Özet

In this article we investigate the impacts of interspacing and source polling policies on the cell-loss rates in transmission of variable bit rate video sources over Asynchronous Transfer Mode networks. We present a mathematical model that finds the approximate optimal starting times of the video sources that minimize the congestion at the multiplexer. Combined with the approximate optimal source starting times, we propose a source ordering and polling policy for reducing the cell-loss rates. The proposed policy is tested against alternative policies using simulation of pre-recorded video data.
