QUIC is a secure, general-purpose transport protocol using congestion and retransmission controls on User Datagram Protocol (UDP). QUIC can use the same congestion control algorithms as Transmission Control Protocol (TCP). Thus, when communication between multiple terminals using QUIC competes, the performance of each terminal depends on the congestion control algorithm adopted by the terminal. In related works, the communication performance was evaluated by simulation when both CUBIC and BBR flows competed in TCP, and the results showed that each communication performance became unfair with the buffer size of the shared bottleneck link. In addition, since the communication volume of QUIC is increasing year by year, there may be cases where TCP communication conflicts with QUIC communication. In this study, we verify the communication performance at different bottleneck link buffer sizes when BBR and CUBIC compete, and when TCP and QUIC compete through tested real experiments. |
