SDN-Based 6G Video Content Delivery Technique via Multi-Path Routing, Multi-Server Architecture and Multi-Connectivity

With the rise of 6G networks, ensuring optimal video content delivery under conditions of high mobility and data volume becomes increasingly complex. This paper presents a novel SDN-based video content delivery technique tailored for 6G, which combines Multi-Path Routing, Multi-Server Architecture, and Multi-Connectivity to meet growing user demands for high-quality video streaming. Our approach integrates these three technologies to optimize data flow and ensure seamless, uninterrupted video transmission. Multi-path routing dynamically distributes data across multiple paths, minimizing latency and improving throughput. The multi-server architecture enhances system reliability and fault tolerance by distributing video content across several servers, reducing load on individual nodes. With multi-threaded downloading, the video is transmitted simultaneously through multiple streams from distributed servers, accelerating data transfer and enhancing system efficiency. Multi-connectivity, in turn, allows seamless transitions between base stations, ensuring stable connections, especially in high-mobility environments. We implement and test this combined solution in an SDN environment using 6G network parameters, focusing on its ability to adapt to network conditions and maintain high Quality of Experience (QoE) for the end-user. Our results demonstrate that this integrated approach efficiently optimizes network resources while delivering high-quality video, including 8K/16K streams, making it well-suited for future 6G networks.
