In Internet Protocol TeleVision (IPTV) systems, Quality-of-Service (QoS) is a critical factor for user satisfaction. In this paper, the authors first propose a queueing model for IPTV systems and discuss how to ensure the QoS of IPTV. They then use the model to analyze the effects of IPTV traffic on other applications in home networks. They find that TCP congestion control may not work well under this circumstance and propose a new approach to improve the performance of TCP. They also verify their results through ns2 simulations.
