摘　　要：多播通信中的故障恢复已经成为网络界关注的一个热点的课题.好的多播故障恢复方案可以节省网络资源,减低网络延迟和开销,实现故障的快速恢复.本文在研究其它多播容错算法和网络编码的基础上,提出了一个新的多播容错方案RM-FSNC.本方案克服了以往多播容错方案多出现的无法处理节点故障、不可预知等问题,在一定程度上优化了时间、网络开销及避免了环路问题.RM-FSNC方案将网络编码应用到多播网络中,在一定程度上提高了网络的安全性和容量,降低资源的消耗,建立快速高效的保护路径,从而提供了多播网络的可靠性.Fault recovery of multicast communication has become a hot issue of network area. Good multicast fault recovery scheme can save network resources,reduce the network latency and overhead,realize fast fault recovery. This article is inspired by the past multicast fault-tolerant algorithm and network coding,proposes a new multicast fault-tolerant scheme RM-FSNC. This scheme can overcome the problems such as the node failure and more unpredictable problems that the traditional multicast fault-tolerant schemes could not handle. To a certain extent,it can optimize the time,reduce the network overhead and avoid the loop problem. The RM-FSNC scheme can apply network coding to the multicast network,so the security of the network and capacity are improved,the consumption of resources are reduced. It can establish a fast and efficient protection path,thus providing the reliability of multicast network.
