| 摘 要： | 文章在分析了以前的各种算法后,提出了一种改进的基于RTP/RTCP的实时多媒体自适应传输控制策略。与先前的基于分组丢失率确定网络状态的算法相比,该策略利用RTP/RTCP收集的QoS信息———延时抖动来进一步分析网络状态,实现主动进行带宽调整以减少报文丢失,减少流的抖动,提高流的平稳特性,提高系统的性能。

| Abstract: | After the analysis of previous algor it hm,a modified adaptive transmitted control strategy for Real Time Multimedia i s provided.Compared with previous algorithm using packets loss capability to co nfirm the state of network,the strategy utilizes information of QoS that collec ted by RTP/RTCP—— — interarrival jitter to analyze the state of network,realizes bandwidth adju stment voluntarily to reduce packet loss,reduce the jitter of stream,improve the calm characteristic of stream,improve the performance of system. |
