Deep Reinforcement Learning Based Autonomous Network Traffic Management and Optimization Framework

Abstract

The rapid growth of modern communication technologies such as cloud computing, Internet of Things (IoT), 5G networks, and multimedia applications has significantly increased the complexity of network traffic management. Traditional traffic engineering methods rely on static routing protocols and predefined policies that are unable to efficiently adapt to dynamic network conditions, resulting in congestion, packet loss, and reduced Quality of Service (QoS). This research proposes a Deep Reinforcement Learning (DRL)-based autonomous network traffic management and optimization framework designed to improve network performance through intelligent and adaptive decision-making. The framework integrates Software-Defined Networking (SDN) architecture with DRL algorithms including Deep Q-Network (DQN) and Proximal Policy Optimization (PPO) to optimize routing paths, bandwidth allocation, congestion control, and load balancing in real time. The proposed system continuously learns from network states and traffic patterns using reward-based optimization mechanisms. Simulation experiments are conducted using Mininet, NS-3, and SDN controllers to evaluate throughput, delay, packet loss, and bandwidth utilization. Experimental results demonstrate that the DRL-based framework significantly outperforms traditional traffic management approaches by reducing latency, minimizing congestion, and improving overall network efficiency. The study contributes toward the development of intelligent, scalable, and self-adaptive communication infrastructures for future autonomous networks
