摘　　要：1 引言使用多播(multicast)进行实时连续媒体传输已成为音频/视频广播、音频/视频会议工具等许多Internet应用的重要组成部分.Mbone(Multicast Backbone)[1]是建立在Internet之上的具有IP多播能力的虚拟覆盖网,在过去十年中,随着Mbone的迅速发展,在Internet上提供多播传输服务已逐渐成为现实.在Internet上进行连续媒体多播有两类不同的方法:Continuous media multicast has been an important component of many networked services such as audio-visual broadcast and video conferencing. The problems of scalability, congestion control, heterogeneity and reliability, which confront Internet continuous media multicast, are presented first, and then the overview of the adaptive rate control schemes and techniques to solve these problems are stated. Finally, we discuss some trends and unsolved issues in the field.
