Abstract

A queue management method, system, and recording medium include Selective Acknowledgments (SACK) examining to examine SACK blocks of a forwarder to selectively drop packets in a forward flow queue based on a reverse flow queue and MultiPath Transmission Control Protocol (MPTCP) examining configured to perform a first examining to examine multipath headers to recognize MPTCP flows based on a comparison between two subflows being a part of a same superflow and a second examining to examine the reverse flow queue to determine if redundant data has been sent based on a result of the first examining, a packet in the forward flow queue from a prior transmission being dropped from the forward flow queue sent from the forwarder to a receiver if a metadata of the packet does not match a metadata of an acknowledged packet in the reverse flow queue.
