【摘要】 针对流媒体传输问题,提出了基于主动网络的可靠多播算法。该算法利用主动路由器的主动服务,能尽早检测到包丢失,对NACK进行有效的抑制、聚合和转发管理,快速进行本地恢复和局部重传。解决了反馈风暴和重传滋扰问题,结果表明:能进行快速而有效的差错恢复,具有很好的可扩展性,适合大规模的流媒体可靠组播应用。更多还原

【Abstract】 For the transmission problem of streaming media,we propose a reliable multicast algorithm based on the active network.Adopting the active services of the active router,this algorithm can detect the packet loss at an early time,provide an effective management of suppression,aggregation and forwarding of NACK,and do the local recovery and partial retransmission quickly.It also solves the problem of feedback implosion and retransmission nuisance.The results showed that this algorithm can do error recovery quickly and effectively, have a good scalability,and is suitable for large-scale multicast applications.更多还原
