接收端驱动的流媒体组播拥塞控制协议

提出了一种适于流媒体业务的TCP公平的单速率组播拥塞控制协议——接收端驱动的二项式组播拥塞控制算法．该算法在各接收端独立维护拥塞窗口，采用二项式算法调整拥塞窗口，根据当前拥塞窗口值计算出期望接收速率，采用基于代表的策略实现反馈和反馈抑制．算法很好改善了丢失路径多样性问题，增强了可扩展性．仿真表明协议具有良好的TCP公平性、速率平滑性、可扩展性和较好的响应性．

A receiver-driven multicast congestion control algorithm for streaming media applications

A TCP-friendly single rate multicast congestion control for streaming media applications called the Binomial congestion control at Receivers for Multicast(BARM) is proposed. The protocol maintains a congestion window independently at each receiver instead of at the sender, and adopts the binomial algorithm to adjust the congestion window from which an expected receiving rate of the receiver is calculated. To suppress feedback implosion, the representative approach is used. The protocol improves the scalability and reduces the impact of the LPM problem greatly. Simulations indicate that BARM shows good TCP-friendliness, smoothness, scalability, and acceptable responsiveness.
