Emerging multimedia applications in the Internet characterizes the trend of service convergence in one only infrastructure. These new types of media can, however, be harmful to other flows sharing the same infrastructure, such as TCP-based applications. The most common problem is fairness, due to the unresponsive behavior of UDP flows. This article presents a fairness regulation scheme based on an adaptive QoS management architecture, where nodes are responsible for certain level of management operations, like surveillance and parameter tuning. An adaptive meta-behavior is defined in order to adjust scheduling parameters according to UDP/TCP traffic ratio.
