@misc{Jaskóła_Przemysław_Simultaneous, author={Jaskóła, Przemysław and Arabas, Piotr and Karbowski, Andrzej}, howpublished={online}, publisher={Zielona Góra: Uniwersytet Zielonogórski}, language={eng}, abstract={The issue of energy-aware traffic engineering has become prominent in telecommunications industry in the last years. This paper presents a two-criteria network optimization problem, in which routing and bandwidth allocation are determined jointly, so as to minimize the amount of energy consumed by a telecommunication infrastructure and to satisfy given demands represented by a traffic matrix. A scalarization of the criteria is proposed and the choice of model parameters is discussed in detail.}, abstract={The model of power dissipation as a function of carried traffic in a typical software router is introduced. Then the problem is expressed in a form suitable for the mixed integer quadratic programming (MIQP) solver. The paper is concluded with a set of small, illustrative computational examples. Computed solutions are implemented in a testbed to validate the accuracy of energy consumption models and the correctness of the proposed traffic engineering algorithm.}, type={artykuł}, title={Simultaneous routing and flow rate optimization in energy-aware computer networks}, keywords={MINLP, MIQP, network optimization, green networking, fairness, multi-criteria}, }
