Abstract

Cubic TCP [1] is a high-speed TCP variant protocol which has been the default TCP implementation in Linux since kernel-2.6.18. In high bandwidth-delay product environment, it can achieve a full utilization of the available bandwidth. However, Cubic TCP has a shortcoming in terms of convergence speed [4]. In this paper, we verify the slow convergence problem of Cubic TCP on testbed. After that, we propose an improved fast convergence mechanism which is called Cubic with Faster Convergence. The feature of this new mechanism is that we use a new bandwidth releasing method instead of simply cut down ssthresh directly. Testbed experiments show that this new mechanism can significantly reduce the convergence time, at the same time, do not affect other performance of Cubic TCP.
