An Efficient MPTCP-Based Congestion Control Scheme for HBDP Networks

Abstract

With the widespread distribution of devices with multiple network interfaces, interest in multi-path transmission techniques has increased. The Internet Engineering Task Force (IETF) published Multi-path TCP (MPTCP) as a standard for multi-path transmission techniques and many researchers have studied multipath means of transmitting data efficiently, with each path having different characteristics. However, today’s networks have been shown to exhibit high bandwidth-delay product (HBDP) characteristics but MPTCP does not match the requirements of HBDP networks. Many researchers have proposed solutions to overcome this problem, but the solutions have had the drawbacks of ineffective load balancing mechanisms and a trade-off problem between improving throughput and preventing loss events. In this paper, we propose an efficient MPTCP-based congestion control scheme in HBDP networks. Our scheme consists of two main mechanisms. One is to mitigate trade-off problems observed in previous works and the other is to enhance traffic migration according to the conditions of each path. Simulation results have shown that our scheme achieves those goals and enhance performance in HBDP networks.
