802.11ad链路提供高达6.7 Gbps的数据速率,但仍然非常容易受到阻塞和移动性的影响。另一方面,传统802.11ac/n链路产生低得多的速率,但即使在动态场景下也是鲁棒的。在这项工作中,我们探索使用多路径TCP(MPTCP),同时从事802.11ad和802.11ac接口的性能加速和提高可靠性。我们表明,香草MPTCP在静态条件下实现这些目标,但往往会导致性能比单独使用更快的接口在动态场景下更差。然后,我们设计和实现AMuSe,一个新的MPTCP调度程序,允许MPTCP在所有情况下执行接近最佳。
802.11ad links provide data rates up to 6.7 Gbps but remain highly susceptible to blockage and mobility. On the other hand, legacy 802.11ac/n links yield much lower rates but are robust even under dynamic scenarios. In this work, we explore using Multipath TCP (MPTCP) to engage both 802.11ad and 802.11ac interfaces simultaneously for performance speed-up and improved reliability. We show that vanilla MPTCP achieves these goals under static conditions but often results in performance worse than using the faster interface alone under dynamic scenarios. We then design and implement AMuSe, a new MPTCP scheduler that allows MPTCP to perform near-optimally under all scenarios.
