Cloud computing enables a flexible access to computation and storage services. This requires, for the cloud service provider, mastering network and system issues. During this PhD thesis, we focused on the performance of TCP Cubic, which is the default version of TCP in Linux and thus widely used in today's data centers. Cloud environments...

Dans un réseau WDM, utiliser une nouvelle longueur d'onde dans une fibre demande à recalibrer les autres longueurs d'ondes. Cela génère un coût (e.g., énergétique) qui dépend non linéairement du nombre de longueurs d'ondes utilisant la fibre. Lorsqu'un ensemble de requêtes doivent changer de chemins optiques dans le réseau (lors d'une opération...

In a WDM network, setting up a new wavelength in a fiber requires recalibrating the other wavelengths passing through this fiber. This induces a cost (e.g., time, energy, degradation of QoS) that depends nonlinearly on the number of wavelengths using the fiber. When a set of connection requests must change their optical paths in the network...
