Cubic is the congestion control algorithm used by default by the Linux kernel since 2.6.15 version. This algorithm is supposed to achieve good scalability and fairness between flows using the same network path, it should also be used by QUIC by default. This patch implements this algorithm and select it as default algorithm for the congestion control. Must be backported to 2.6.
