摘　　要：本文描述了多路径并行传输协议中单路径的超时检测和快速恢复算法,重点解决了因单路径暂时失效而引发的发送缓冲区阻塞问题。通过对单路径的超时检测,可将超时路径中的未确认数据及时向上层抛投,使得其他路径可以继续并行传输。通过在设置的超时时间范围内发送同步心跳包进行路径快速恢复,可避免路径销毁和路径连接的重新建立。In this paper, a timeout detection and fast recovery algorithm of one-path for concurrent multi- path transfer is described, the send buffer blocking caused by one-path temporary timeout is mainly studied. By detecting timeout for one-path and throwing the unacknowledged data to upper layer in time, the algorithm can maintain other paths to continue transferring data. By sending the heartbeat packet continuously in the preset timeout time value, path destruction and continual creation are avoided.
