The Internet is on the way of becoming the universal communication network, and then needs to provide various services and QoS for all kinds of applications. We show in this paper that oscillations that are characteristic of the Internet traffic provokes huge decrease of the QoS that flows can get. After having demonstrated that such oscillations can be characterized by the Hurst (LRD) parameter, we propose an approach for improving Internet flows QoS based on smoothing sending rate of applications. TFRC is a congestion control mechanism that has been issued for this purpose. This paper then proposes an evaluation of TFRC benefits on traffic profile and flows QoS.
