Abstract: A method and apparatus for performing multipath transmission of a data packet. The method includes: setting, by an electronic apparatus performing multipath transmission of a data packet, a multipath network to another electronic apparatus, and setting a re-transmission leased path used for performing packet re-transmission; dividing a data packet into a plurality of sub-packets, and assigning the sub-packets to the multipath network; transmitting the sub-packets by using the assigned multipath; and checking a transmission error of the sub-packet, and re-transmitting the sub-packet in which a transmission error has occurred by using the re-transmission leased path.
