摘要

本文通过对真实Android应用程序的广泛实验研究，探讨了智能手机中多路径TCP (MPTCP)的潜在好处和缺陷。我们考虑了不同类型的应用程序——上传密集型与下载密集型、网络密集型与交互式——以及各种网络条件，并研究了MPTCP对性能、能耗和CPU利用率的影响。我们的研究结果表明，MPTCP在智能手机应用程序中的好处低于理论上的预期;在某些情况下，MPTCP实际上会损害性能和能耗。我们的研究结果可以为智能手机设计师和移动应用开发商提供见解，以改善用户体验和延长智能手机电池寿命。

Multipath TCP in Smartphones: Impact on Performance, Energy, and CPU Utilization

This paper explores the potential benefits and pitfalls of Multipath TCP (MPTCP) in smartphones via an extensive experimental study over real Android applications. We consider different types of applications - upload vs. download intensive, network intensive vs. interactive - and a variety of network conditions, and we study the impact of MPTCP on performance, energy consumption, and CPU utilization. Our results reveal that the benefits of MPTCP in smartphone apps are lower than expected in theory; in several cases, MPTCP in fact can hurt both performance and energy consumption. Our findings can provide insights to smartphone designers and mobile app developers towards improving user experience and extending smartphone battery life.
