Abstract :
Buffer management plays an important role for enhancing quality of service (QoS) for video streaming over IP networks. However, most existing buffer management techniques have been developed according to the network´s point of view; consequently, QoS requirements from users´ perspectives are not well satisfied. The paper proposes a novel buffer management scheme based on user´s expectations. Simulation results show the advantages of the scheme in terms of video quality, service fairness and network efficiency.
