This chapter first provides an outline of the current results in the domains of: (1) QoS/QoE CaM for real-time multimedia services that is supported by SDN, and (2) Big Data analytics and methods that are used for QoS/QoE CaM. Then, three specific use case scenarios with respect to video streaming services are presented, so as to illustrate the expected benefits of incorporating Big Data analytics into SDN-based CaM for the purposes of improving or optimizing QoS/QoE. In the end, we describe our vision and a high-level view of an SDN-based architecture for QoS/QoE CaM that is enriched with Big Data analytics' functional blocks and summarize corresponding challenges.
