The choice of appropriately accurate but also </span><span class="fontstyle2">practically implementable </span><span class="fontstyle0">measurement algmithms in this context becomes crucial. In<br />this paper, we perform a comparative study of alternative on-line bandwidth allocation algorithms, we analyze their complexity, and </span><span class="fontstyle0">petf01m </span><span class="fontstyle0">comparisons via simulation experiments. Moreover, we argue the relevance of a dynamic measurement time scale approach and demonstrate the effectiveness of this new approach over the static one. Our motivation is to use these algorithms in the data plane of "'self-sizing" frameworks, and make use of their output in taking control plane decisions either locally or globally, in an </span><span class="fontstyle2">on-line </span><span class="fontstyle0">fashion. Previously, no such comprehensive comparison of relevant methods has been carried out, especially from a combined accuracy versus implementation complexity point of view and from the perspective of changing the measurement<br />time scale "dynamically".</span> ER -
