The heterogeneity and lacking of QoS guarantee make the application of this technique a challenge. In this paper, we analyze the difficulties in streaming media multicast design, survey technologies that have been proposed for it. We also discuss several congestion control and error control mechanisms. Finally we present some remained issues for further research.展开更多
