摘要： The invention proposed a method and device for redundant data transmission over multiple wireless links. The method comprises: checking, by a sender, whether a packet to be transmitted by the sender has been successfully transmitted over one of the multiple wireless links; discarding, by the sender, the packet if the checking result is positive. By avoiding unnecessary transmission of redundant packets which have already been successfully transmitted over one of the wireless links, the relative delay between the redundant packets is reduced, such that unnecessary large failover time and inefficient use of radio resources can be mitigated.
