierarchical Agent-native Network Architecture (HANA) enables Level 4/5 Autonomous Networks by integrating self-aware agents and a Dual-Driven Orchestrator, achieving an 86% reduction in Mean Time to Repair (MTTR) during congestion in a 5G Core environment.
Key Points
- HANA enables high-level autonomy through a reference architecture.
- The Dual-Driven Orchestrator coordinates specialized Executive Agents effectively.
- Agent self-awareness allows for strategic governance and fault recovery.
- Case studies confirm critical throughput sustainability under congestion.
- MTTR is reduced by 86%, enhancing operational resilience.

~2 min readAbstract:Realizing Level 4/5 Autonomous Networks (AN) demands a shift from static automation to agent-native intelligence. Current operations, reliant on rigid scripts, lack the cognitive agency to handle off-nominal conditions. To address this, this letter proposes a hierarchical multi-agent reference architecture enabling high-level autonomy. The framework features a Dual-Driven Orchestrator that coordinates specialized Executive Agents, supported by a shared Public Memory for unified domain knowledge. A key innovation is the integration of agent self-awareness, which empowers the system to harmonize deliberative strategic governance with reflexive fault recovery. We instantiate and validate this architecture within a 5G Core environment. Case studies demonstrate that the system sustains critical throughput under congestion and reduces Mean Time to Repair (MTTR) by 86%, confirming its efficacy in unifying strategic planning with operational resilience.

HOBA (Hierarchical On-policy Bidding Agents) is a novel hierarchical reinforcement learning framework that enhances online advertising bidding systems by improving adaptability and reducing hyperparameter tuning costs. It utilizes a for hyperparameter inference, a SARSA agent for expert model selection, and a dynamic expert pool for bid execution, achieving a +3.6% increase in target cost during large-scale deployment and outperforming state-of-the-art baselines on AuctionNet.
