Abstract: An example method for performance enhancement in a heterogeneous network environment with multipath transport protocols is provided and includes receiving packets according to Transmission Control Protocol (TCP packets) and packets according to multipath TCP (MPTCP packets) in a network environment, determining that TCP packets are experiencing congestion in comparison to the MPTCP packets, and delaying acknowledgement packets (MPTCP ACK packets) corresponding to the MPTCP packets for a pre-determined time interval. In a specific embodiment, a local MPTCP proxy intercepts the TCP packets and forwards underlying data of the TCP packets according to MPTCP.

Abstract: An example method is provided and includes maintaining at a network element a flow table, in which the flow table comprises a plurality of flow table entries and in which each of the flow table entries corresponds to one of a plurality of active data flows in a network, and, subsequent to receipt at the network element of a data packet of one of the active flows, characterizing the one of the active flows as a large flow or a short flow using values contained in the flow table entry corresponding to the one of the active flows. The method further includes processing the received packet in accordance with the characterization.
