可靠组播中基于FEC的随机化差错恢复算法
FEC-based Randomized Error Recovery Algorithm for Reliable Multicast
【摘要】 提出RRMF算法,用向前纠错和重传技术相结合的方式为网络提供可靠组播。FEC通过增加冗余信息的方式提高可靠性。当接收到的信息不足以恢复原始数据时,使用ARQ进行差错恢复。减少了重传发生的次数,从而降低了差错反馈信息和重传数据占用的带宽,适合在大规模交互中使用。
【Abstract】 This paper presented RRMF algorithm which used hybrid FEC/ARQ to provide reliable multicast for the network.FEC improved the reliability by adding redundant information.When the received information was not enough for recovering the original data,ARQ was used to recover the error.This algorithm could reduce the number of transmission times,decrease the error feedback and save the bandwidth,which adapted to large-scale group communication.
