摘　　要：文章在仔细分析研究了RTP/RTCP实时传输协议的基础上,阐明了RTP/RTCP协议的基本原理。提出了一种嵌入式Linux平台下RTP/RTCP协议栈的设计模型与实现方案,并且详细论述了解决网络时延抖动的JitterBuffer机制。该设计与实现方案目前已应用于基于嵌入式Linux平台的媒体网关中,完全能够满足该媒体网关对于多路语音实时传输的通信需求。This paper clarifies the rationale of RTP/RTCP real time protocol after a careful analysis,And then it discusses the Jitter Buffer mechanism in detail,which can solve the jitter and delay problems in the network,Finally it presents a design model and implementation of RTP/RTCP protocol stack under embedded Linux environment,This solution is already adopted in the Media Gateway based on embedded Linux platform and it meets the requirements of multi-session real time communication well.
