摘要： The present invention discloses a method and an apparatus for transmitting a unicast data frame. The above mentioned method includes: performing Transparent Interconnection of Lots of Links (TRILL) encapsulation for a unicast data frame, adding path mapping information and/or path mapping policy to a TRILL header, and transmitting the encapsulated unicast data frame (S202); during a transmission procedure, parsing the TRILL header, and implementing forwarding path mapping according to the path mapping information through a first predetermined algorithm or directly according to the path mapping policy (S204); and encapsulating and forwarding the unicast data frame by using a forwarding path obtained through mapping (S206). The technical solution provided by the present invention solves the problems of bandwidth waste and packet disorder or even retransmission, and further achieves the effects of mapping a forwarding path and sharing network load among multiple paths, and of improving network bandwidth utilization ratio.
