QUIC Throughput and Fairness over Dual Connectivity

Dual Connectivity (DC) is an important lower-layer feature accelerating the transition from 4G to 5G that also expected play role in standalone radio networks. However, even though packet reordering introduced by DC can significantly impact performance of upper-layer protocols, no prior work has studied on QUIC. In this paper, we present first such study. Using a series throughput and fairness experiments, show how QUIC affected different parameters, network conditions, whether implementation aims improve or reliability. Results for two implementations (aioquic, ngtcp2) congestion control algorithms (NewReno, CUBIC) are presented under both static highly time-varying conditions Our findings provide operators with insights understanding into impacts splitting traffic environment. With reasonably selected parameters increased UDP receive buffers, over performs similarly TCP achieves optimal symmetric link when not used duplication. The help modern users better end-to-end service deploying DC.
