Using MPTCP subflow association control for heterogeneous wireless network optimization
Jianwei Liu, Anjan Rayamajhi, James Martin · 2016
Multipath TCP (MPTCP) was designed to increase the throughput and reliability of TCP, with specific motivation coming from scenarios including data center and cloud computing. The use of MPTCP has been recently explored to support heterogeneous wireless networks (HetNets) involving hosts that have multiple network interfaces. However, current solutions generally involve many simplifying assumptions. In this paper, we propose a new framework to collect scheduling information from various scheduling network entities and conduct optimization from a global view. The framework uses the existing or readily accessible MPTCP parameters. Under this framework, we introduce a centralized optimization algorithm to realize general proportional fairness of user throughput. Based on results from NS3 simulations, we provide evidence that the approach provides a low cost solution for improved performance from the perspectives of both applications and network operators.
