Abstract

Abstract: In this paper，an adaptive dynamic layered multicast scheme，ADLM is introduced，to address multicast receivers’ heterogeneity in available bandwidth.ADLM uses an optimal layer rate allocation algorithm which can maximally satisfy each receiver’s available bandwidth.Through a novel feedback aggregate algorithm，ADLM dynamically determines the number of layers and the rate of each layer.Simulation results show that ADLM is TCP-friendly.Meanwhile it can optimize overall throughput.

Key words: layered multicast, congestion control, aggregate algorithm

摘要： 针对多播接收者的可用带宽异构性问题，提出了一种自适应动态分层多播拥塞控制算法（ADLM）。ADLM运用最优化层输率分配算法来自适应地满足接收者的异构性。ADLM可以根据网络情况动态地调整分层的数量以及每一分层的层速率。仿真实验表明，该算法TCP友好的，同时它可以提高系统的吞吐量。
