Dual-Mode Congestion Control Mechanism for Video Services

Video services represent over a half of Internet traffic. However, there is not any congestion control mechanism which would be suitable and widely used for all kinds of video services. This paper provides a study in which this kind of congestion control mechanism is further developed and improved based on the findings of our previous study. This mechanism offers a specific approach for congestion control because it can offer dual-mode congestion control services. There is a backward loading mode where the bandwidth is given away to other connections after the load level of a network exceeds a certain level. Instead, the other mode, a real-time mode, always wants its fair share of the bandwidth.
