摘　　要：在分析研究了一些现有可靠组播协议的基础上,提出了一种主动前向纠错的可扩展可靠组播协议AFR,该协议能够使传送丢失数据的恢复包本地化,且只能到达需要它的组播接收者,从而节省了网络资源,降低了对接收者处理能力的要求,而所需要的开销也非常小.The problem of localizing the repair packets when packets are lost during multicast is studied. A new protocol which combines the advantage of FEC and active network technology is presented. In this proposal, repair packets can only reach the receivers that need them and thus the consumption of network bandwidth and receivers' computing capability is reduced. The overhead of this proposal is also very small.
