摘要
组播是一人发送多人接收的技术,但它是不可靠的。这些年出现了许多可靠多播协议,论文先评价了两种可靠组播协议优缺点,同时引入了第三种组播协议——异步分层编码协议,并全面介绍了异步分层编码的协议框架和一些实现方法,最后给出了异步分层编码协议在DVB网络上的一个应用。
Multicast is a technology that one send data and several receive data.It is known to us all;multicast is unreliable.So many reliable multicast protocols have been designed.In this article,we introduce a reliable multicast protocol,whose name is Asynchronous Layered Coding.We interpret the framework of ALC and methods to build it.At last,we Implement a reliable file multicasting system on DVB(Digital Video Broadcasting)network.
