TCP Emulation at Receivers for Multicast Congestion Control
在接收端模拟TCP的组播拥塞控制协议

TCP emulation at receivers for multicast congestion control protocol is proposed in the paper. The protocol maintains an independent congestion window at each receiver and imitates TCP to change the window size, which is then converted into the expected rate that is a weighted average during a period of time, and then the rate is fed back to the sender. Besides, the mechanism based on the representative is used to suppress the feedbacks and the history discount mechanism is introduced to improve the responsiveness of the protocol. The simulations indicate that the protocol shows good TCP-fairness, smoothness, scalahility and responsiveness, which makes it a good choice for streaming media transportation.
