| 摘 要： | 本文提出了一种新的多速率多播拥塞控制策略,以满足分层多播接收者的可用带宽异构性。这种接收方驱动的拥塞控制策略,能够根据网络情况变化动态地调整分层的数量及层速率,运用最优层速率分配算法来满足接收者的可用带宽异构性,接收者的可用带宽可以用根据TCP友好经验公式计算出。仿真实验表明,该算法在TCP友好性上有良好的性能,同时它可以明显提高系统的吞吐量。

| Abstract: | This paper introduced a new multi-rate multicast congestion control strategies to meet layered multicast receivers' heterogeneity in available bandwidth.This receiver-driven congestion control strategy,adjusting the the number of layers and the rate of each layer dynamically according to the changes of network situation,using the optimal layer rate allocation algorithm to meet the receivers' heterogeneity in available bandwidth.TCP-equation is a generally used to estimate receivers' the available bandwidth.... |
