应用层多播作为一种新兴的多点数据传输模式,其拥塞控制机制却仍未提出一个成熟有效的方案,这成为了限制其广泛应用的一个瓶颈.提出一种流媒体代理多播系统,数据传输过程中采用基于客户端和基于代理的双层拥塞控制模型,最后实验证明该拥塞控制模型可以使系统充分利用网络带宽,提高了视频服务质量.

Although Application-level multicast is a new multi-point data transmission model,there is no mature and effective scheme for its congestion control mechanism,which has become a bottleneck in its wide application.This thesis has pmposed a proxy-based media stream multicast system which has used client based and proxy based 2-tier congestion control model.Finally the simulation results have proved that this congestion control model can help the system adequately utilize the network bandwidth and improve the quality of video service.
