%X A model-based congestion control algorithm for real-time stream unicast,CRFCC(Congestion Rate Feedback Congestion Control) algorithm based on congestion rate feedback,is proposed in this paper,which utilizes RTP/RTCP to collect QoS information periodically.The proposed algorithm defined two kinds of congestion status,including light congestion and heavy congestion.Herein,we proposed an adaptive control algorithm to adjust sending rate to deal with the congestion.The simulation results on NS2 platform have shown that this algorithm is not only TCP friendly,but also can decrease the probability of re-congestion during the recovery phase.Moreover,the proposed algorithm can maintain the smoothness of sending rate and reduce the rate of packet loss to 2/3 compared with TFRC algorithm.
