摘　　要：随着流媒体技术的发展,传统的传输控制协议TCP严格有序、确认重传的方式,以及基于用户数据报UDP的流媒体传输方案中RTP与RTCP速率调整都不能很好地满足流媒体的传输要求。针对流媒体数据的特点及其对网络的特殊要求,结合流控制传输协议SCTP多宿主、多流、可配置的无序递交等特性,论证基于SCTP协议的新型流媒体传输方案能够更好地满足流媒体传输,并在ns-allinone-2.28环境下进行仿真验证。结果显示基于SCTP协议的新型流媒体传输方案具有更低的丢报率,更能提升流媒体传输性能。With the development of streaming media technology,the traditional transport protocol TCP which is strictly ordered and retransmitted by acknowledgement and the RTP and RTCP rate adjustment in the streaming media transmission scheme based on UDP can＇t meet the demand of streaming media transmission.Considering the characteristics of streaming media and the special requirements of the network and combining the stream control transmission protocol with the characteristics of multihoming,multistreaming and configurable disordered transmission and so on, demonstrates the new streaming media transmission scheme based on SCTP can suit the streaming media transmission better.The results under the environment of ns-allinone-2.28 show that the new streaming media transmission scheme based on SCTP has a lower loss rate and can better enhance the performance of streaming media transmission.
