In this paper, we propose an architecture for network traffic prioritization. This architecture is application and protocol agnostic. We also give an interface for this architecture which enables QoE triggered fast network interface switching without interrupting the communication sessions. We give an algorithm in order to minimize the cost of the frequent network changes (reordering and retransmissions) and evaluate its performance in simulations and demonstrating it on real Wi-Fi and cellular access network. To demonstrating the effectiveness of our QoE triggered switching approach we eliminate the stalling events on YouTube video playback.
