Reliable available bandwidth estimation based on distinguishing queuing regions and resolving false estimations [video transmission]

Video transmission needs a stable sending rate in order that the video can be displayed showing uniform quality. In addition, a lower packet loss rate is rather helpful in reducing video quality degradation. Therefore, reliable available bandwidth estimation becomes an indispensable step towards robust transmission of multimedia data. The existing available bandwidth estimation methods cannot deal with the false estimation problem and thereby precise estimation is impossible. In this paper, we propose a reliable available bandwidth estimation method, based on distinguishing queuing regions and resolving false estimations. Promising simulation results indicate that our method can obtain the available bandwidth precisely, no matter what the network environment is; single-bottleneck or multiple-bottleneck.
