The invention discloses a device and a unicast data frame transmission method, the method includes: TRILL package of unicast data frame, adding path mapping information and / or path mapping strategy in the TRILL header, and the transmission of unicast data frame package; in the transmission process, analysis of the head of the TRILL, according to the path mapping information the forwarding path mapped by a first predetermined algorithm, or directly according to the path mapping strategy to complete the forwarding path mapping; forwarding path mapping package using after the acquisition and forwarding the unicast data frame. Through the technical scheme of the invention solves the waste of bandwidth, and packet out of sequence and retransmission, which can be reached in multiple paths between mapping forwarding path and sharing of network load, improve network bandwidth utilization effect.
