摘要: SCTP协议(Stream Control Transmission Protocol)是一种面向报文的、可靠的传输层协议。它基于不可靠的、无连接的分组IP网络,具有多宿(multi-homing)和多流(multi-streaming)等特性。通过仿真的方法分析,证实SCTP在支持实时多媒体网络应用时的许多性能参数明显优于传统的TCP和UDP,包括数据包投递率、带宽开销、端到端延迟、延迟抖动等。在此基础上,探讨一个适合在流媒体应用中,能够有效提高流媒体传输质量的策略。
关键词: 流传输控制协议, 流媒体, 性能分析
Abstract: Stream Control Transmission Protocol(SCTP) is a message-oriented,reliable transport protocol operating on top of a potentially unreliable connectionless packet service such as IP.It is characterized by multi-homing and multi-streaming.In this paper,we designed and conducted a series of simulation experiments to demonstrate that SCTP may provide significantly advantageous over the traditional TCP and UDP in real-time multimedia applications,in terms of delivery ratio,bandwidth cost,end-to-end delay,jitter,etc.On this basis,we explored a new strategy used to deliver video for streaming media applications with higher quality.
Key words: Stream Control Transmission Protocol(SCTP), media streaming, performance analysis
