Video streaming has become a dominant form of digital content consumption, with user expectations for seamless, high-quality experiences steadily rising. This book presents a video streaming framework built on Multipath TCP (MPTCP) and Software Defined Networking (SDN) to enhance Quality of Experience (QoE). A key innovation is the use of a Genetic Algorithm (GA) to dynamically select optimal transmission paths based on bandwidth, latency, and link reliability, enabling adaptability in changing network conditions. Beyond path selection, the architecture incorporates service differentiation to prioritize video traffic and ensure fairness, along with durability enhancements to reduce playback interruptions. These combined mechanisms create an intelligent, adaptive system that delivers robust, high-quality video streaming across diverse network environments. The results show that this approach significantly improves user experience and meets service expectations across different user classes.
