<b>Abstract</b><p align=\"justify\"> <br /> An Interactive Video on demand (IVoD) system allows users to access video services system in accordance with demanding. Systems consist of video servers as permanent video storage MPEG compression and the numbers of users connected through a high speed network, meanwhile to make use of ATM. Interactive users significant effect to video traffic sent along by video server, until bandwidth network requirement become very fluctuation. <br /> <br /> Congestion occurs at real time video system, then the number of cells losses and can not of a return transmission. Significant effect to quality of picture received by user. So needed strategy for congestion control in order to minimum Quality of Service (QoS) can be reached for all connection. <br /> <br /> This research, congestion control addressed with applied feedback control and threshold mechanism, where if queue the number of cells at buffer exceeds the threshold value, then feedback signal will to send back video source in order to decrease rate arrival traffic. Performance networks observated are throughput, Cell Loss Ratio (CLR) and delay variation. <br /> Research yields show that to have the use of threshold value, increased network throughput and delay, while Cell Loss Ratio (CLR) become descent.
