4G长期演进(LTE)网络呈现出大容量和终端用户移动性的新特征。这些挑战导致了对具有移动用户的LTE网络中的TCP拥塞控制算法的有效性的理解的差距。为了进一步了解，我们进行了一项详细的测量研究，在美国第一级无线运营商的高速驾驶场景中，将TCP Cubic与瓶颈带宽和往返传播时间(BBR)进行了比较-这是谷歌开发的一种新的拥塞控制替代方案。我们的结果表明，Cubic和BBR通常具有相似的吞吐量，但BBR的自身造成的延迟明显低于Cubic。
4G Long Term Evolution (LTE) networks present new features of high capacities together with end-user mobility. These challenges have led to a gap in the understanding of the effectiveness of TCP congestion control algorithms in LTE networks with mobile users. To further understanding, we conduct a detailed measurement study comparing TCP CUBIC with Bottleneck Bandwidth and Round-trip propagation time (BBR) – a new congestion control alternative developed by Google – in a high-speed driving scenario over a tier-1 U.S. wireless carrier. Our results show CUBIC and BBR generally have similar throughputs, but BBR has significantly lower self-inflicted delays than CUBIC.
