For the data of stereo video is much larger and the current network's bandwidth cannot be upgraded immediately,it is easy to cause the netw ork congestion problem in transmission. An end-to-end transmission control mechanism is proposed. In NS-2 platform,according to the feedback information,the number of packet loss is calculated in the feedback internal of RTP / RTCP and the characteristics of different frames w ith different importance,an active packet loss method at the sending is adopted to discard the less important data and to ensure the more important data transmit in advance. Experimental results show that the method can effectively protect important frames and increase frames w hich can be decoded and the smoothness of the video. Compared w ith congestion control of w ithout the protection,the decoded frames can be increased by more than 25%.
