Existing multipath transfer protocols do not sufficiently consider the multipath asymmetry, so they are not able to achieve the best throughput with asymmetry paths. A multipath throughput model was used to develop a minimum feedback delay (MFD) ACK (acknowledgement) path selection algorithm. This algorithm selects the fastest reverse path through network measurements for the ACK packets, which improves end-to-end throughput by reducing the round trip time of each path. The throughput gain over aggregated TCP Reno and its upper bound is given and verified by simulations. The throughput is compared with existing ACK selection algorithms by simulations to show that this algorithm can achieve higher end-to-end throughput.
