To address this, we propose a framework using graph neural networks (GNNs) and deep reinforcement learning (DRL). GNNs model network components as nodes and connections as edges, learning efficient representations to improve metrics like delay, jitter, load balancing, and scalability. Our approach delivers scalable, real-time SDN optimization, significantly outperforming QT in simulations, paving the way for advanced data-driven network control.
