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.



We would like thank our shepherd, Moritz Steiner, and the anonymous PAM reviewers for their valuable feedback. We also thank our colleagues Eduard Rubinstein, Vijay Nanjundan, James Flynn, and Atreya Praveen for their helpful discussions and assistance.
