Flow forwarding is a core concept of SDN, where the SDN controller dynamically manages and directs the flow of packets based on network policies. For multimedia traffic, precise control over forwarding paths ensures that real-time data (like video or voice) is prioritized to minimize latency, jitter, and packet loss.
QoE estimation (B) is important for evaluating user experience but is more of a monitoring task rather than a design concern.
When designing a network for transmitting multimedia traffic using an SDN-based model, an architect should consider the aspect of QoE estimation (Quality of Experience).
QoE estimation refers to the measurement and assessment of the perceived quality of multimedia content by end users. In the context of SDN, it involves evaluating the quality of multimedia traffic in real-time and making decisions based on that assessment to ensure optimal user experience.
