Résumé

We consider the problem of network se- lection and flow distribution for a multihomed mobile device. We argue the benefits of a holistic approach which considers user- and application-centric metrics such as quality, energy consumption and monetary cost, rather than the commonly used network-centric metrics. We thus introduce the multihomed flow man- agement problem which combines network selection, flow distribution and application flow awareness. We formulate it as a constrained optimisation problem and compare it to commonly used techniques: single network selection and load balancing. For selected in- teractive applications, we use empirical network mea- surements to evaluate the optimal solutions obtained by the three approaches. We show that, by exploiting the flexibility of application parameters, it is possible to achieve the potentially conflicting goals of maintaining high application quality while reducing both the power consumption and cost of network use.
