Video delivery has become a major challenge for mobile networks. The increasing spread of smartphones, along with the expanding availability of LTE coverage, has contributed to an extensively growing mobile video demand, bringing large volumes of video traffic and far exceeding the capacity of mobile networks. As a result, wireless access congestion is becoming more frequent, degrading the Quality of Experience (QoE) for mobile video consumers. In this paper, the authors present a novel QoE aware traffic management scheme and architecture for scalable video delivery. Thereby, Scalable Video Coding (SVC) is able to organize video data into layers of different importance, thus facilitating the rate adaptation of video streams.
