摘要
传统流媒体技术采用RTSP-on-TCP/RTP-on-UDP的方式进行交互和数据传输,但UDP在高误码率、带宽波动较剧烈的无线网络中表现不佳。提出了一种RTSP-on-TCP/RTP-on-TCP的双TCP传输方案,并针对目前流行的分布式服务器架构设计了一个简单有效的认证协议,对协议安全性和健壮性作了理论分析,对双TCP的性能进行了实际测试和仿真分析。
Usually, the data of streaming media are transmitted through RTP/RTCP on UDP protocol, which performs poor on wireless net- work channel with high-error-rate and dramatic-fluctuated-bandwidth. A 2-TCP transmit mode and the performance of the 2-TCP is tested and analyzed, with separated TCP connections for RTSP and RTP is proposed. An efficient authorization protocol is designed ,which is suitable for the popular distributed architecture of the streaming media server. The security and robustness of the authorization protocol are analyzed, and the performance of the 2-TCP is tested and analyzed.
