【摘要】 针对Intranet底层对组播提供的支持并不明确这一问题,提出了一种混播,即组播和单播相结合的实时多媒体传输方案。该方案通过构造分配树,使用其分支结点转发数据的方法,以实现一对多的分布式多媒体传输。文章还对混播技术在实现时遇到的多媒体数据发送、重传、网络拥塞调整以及安全管理等问题作了具体的讨论。更多还原

【Abstract】 In this papers a mixed-transmission technology for real-time multimedia is proposed,which aims to settle the problem whether the Intranet infrastructure can support multicasting.It suggests to build a distribution tree,where a father node transmits data to his children nodes,to acquire an one-to-many distributed multimedia transmission.Moreover,the paper discusses the problems encountered in the application of mixed-transmission technology,such as sending,resend-ing,congestion control and safety management.更多还原
