Poster: Fairness Improvement Method Using ECNs with Different Congestion Control Algorithms within QUIC

QUIC is a transport protocol that adds congestion control, retransmission control, and TLS to UDP. QUIC can use the same congestion control algorithms as TCP. In previous work, when both CUBIC and BBR flows compete within QUIC, we have shown that communication performance becomes unfair with respect to the buffer size of the shared bottleneck link. In this study, we improve the communication performance at different bottleneck link buffer sizes using Round Trip Time (RTT) and Explicit Congestion Notification (ECN) when CUBIC and BBR compete within QUIC through actual experiments.
