The increase of mobile subscribers' requests and the explosion of multimedia services such as provided by the IP Multimedia Subsystem (IMS) are making QoS management more and more complex. In fact, with the emergence of the Software Defined Network (SDN) paradigm which enables dynamic configuration of network resources and flexible QoS management, Next Generation Networks (NGN) have found necessary to integrate this new concept. The aim of this paper is twofold. First, to present a new architecture SDN-based for Next Generation Networks (NGN) to enhance the QoS management. The architecture is implemented and evaluated for a Video on Demand (VoD) in IMS network. Second, to demonstrate the implementation of the proposed architecture by testing the Quality of Experience (QoE) which is evaluated in terms of the Video Mean Opinion Score (VMOS).
