摘要
该文给出了一个端到端的适应性多媒体流控制策略,称为基于丢失延时的算法LDA(loss-delaybasedalgo-rithm),它调整多媒体流的发送行为,以符合网络的当前拥塞状况。LDA算法利用实时传输协议RTP(real-timetransportprotocol)来收集分组丢失和延时统计信息,并用来调整发送端的发送行为,使它和TCP的拥塞控制有类似的统计特性,是TCP友好的。仿真的结果显示LDA算法对于网络资源的利用、拥塞避免和TCP流的公平性都是比较好的。
This paper presents an end-to-end adaptation scheme ,called the loss -delay based adaptation algorithm(LDA),for regulating the transmission behavior of multimedia senders in accordance with the network congestion state.LDA uses the real-time transport protocol(RTP)for collecting loss and delay statistics which are then used for adjusting the transmission behavior of the senders in a manner similar to TCP connections suffering from similar losses and de-lays.Performance results collected using simulations and measurements over the Internet suggest the efficiency of LDA in terms of network utilization,congestion avoidance and fairness towards competing TCP connections.
