On the adaptive bandwidth provisioning schemes

In this paper we first construct a common classification guideline for adaptive provisioning schemes by introducing the feature tree concept. Afterward, we propose QoS-aware provisioning schemes that combine the use of the Gaussian traffic model, traffic measurements, and traffic predictions. In parallel, we give an overview on the recent adaptive provisioning schemes. We perform extensive numerical and simulative investigations to show that our proposed QoS-aware schemes outperform some previously available ones from the aspect of efficiency. Moreover, we point out the practical tradeoff between using buffered and bufferless constraints in QoS-aware schemes.
