摘要 对两种基于UDP实时流媒体拥塞控制机制——探讨基于丢包率的控制和基于往返时延(Round-trip Time,RTT)的控制,提出一种在接收端通过单向延时预测拥塞的算法。与前两种拥塞驱动机制相比,单向时延自适应拥塞控制算法(AOWDCC)最大限度地缩短了拥塞反馈时间间隔,拥塞判断的实时性大大增强。采用NS模拟器,对基于丢包率的拥塞控制、基于RTT的拥塞控制和AOWDCC算法的性能进行仿真,验证了AOWDCC的优越性。 This paper analyzes and discusses two congestion control mechanism in the continuous media stream communications in which UDP Is used. one is based on loss-rate, the other is based on RTT, and it points out each deficiency. It proposes a congestion control mechanism AOWDcC bascd on one way delay. Test in network simulate proves the superiority of the mechanism.
