Dynamic Optimization of Video Streaming Quality Using Network Digital Twin Technology

Abstract: This paper introduces a novel dynamic optimization framework for video streaming that leverages Network Digital Twin (NDT) technology to address the challenges posed by fluctuating wireless network conditions. Traditional adaptive streaming methods often struggle with rapid changes in network bandwidth, latency, and packet loss, leading to suboptimal user experiences characterized by frequent buffering and reduced video quality. Our proposed framework integrates a sophisticated NDT that models the wireless network in real-time and employs predictive analytics to forecast near-future network states. Utilizing machine learning techniques, specifically Random Forest and Neural Networks, the NDT predicts bandwidth availability, latency trends, and potential packet losses before they impact video transmission. Based on these predictions, our adaptive streaming algorithm dynamically adjusts video bitrates, resolution, and buffering strategies, thus ensuring an uninterrupted and high-quality viewing experience. Experimental validations demonstrate that our approach significantly enhances the Quality of Experience (QoE) by reducing buffering times by up to 50\% and improving resolution in varied network conditions compared to conventional streaming methods. This paper underscores the potential of integrating digital twin technology into multimedia transmission, paving the way for more resilient and user-centric video streaming solutions.
