From green networking to network virtualization: some interesting problems arising from telecommunication applications
Résumé
Telecommunication networks and, more broadly, information and communication technology (ICT), are integral components to the optimization community.
In this talk, we introduce optimization problems we have tackled in collaboration with telecommunication experts over the past decade. The first half focuses on energy-aware network management, highlighting the importance of efficient routing and dynamic device switching. This approach is crucial for reducing energy consumption without compromising quality of service (QoS).
The second part of the presentation explores a problem arising from the convergence of network and computing systems: the placement and routing of Virtual Network Functions (VNFs). This
second application involves a novel combination of network design and facility location optimization. Our contributions include mathematical programming models, a comprehensive analysis
of their performance in a realistic setting, and a comparative analysis of its computational complexity compared to current state-of-the-art formulations.
