Multipath congestion control with network assistance Abstract   The use of multiple transport flows over distinct, if possible, paths, is a wellknown technique for enhancing the performance and stability of data transfer. Multipath TCPxc2xa0(MPTCP), the most popular multipath transport protocol inuse, allows a single receiver to exploit multiple paths from a single sender. Nevertheless, MPTCP cannot fully exploit the potential gains of multipath connectivity, as it must fairly share resources with regular, singlepath TCP, without knowing whether the available paths are distinct or share bottleneck links, due to IPxe2x80x99s design choices. We introduce a hybrid congestion control algorithm for multipath transport that enables higher bandwidth utilization compared to MPTCP, while remaining friendly to TCPlike flows. Our solution employs (i) Normalized Multiflow Congestion Control (NMCC), a novel endtoend congestion control algorithm and (ii) an innetwork module that exposes routing information to the endusers in order to support the greedy friendliness technique. The endtoend NMCC is architectureindependent and can be seamlessly integrated with MPTCP. The innetwork module has been implemented for the PSI InformationCentric Networking architecture, but it can also be integrated with MultiProtocol Label Switching (MPLS) and Software Defined Networking (SDN). Using an actual protocol implementation deployed on our testbed, as well as on a comprehensive packetlevel simulator, we obtain experimental results which demonstrate clear gains for our design in terms of throughput and friendliness to other flows.

Towards Efficient Parallel Multipathing: A ReceiverCentric CrossLayer Solution to Aid Multipath TCP Applying Multipath TCP (MPTCP) towards transportlayer parallel multipath transmission to increase the throughput performance of mobile devices has attracted considerable attention. Significant results in this area have resulted in many highly promising solutions; however most of the existing solutions follow the conventional sendercentric design and the strict layering principle, without considering the fact that the receiveru0027s intelligence and crosslayer activities can result in distinct performance advantages. In this paper, we propose MPTCPRC, a receivercentric crosslayer solution to aid MPTCP towards efficient parallel multipath data transmission in a wireless environment. In MPTCPRC, the receiver performs path usage decision and crosslayer activity, by making use of its acquired firsthand knowledge of both transport layer and MAC layer, rather than only giving feedback to the sender then waiting for the decision. We evaluate and demonstrate the benefits of our proposal by simulations.
